EditorInfo

IME_ACTION_DONE

public static final int IME_ACTION_DONE

Bits of IME_MASK_ACTION: the action key performs a "done" operation, typically meaning there is nothing more to input and the IME will be closed.

Constant Value: 6 (0x00000006)

IME_ACTION_GO

public static final int IME_ACTION_GO

Bits of IME_MASK_ACTION: the action key performs a "go" operation to take the user to the target of the text they typed. Typically used, for example, when entering a URL.

Constant Value: 2 (0x00000002)

IME_ACTION_NEXT

public static final int IME_ACTION_NEXT

Bits of IME_MASK_ACTION: the action key performs a "next" operation, taking the user to the next field that will accept text.

Constant Value: 5 (0x00000005)

IME_ACTION_NONE

public static final int IME_ACTION_NONE

Bits of IME_MASK_ACTION: there is no available action.

Constant Value: 1 (0x00000001)

IME_ACTION_PREVIOUS

public static final int IME_ACTION_PREVIOUS

Bits of IME_MASK_ACTION: like IME_ACTION_NEXT, but for moving to the previous field. This will normally not be used to specify an action (since it precludes IME_ACTION_NEXT), but can be returned to the app if it sets IME_FLAG_NAVIGATE_PREVIOUS.

Constant Value: 7 (0x00000007)

IME_ACTION_SEARCH

public static final int IME_ACTION_SEARCH

Bits of IME_MASK_ACTION: the action key performs a "search" operation, taking the user to the results of searching for the text they have typed (in whatever context is appropriate).

Constant Value: 3 (0x00000003)

IME_ACTION_SEND

public static final int IME_ACTION_SEND

Bits of IME_MASK_ACTION: the action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message in IM or SMS where sending is immediate.

Constant Value: 4 (0x00000004)

IME_ACTION_UNSPECIFIED

public static final int IME_ACTION_UNSPECIFIED

Bits of IME_MASK_ACTION: no specific action has been associated with this editor, let the editor come up with its own if it can.

Constant Value: 0 (0x00000000)

IME_FLAG_FORCE_ASCII

public static final int IME_FLAG_FORCE_ASCII

Flag of imeOptions: used to request an IME that is capable of inputting ASCII characters. The intention of this flag is to ensure that the user can type Roman alphabet characters in a TextView. It is typically used for an account ID or password input. A lot of the time, IMEs are already able to input ASCII even without being told so (such IMEs already respect this flag in a sense), but there are cases when this is not the default. For instance, users of languages using a different script like Arabic, Greek, Hebrew or Russian typically have a keyboard that can't input ASCII characters by default. Applications need to be aware that the flag is not a guarantee, and some IMEs may not respect it. However, it is strongly recommended for IME authors to respect this flag especially when their IME could end up with a state where only languages using non-ASCII are enabled.

Constant Value: -2147483648 (0x80000000)

IME_FLAG_NAVIGATE_NEXT

public static final int IME_FLAG_NAVIGATE_NEXT

Flag of imeOptions: used to specify that there is something interesting that a forward navigation can focus on. This is like using IME_ACTION_NEXT, except allows the IME to be multiline (with an enter key) as well as provide forward navigation. Note that some IMEs may not be able to do this, especially when running on a small screen where there is little space. In that case it does not need to present a UI for this option. Like IME_ACTION_NEXT, if the user selects the IME's facility to forward navigate, this will show up in the application at InputConnection.performEditorAction(int).

Constant Value: 134217728 (0x08000000)

IME_FLAG_NAVIGATE_PREVIOUS

public static final int IME_FLAG_NAVIGATE_PREVIOUS

Flag of imeOptions: like IME_FLAG_NAVIGATE_NEXT, but specifies there is something interesting that a backward navigation can focus on. If the user selects the IME's facility to backward navigate, this will show up in the application as an IME_ACTION_PREVIOUS at InputConnection.performEditorAction(int).

Constant Value: 67108864 (0x04000000)

IME_FLAG_NO_ACCESSORY_ACTION

public static final int IME_FLAG_NO_ACCESSORY_ACTION

Flag of imeOptions: used in conjunction with one of the actions masked by IME_MASK_ACTION, this indicates that the action should not be available as an accessory button on the right of the extracted text when the input method is full-screen. Note that by setting this flag, there can be cases where the action is simply never available to the user. Setting this generally means that you think that in fullscreen mode, where there is little space to show the text, it's not worth taking some screen real estate to display the action and it should be used instead to show more text.

