Constructor Details

ScaleDrawable

public ScaleDrawable(Drawable drawable,
 int gravity,
 float scaleWidth,
 float scaleHeight)

Creates a new scale drawable with the specified gravity and scale properties.

Parameters:

drawable - the drawable to scale

gravity - gravity constant (see Gravity used to position the scaled drawable within the parent container

scaleWidth - width scaling factor [0...1] to use then the level is at the maximum value, or -1 to not scale width

scaleHeight - height scaling factor [0...1] to use then the level is at the maximum value, or -1 to not scale height

Method Details

setGravity

public void setGravity(int gravity)

setScaleWidth

public void setScaleWidth(float scaleWidth)

setScaleHeight

public void setScaleHeight(float scaleHeight)

draw

public void draw(@NonNull
 Canvas canvas)

Description copied from class: Drawable

Draw in its bounds (set via setBounds) respecting optional effects such as alpha (set via setAlpha).

Overrides:

draw in class DrawableWrapper

Parameters:

canvas - The canvas to draw into

onLevelChange

protected boolean onLevelChange(int level)

Description copied from class: Drawable

Override this in your subclass to change appearance if you vary based on level.

Overrides:

onLevelChange in class DrawableWrapper

Returns:

Returns true if the level change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last level.

onBoundsChange

protected void onBoundsChange(@NonNull
 Rect bounds)

Description copied from class: Drawable

Override this in your subclass to change appearance if you vary based on the bounds.

Overrides:

onBoundsChange in class DrawableWrapper
