| protected void | onBoundsChange(Rect bounds)
super.onBoundsChange(bounds);
updateShape();
|
| protected void | onDraw(android.graphics.drawable.shapes.Shape shape, Canvas canvas, Paint paint)Called from the drawable's draw() method after the canvas has been set
to draw the shape at (0,0). Subclasses can override for special effects
such as multiple layers, stroking, etc.
shape.draw(canvas, paint);
|
| public void | setAlpha(int alpha)Set the alpha level for this drawable [0..255]. Note that this drawable
also has a color in its paint, which has an alpha as well. These two
values are automatically combined during drawing. Thus if the color's
alpha is 75% (i.e. 192) and the drawable's alpha is 50% (i.e. 128), then
the combined alpha that will be used during drawing will be 37.5%
(i.e. 96).

| public void | setColorFilter(ColorFilter cf)
mShapeState.mPaint.setColorFilter(cf);
|
| public void | setDither(boolean dither)

|
| public void | setIntrinsicHeight(int height)Sets the intrinsic (default) height for this shape.
mShapeState.mIntrinsicHeight = height;
|
| public void | setIntrinsicWidth(int width)Sets the intrinsic (default) width for this shape.
mShapeState.mIntrinsicWidth = width;
|
| public void | setPadding(Rect padding)Sets padding for this shape, defined by a Rect object.
Define the padding in the Rect object as: left, top, right, bottom.
if (padding == null) {
mShapeState.mPadding = null;
} else {
if (mShapeState.mPadding == null) {
mShapeState.mPadding = new Rect();
}
mShapeState.mPadding.set(padding);
}
|
| public void | setPadding(int left, int top, int right, int bottom)Sets padding for the shape.
if ((left | top | right | bottom) == 0) {
mShapeState.mPadding = null;
} else {
if (mShapeState.mPadding == null) {
mShapeState.mPadding = new Rect();
}
mShapeState.mPadding.set(left, top, right, bottom);
}
|
| public void | setShaderFactory(android.graphics.drawable.ShapeDrawable$ShaderFactory fact)Sets a ShaderFactory to which requests for a
{@link android.graphics.Shader} object will be made.
mShapeState.mShaderFactory = fact;
|
| public void | setShape(android.graphics.drawable.shapes.Shape s)Sets the Shape of this ShapeDrawable.
mShapeState.mShape = s;
updateShape();
|
| private void | updateShape()
if (mShapeState.mShape != null) {