Constant Value: 536870912 (0x20000000)

IME_FLAG_NO_ENTER_ACTION

public static final int IME_FLAG_NO_ENTER_ACTION

Flag of imeOptions: used in conjunction with one of the actions masked by IME_MASK_ACTION. If this flag is not set, IMEs will normally replace the "enter" key with the action supplied. This flag indicates that the action should not be available in-line as a replacement for the "enter" key. Typically this is because the action has such a significant impact or is not recoverable enough that accidentally hitting it should be avoided, such as sending a message. Note that TextView will automatically set this flag for you on multi-line text views.

Constant Value: 1073741824 (0x40000000)

IME_FLAG_NO_EXTRACT_UI

public static final int IME_FLAG_NO_EXTRACT_UI

Flag of imeOptions: used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind, through transparent UI parts in the fullscreen IME. The part of the UI visible to the user may not be responsive to touch because the IME will receive touch events, which may confuse the user; use IME_FLAG_NO_FULLSCREEN instead for a better experience. Using this flag is discouraged and it may become deprecated in the future. Its meaning is unclear in some situations and it may not work appropriately on older versions of the platform.

Constant Value: 268435456 (0x10000000)

IME_FLAG_NO_FULLSCREEN

public static final int IME_FLAG_NO_FULLSCREEN

Flag of imeOptions: used to request that the IME never go into fullscreen mode. By default, IMEs may go into full screen mode when they think it's appropriate, for example on small screens in landscape orientation where displaying a software keyboard may occlude such a large portion of the screen that the remaining part is too small to meaningfully display the application UI. If this flag is set, compliant IMEs will never go into full screen mode, and always leave some space to display the application UI. Applications need to be aware that the flag is not a guarantee, and some IMEs may ignore it.

Constant Value: 33554432 (0x02000000)

IME_FLAG_NO_PERSONALIZED_LEARNING

public static final int IME_FLAG_NO_PERSONALIZED_LEARNING

Flag of imeOptions: used to request that the IME should not update any personalized data such as typing history and personalized language model based on what the user typed on this text editing object. Typical use cases are:

• When the application is in a special mode, where user's activities are expected to be not recorded in the application's history. Some web browsers and chat applications may have this kind of modes.
• When storing typing history does not make much sense. Specifying this flag in typing games may help to avoid typing history from being filled up with words that the user is less likely to type in their daily life. Another example is that when the application already knows that the expected input is not a valid word (e.g. a promotion code that is not a valid word in any natural language).

Applications need to be aware that the flag is not a guarantee, and some IMEs may not respect it.

Constant Value: 16777216 (0x01000000)

IME_MASK_ACTION

public static final int IME_MASK_ACTION

Set of bits in imeOptions that provide alternative actions associated with the "enter" key. This both helps the IME provide better feedback about what the enter key will do, and also allows it to provide alternative mechanisms for providing that command.

Constant Value: 255 (0x000000ff)

IME_NULL

public static final int IME_NULL

Generic unspecified type for imeOptions.

Constant Value: 0 (0x00000000)

CREATOR

public static final Creator<EditorInfo> CREATOR

Used to make this class parcelable.

actionId

public int actionId

If actionLabel has been given, this is the id for that command when the user presses its button that is delivered back with InputConnection.performEditorAction().

actionLabel

public CharSequence actionLabel

In some cases an IME may be able to display an arbitrary label for a command the user can perform, which you can specify here. This is typically used as the label for the action to use in-line as a replacement for the "enter" key (see actionId). Remember the key where this will be displayed is typically very small, and there are significant localization challenges to make this fit in all supported languages. Also you can not count absolutely on this being used, as some IMEs may ignore this.

contentMimeTypes

public String[] contentMimeTypes

List of acceptable MIME types for InputConnection.commitContent(InputContentInfo, int, Bundle).

null or an empty array means that InputConnection.commitContent(InputContentInfo, int, Bundle) is not supported in this editor.

extras

public Bundle extras

Any extra data to supply to the input method. This is for extended communication with specific input methods; the name fields in the bundle should be scoped (such as "com.mydomain.im.SOME_FIELD") so that they don't conflict with others. This field can be filled in from the R.attr.editorExtras attribute of a TextView.

fieldId

public int fieldId

Identifier for the editor's field. This is optional, and may be 0. By default it is filled in with the result of View.getId() on the View that is being edited.

fieldName

public String fieldName

Additional name for the editor's field. This can supply additional name information for the field. By default it is null. The actual contents have no meaning.

hintLocales

public LocaleList hintLocales

List of the languages that the user is supposed to switch to no matter what input method subtype is currently used. This special "hint" can be used mainly for, but not limited to, multilingual users who want IMEs to switch language context automatically.

null means that no special language "hint" is needed.

