Method Details

setThumb

public void setThumb(Drawable thumb)

Sets the thumb that will be drawn at the end of the progress meter within the SeekBar.

If the thumb is a valid drawable (i.e. not null), half its width will be used as the new thumb offset (@see #setThumbOffset(int)).

Returns:

The current thumb drawable

setThumbTintList

Applies a tint to the thumb drawable.

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

Parameters:

thumbOffset - The offset amount in pixels.

setSplitTrack

public void setSplitTrack(boolean splitTrack)

Specifies whether the track should be split by the thumb. When true, the thumb's optical bounds will be clipped out of the track drawable, then the thumb will be drawn into the resulting gap.

setKeyProgressIncrement

public void setKeyProgressIncrement(int increment)

Sets the amount of progress changed via the arrow keys.

Parameters:

increment - The amount to increment or decrement when the user presses the arrow keys.

getKeyProgressIncrement

public int getKeyProgressIncrement()

Returns the amount of progress changed via the arrow keys.

By default, this will be a value that is derived from the progress range.

Returns:

The amount to increment or decrement when the user presses the arrow keys. This will be positive.

verifyDrawable

protected boolean verifyDrawable(@NonNull
 Drawable who)

Description copied from class: View

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.

Overrides:

verifyDrawable in class ProgressBar

Parameters:

who - The Drawable to verify. Return true if it is one you are displaying, else return the result of calling through to the super class.

Returns:

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

See Also:

• View.unscheduleDrawable(Drawable)
• View.drawableStateChanged()

jumpDrawablesToCurrentState

public void jumpDrawablesToCurrentState()

Description copied from class: View

Call Drawable.jumpToCurrentState() on all Drawable objects associated with this view.

Also calls StateListAnimator.jumpToCurrentState() if there is a StateListAnimator attached to this view.

Overrides:

jumpDrawablesToCurrentState in class ProgressBar

drawableStateChanged

protected void drawableStateChanged()

Description copied from class: View

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.

Overrides:

drawableStateChanged in class ProgressBar

See Also:

• Drawable.setState(int[])

drawableHotspotChanged

public void drawableHotspotChanged(float x,
 float y)

Description copied from class: View

This function is called whenever the view hotspot changes and needs to be propagated to drawables or child views managed by the view.

Dispatching to child views is handled by View.dispatchDrawableHotspotChanged(float, float).

Be sure to call through to the superclass when overriding this function.

Overrides:

drawableHotspotChanged in class ProgressBar

Parameters:

x - hotspot x coordinate

y - hotspot y coordinate

onSizeChanged

protected void onSizeChanged(int w,
 int h,
 int oldw,
 int oldh)

Description copied from class: View

Called when width or height changed

Overrides:

onSizeChanged in class ProgressBar

Parameters:

w - new width

h - new height

oldw - previous width

oldh - previous height

onMeasure

protected void onMeasure(int widthMeasureSpec,
 int heightMeasureSpec)

Description copied from class: View

Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.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 View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling super.onMeasure() 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 the base one to provide better measurements of their content.

Overrides:

onMeasure in class ProgressBar

Parameters:

widthMeasureSpec - width measure specification imposed by the parent MeasureSpec

heightMeasureSpec - height measure specification imposed by the parent MeasureSpec

onDraw

protected void onDraw(@NonNull
 Canvas canvas)

Description copied from class: View

Draw the content of this view, implement this to do your drawing.

Note that (0, 0) will be the top left of the bounds, and (width, height) will be the bottom right of the bounds.

Overrides:

onDraw in class ProgressBar

Parameters:

canvas - the canvas to draw content

drawTickMarks

protected void drawTickMarks(Canvas canvas)

onTouchEvent

public boolean onTouchEvent(@NonNull
 MotionEvent event)

Description copied from class: View

Implement this method to handle touch screen motion events.

If this method is used to detect click actions, it is recommended that the actions be performed by implementing and calling View.performClick(). This will ensure consistent system behavior.

Overrides:

onTouchEvent in class View

Parameters:

event - the touch event

Returns:

true if the event was handled by the view, false otherwise

onKeyDown

public boolean onKeyDown(int keyCode,
 @NonNull
 KeyEvent event)

Description copied from class: View

Default implementation: perform press of the view when KeyEvent.KEY_ENTER, KeyEvent.KEY_KP_ENTER or KeyEvent.KEY_SPACE is released, if the view is enabled and clickable.

Overrides:

onKeyDown in class View

Parameters:

keyCode - a key code that represents the button pressed, from KeyEvent

event - the KeyEvent object that defines the button action

onRtlPropertiesChanged

public void onRtlPropertiesChanged(int layoutDirection)

Description copied from class: View

Called when any RTL property (layout direction or text direction or text alignment) has been changed.

Subclasses need to override this method to take care of cached information that depends on the resolved layout direction, or to inform child views that inherit their layout direction.

The default implementation does nothing.

Overrides:

onRtlPropertiesChanged in class View

Parameters:

layoutDirection - the direction of the layout

See Also:

• View.LAYOUT_DIRECTION_LTR
• View.LAYOUT_DIRECTION_RTL
