Method Detail

draw

public void draw(android.graphics.Canvas canvas,
                 android.graphics.Rect drawableBounds)

Description copied from interface: RhythmSpecLayer

Draw itself to the provided canvas within provided bounds according to internal configuration (if any)

Specified by:

draw in interface RhythmSpecLayer

Parameters:

canvas - Canvas for the layer to draw itself to

drawableBounds - Bounds where this layer should draw itself. Since these are the bounds of a RhythmDrawable connected to the view, they are usually the same as the view’s bounds, so you can use this parameter to get the view’s dimensions should you need them.

addLayer

public T addLayer(RhythmSpecLayer layer)

Add a spec layer to this group. Note: by default, calling this method DOESN'T trigger redraw. If you are calling this when overlay is already displayed and want to have changes displayed immediately, you also must call View.invalidateDrawable(Drawable) or similar yourself.

Specified by:

addLayer in interface RhythmSpecLayerParent

Parameters:

layer - A Rhythm spec layer

Returns:

this for chaining

size

public int size()

Return the number of children in this layer group

Returns:

number of children