Editor authors: Specify this only when you are confident that the user will switch to certain languages in this context no matter what input method subtype is currently selected. Otherwise, keep this null. Explicit user actions and/or preferences would be good signals to specify this special "hint", For example, a chat application may be able to put the last used language at the top of hintLocales based on whom the user is going to talk, by remembering what language is used in the last conversation. Do not specify TextView.getTextLocales() only because it is used for text rendering.

hintText

public CharSequence hintText

The "hint" text of the text view, typically shown in-line when the text is empty to tell the user what to enter.

imeOptions

public int imeOptions

Extended type information for the editor, to help the IME better integrate with it.

initialCapsMode

public int initialCapsMode

The capitalization mode of the first character being edited in the text. Values may be any combination of TextUtils.CAP_MODE_CHARACTERS, TextUtils.CAP_MODE_WORDS, and TextUtils.CAP_MODE_SENTENCES, though you should generally just take a non-zero value to mean "start out in caps mode".

initialSelEnd

public int initialSelEnd

The text offset of the end of the selection at the time editing begins; -1 if not known. Keep in mind that, without knowing the cursor position, many IMEs will not be able to offer their full feature set and may behave in unpredictable ways: pass the actual cursor position here if possible at all.

Also, this needs to be the cursor position right now, not at some point in the past, even if input is starting in the same text field as before. When the app is filling this object, input is about to start by definition, and this value will override any value the app may have passed to InputMethodManager.updateSelection(android.view.View, int, int, int, int) before.

initialSelStart

public int initialSelStart

The text offset of the start of the selection at the time editing begins; -1 if not known. Keep in mind that, without knowing the cursor position, many IMEs will not be able to offer their full feature set and may even behave in unpredictable ways: pass the actual cursor position here if possible at all.

Also, this needs to be the cursor position right now, not at some point in the past, even if input is starting in the same text field as before. When the app is filling this object, input is about to start by definition, and this value will override any value the app may have passed to InputMethodManager.updateSelection(android.view.View, int, int, int, int) before.

inputType

public int inputType

The content type of the text box, whose bits are defined by InputType.

label

public CharSequence label

A label to show to the user describing the text they are writing.

packageName

public String packageName

Name of the package that owns this editor.

IME authors: In API level 22 Build.VERSION_CODES.LOLLIPOP_MR1 and prior, do not trust this package name. The system had not verified the consistency between the package name here and application's uid. Consider to use InputBinding.getUid(), which is trustworthy. Starting from Build.VERSION_CODES.M, the system verifies the consistency between this package name and application uid before EditorInfo is passed to the input method.

Editor authors: Starting from Build.VERSION_CODES.M, the application is no longer able to establish input connections if the package name provided here is inconsistent with application's uid.

privateImeOptions

public String privateImeOptions

A string supplying additional information options that are private to a particular IME implementation. The string must be scoped to a package owned by the implementation, to ensure there are no conflicts between implementations, but other than that you can put whatever you want in it to communicate with the IME. For example, you could have a string that supplies an argument like "com.example.myapp.SpecialMode=3". This field is can be filled in from the R.attr.privateImeOptions attribute of a TextView.

EditorInfo

public EditorInfo ()

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

dump

public void dump (Printer pw, 
                String prefix)

Write debug output of this object.

getInitialSelectedText

public CharSequence getInitialSelectedText (int flags)

Gets the selected text, if any. May be null when the protocol is not supported or the selected text is way too long.

getInitialSurroundingText

public SurroundingText getInitialSurroundingText (int beforeLength, 
                int afterLength, 
                int flags)

Gets the surrounding text around the current cursor, with beforeLength characters of text before the cursor (start of the selection), afterLength characters of text after the cursor (end of the selection), and all of the selected text.

The initial surrounding text for return could be trimmed if oversize. Fundamental trimming rules are:

• The text before the cursor is the most important information to IMEs.
• The text after the cursor is the second important information to IMEs.
• The selected text is the least important information but it shall NEVER be truncated. When it is too long, just drop it.

For example, the subText can be viewed as TextBeforeCursor + Selection + TextAfterCursor. The result could be:

1. (maybeTrimmedAtHead)TextBeforeCursor + Selection + TextAfterCursor(maybeTrimmedAtTail)
2. (maybeTrimmedAtHead)TextBeforeCursor + TextAfterCursor(maybeTrimmedAtTail)

getInitialTextAfterCursor

public CharSequence getInitialTextAfterCursor (int length, 
                int flags)

Get length characters of text after the current cursor position. May be null when the protocol is not supported.

getInitialTextBeforeCursor

public CharSequence getInitialTextBeforeCursor (int length, 
                int flags)

Get length characters of text before the current cursor position. May be null when the protocol is not supported.

getInitialToolType

public int getInitialToolType ()

Returns the initial MotionEvent.ACTION_UP tool type MotionEvent.getToolType(int) responsible for focus on the current editor.

getSupportedHandwritingGesturePreviews

public Set<Class<? extends PreviewableHandwritingGesture>> getSupportedHandwritingGesturePreviews ()

Returns the combination of Stylus handwriting gesture preview types supported by the current Editor. For an editor that supports Stylus Handwriting. InputMethodManager.startStylusHandwriting, it also declares supported gesture previews.

