ProgressBar

open class ProgressBar : View
kotlin.Any
   ↳ android.view.View
   ↳ android.widget.ProgressBar

A user interface element that indicates the progress of an operation. Progress bar supports two modes to represent progress: determinate, and indeterminate. For a visual overview of the difference between determinate and indeterminate progress modes, see Progress & activity. Display progress bars to a user in a non-interruptive way. Show the progress bar in your app's user interface or in a notification instead of within a dialog.

Indeterminate Progress

Use indeterminate mode for the progress bar when you do not know how long an operation will take. Indeterminate mode is the default for progress bar and shows a cyclic animation without a specific amount of progress indicated. The following example shows an indeterminate progress bar:

<ProgressBar
       android:id="@+id/indeterminateBar"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       />
  

Determinate Progress

Use determinate mode for the progress bar when you want to show that a specific quantity of progress has occurred. For example, the percent remaining of a file being retrieved, the amount records in a batch written to database, or the percent remaining of an audio file that is playing.

To indicate determinate progress, you set the style of the progress bar to android.R.style#Widget_ProgressBar_Horizontal and set the amount of progress. The following example shows a determinate progress bar that is 25% complete:

<ProgressBar
       android:id="@+id/determinateBar"
       style="@android:style/Widget.ProgressBar.Horizontal"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:progress="25"/>
  
You can update the percentage of progress displayed by using the setProgress(int) method, or by calling incrementProgressBy(int) to increase the current progress completed by a specified amount. By default, the progress bar is full when the progress value reaches 100. You can adjust this default by setting the android:max attribute.

Other progress bar styles provided by the system include:

The "inverse" styles provide an inverse color scheme for the spinner, which may be necessary if your application uses a light colored theme (a white background).

open fun setIndeterminate(indeterminate: Boolean): Unit

Change the indeterminate mode for this progress bar. In indeterminate mode, the progress is ignored and the progress bar shows an infinite animation instead.

Define the drawable used to draw the progress bar in indeterminate mode.

For the Drawable to animate, it must implement Animatable, or override Drawable#onLevelChange(int). A Drawable that implements Animatable will be animated via that interface and therefore provides the greatest amount of customization. A Drawable that only overrides onLevelChange(int) is animated directly by ProgressBar and only the animation duration, repeating behavior, and interpolator can be modified, and only before the indeterminate animation begins.

Parameters
d Drawable!: the new drawable

Parameters
d Drawable!: the new drawable

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

setIndeterminateTintMode

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

Parameters
context Context!: The application environment

setProgress

Added in API level 24
open fun setProgress(
    progress: Int,

setProgressBackgroundTintBlendMode

Added in API level 29

Parameters
secondaryProgress Int: the new secondary progress, between getMin() and getMax()

setSecondaryProgressTintBlendMode

Added in API level 29
open fun setSecondaryProgressTintBlendMode(blendMode: BlendMode?): Unit

Specifies the blending mode used to apply the tint specified by setSecondaryProgressTintList(android.content.res.ColorStateList)} to the secondary progress indicator. The default mode is PorterDuff.Mode#SRC_ATOP.

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

setSecondaryProgressTintList

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

Applies a tint to the secondary progress indicator, if one exists. Does not modify the current tint mode, which is PorterDuff.Mode#SRC_ATOP by default.

The secondary progress indicator must be specified as a layer with id android.R.id#secondaryProgress in a LayerDrawable used as the progress drawable.

Subsequent calls to setProgressDrawable(android.graphics.drawable.Drawable) where the drawable contains a secondary progress indicator 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

setSecondaryProgressTintMode

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

Specifies the blending mode used to apply the tint specified by setSecondaryProgressTintList(android.content.res.ColorStateList)} to the secondary progress indicator. The default mode is PorterDuff.Mode#SRC_ATOP.

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

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 progress changes and the default state description will not be used. App developers can restore the default behavior by setting the argument to null. If set progress 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.

    oldw: Int,
    oldh: Int
): Unit
Parameters

h Int: Current height of this view.
oldw Int: Old width of this view.

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.
