ProgressBar


public class ProgressBar
extends View

java.lang.Object
   ↳ 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 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).

Accessibility

Consider using AccessibilityNodeInfo#setMinDurationBetweenContentChanges(Duration) to convey to accessibility services that changes can be throttled. This may reduce the frequency of potentially disruptive notifications.

Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.

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.

setStateDescription

Added in API level 30
public void setStateDescription (CharSequence stateDescription)

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.

Protected methods

drawableStateChanged

Added in API level 1
protected void drawableStateChanged ()

This function is called whenever the state of the view changes in such a way that it impacts the state of drawables being shown.

If the View has a StateListAnimator, it will also be called to run necessary state change animations.

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

onAttachedToWindow

Added in API level 1
protected void onAttachedToWindow ()

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).
If you override this method you must call through to the superclass implementation.

onDetachedFromWindow

Added in API level 1
protected void onDetachedFromWindow ()

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.
If you override this method you must call through to the superclass implementation.

onDraw

Added in API level 1
protected void onDraw (Canvas canvas)

Implement this to do your drawing.

Parameters
canvas Canvas: the canvas on which the background will be drawn This value cannot be null.

onMeasure

Added in API level 1
protected void onMeasure (int widthMeasureSpec, 
                int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' onMeasure(int, int) is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

Parameters
widthMeasureSpec int: horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

heightMeasureSpec int: vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

onSizeChanged

Added in API level 1
protected void onSizeChanged (int w, 
                int h, 
                int oldw, 
                int oldh)

This is called during layout when the size of this view has changed. If you were just added to the view hierarchy, you're called with the old values of 0.

Parameters
w int: Current width of this view.

h int: Current height of this view.

oldw int: Old width of this view.

oldh int: Old height of this view.

verifyDrawable

Added in API level 1
protected boolean verifyDrawable (Drawable who)

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.

Returns
boolean boolean If true then the Drawable is being displayed in the view; else false and it is not allowed to animate.