Note: A supported gesture EditorInfo.getSupportedHandwritingGestures() may not have preview supported EditorInfo.getSupportedHandwritingGesturePreviews().

getSupportedHandwritingGestures

public List<Class<? extends HandwritingGesture>> getSupportedHandwritingGestures ()

Returns the combination of Stylus handwriting gesture types supported by the current Editor. For an editor that supports Stylus Handwriting. InputMethodManager.startStylusHandwriting, it also declares supported gestures.

isStylusHandwritingEnabled

public boolean isStylusHandwritingEnabled ()

Returns true when an Editor has stylus handwriting enabled. false by default.

isWritingToolsEnabled

public boolean isWritingToolsEnabled ()

Returns true when an Editor has writing tools enabled. true by default for all editors. Toolkits can optionally disable them where not relevant e.g. passwords, number input, etc.

makeCompatible

public final void makeCompatible (int targetSdkVersion)

Ensure that the data in this EditorInfo is compatible with an application that was developed against the given target API version. This can impact the following input types: InputType.TYPE_TEXT_VARIATION_WEB_EMAIL_ADDRESS, InputType.TYPE_TEXT_VARIATION_WEB_PASSWORD, InputType.TYPE_NUMBER_VARIATION_NORMAL, InputType.TYPE_NUMBER_VARIATION_PASSWORD.

This is called by the framework for input method implementations; you should not generally need to call it yourself.

setInitialSurroundingSubText

public void setInitialSurroundingSubText (CharSequence subText, 
                int subTextStart)

Editors may use this method to provide initial input text to IMEs. As the surrounding text could be used to provide various input assistance, we recommend editors to provide the complete initial input text in its View.onCreateInputConnection(EditorInfo) callback. When trimming the input text is needed, call this method instead of setInitialSurroundingText(CharSequence) and provide the trimmed position info. Always try to include the selected text within subText to give the system best flexibility to choose where and how to trim subText when necessary. Starting from VERSION_CODES.S, spans that do not implement Parcelable will be automatically dropped.

setInitialSurroundingText

public void setInitialSurroundingText (CharSequence sourceText)

Editors may use this method to provide initial input text to IMEs. As the surrounding text could be used to provide various input assistance, we recommend editors to provide the complete initial input text in its View.onCreateInputConnection(EditorInfo) callback. The supplied text will then be processed to serve #getInitialTextBeforeCursor, #getInitialSelectedText, and #getInitialTextBeforeCursor. System is allowed to trim sourceText for various reasons while keeping the most valuable data to IMEs. Starting from VERSION_CODES.S, spans that do not implement Parcelable will be automatically dropped.

Editor authors: Providing the initial input text helps reducing IPC calls for IMEs to provide many modern features right after the connection setup. We recommend calling this method in your implementation.

setInitialToolType

public void setInitialToolType (int toolType)

Set the initial MotionEvent.ACTION_UP tool type MotionEvent.getToolType(int). that brought focus to the view.

setStylusHandwritingEnabled

public void setStylusHandwritingEnabled (boolean enabled)

Set true if the Editor has stylus handwriting enabled. false by default, Editor must set it true to indicate that it supports stylus handwriting.

setSupportedHandwritingGesturePreviews

public void setSupportedHandwritingGesturePreviews (Set<Class<? extends PreviewableHandwritingGesture>> gestures)

Set the Handwriting gesture previews supported by the current Editor. For an editor that supports Stylus Handwriting InputMethodManager.startStylusHandwriting, it is also recommended that it declares supported gesture previews.

Note: A supported gesture EditorInfo.getSupportedHandwritingGestures() may not have preview supported EditorInfo.getSupportedHandwritingGesturePreviews().

If editor doesn't support one of the declared types, gesture preview will be ignored.

setSupportedHandwritingGestures

public void setSupportedHandwritingGestures (List<Class<? extends HandwritingGesture>> gestures)

Set the Handwriting gestures supported by the current Editor. For an editor that supports Stylus Handwriting InputMethodManager.startStylusHandwriting, it is also recommended that it declares supported gestures.

If editor doesn't support one of the declared types, IME will not send those Gestures to the editor. Instead they will fallback to using normal text input.

Note: A supported gesture may not have preview supported getSupportedHandwritingGesturePreviews().

setWritingToolsEnabled

public void setWritingToolsEnabled (boolean enabled)

Set false if Editor opts-out of writing tools, that enable IMEs to replace text with generative AI text.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Used to package this object into a Parcel.
