Parameters
state Parcelable!: The frozen state that had previously been returned by onSaveInstanceState.

onSaveInstanceState

Added in API level 1
open fun onSaveInstanceState(): Parcelable?
Return
Parcelable? Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save.

performClick

Added in API level 1
open fun performClick(): Boolean
Return
Boolean True there was an assigned OnClickListener that was called, false otherwise is returned.

setButtonDrawable

Added in API level 1
open fun setButtonDrawable(resId: Int): Unit

Sets a drawable as the compound button image given its resource identifier.

Parameters
resId Int: the resource identifier of the drawable

setButtonDrawable

Added in API level 1
open fun setButtonDrawable(drawable: Drawable?): Unit

Sets a drawable as the compound button image.

Parameters
drawable Drawable?: the drawable to set This value may be null.

setButtonIcon

Added in API level 31
open fun setButtonIcon(icon: Icon?): Unit

Sets the button of this CompoundButton to the specified Icon.

Parameters

setButtonTintBlendMode

Added in API level 29
open fun setButtonTintBlendMode(tintMode: BlendMode?): Unit

Specifies the blending mode used to apply the tint specified by setButtonTintList(android.content.res.ColorStateList)} to the button drawable. The default mode is PorterDuff.Mode#SRC_IN.

Parameters
tintMode BlendMode?: the blending mode used to apply the tint, may be null to clear tint

setButtonTintList

Added in API level 21
open fun setButtonTintList(tint: ColorStateList?): Unit

Applies a tint to the button drawable. Does not modify the current tint mode, which is PorterDuff.Mode#SRC_IN by default.

Subsequent calls to setButtonDrawable(android.graphics.drawable.Drawable) will automatically mutate the drawable and apply the specified tint and tint mode using Drawable#setTintList(ColorStateList).

Parameters
tint ColorStateList?: the tint to apply, may be null to clear tint

setButtonTintMode

Added in API level 21
open fun setButtonTintMode(tintMode: PorterDuff.Mode?): Unit

Specifies the blending mode used to apply the tint specified by setButtonTintList(android.content.res.ColorStateList)} to the button drawable. The default mode is PorterDuff.Mode#SRC_IN.

Parameters
tintMode PorterDuff.Mode?: the blending mode used to apply the tint, may be null to clear tint

setChecked

Added in API level 1
open fun setChecked(checked: Boolean): Unit

Changes the checked state of this button.

Parameters
checked Boolean: true to check the button, false to uncheck it

setOnCheckedChangeListener

Added in API level 1
open fun setOnCheckedChangeListener(listener: CompoundButton.OnCheckedChangeListener?): Unit

Register a callback to be invoked when the checked state of this button changes.

Parameters
listener CompoundButton.OnCheckedChangeListener?: the callback to call on checked state change This value may be null.

setStateDescription

Added in API level 30
open fun setStateDescription(stateDescription: CharSequence?): Unit

This function is called when an instance or subclass sets the state description. Once this is called and the argument is not null, the app developer will be responsible for updating state description when checked state changes and we will not set state description in setChecked. App developers can restore the default behavior by setting the argument to null. If setChecked is called first and then setStateDescription is called, two state change events will be merged by event throttling and we can still get the correct state description.

Parameters
stateDescription CharSequence?: The state description. This value may be null.

toggle

Added in API level 1
open fun toggle(): Unit

Protected methods

drawableStateChanged

Added in API level 1
protected open fun drawableStateChanged(): Unit

onCreateDrawableState

Added in API level 1
protected open fun onCreateDrawableState(extraSpace: Int): IntArray!
Parameters
extraSpace Int: if non-zero, this is the number of extra entries you would like in the returned array in which you can place your own states.
Return
IntArray! Returns an array holding the current Drawable state of the view.

onDraw

Added in API level 1
protected open fun onDraw(canvas: Canvas): Unit
Parameters
canvas Canvas: the canvas on which the background will be drawn This value cannot be null.

verifyDrawable

Added in API level 1
protected open fun verifyDrawable(who: Drawable): Boolean

If your view subclass is displaying its own Drawable objects, it should override this function and return true for any Drawable it is displaying. This allows animations for those drawables to be scheduled.

Be sure to call through to the super class when overriding this function.
If you override this method you must call through to the superclass implementation.

Parameters
who Drawable: This value cannot be null.
Return
Boolean boolean If true then the Drawable is being displayed in the view; else false and it is not allowed to animate.
