Constructor Detail

Columns

public Columns(int columnCount)

Create spec layer that will evenly divide current bounds in given number of columns and then draw all child layers in each

Parameters:

columnCount - number of columns, must be a positive integer

Columns

public Columns(int columnCount,
               int initialCapacity)

Create spec layer that will evenly divide current bounds in given number of columns and then draw all child layers in each

Parameters:

columnCount - number of columns, must be a positive integer

initialCapacity - anticipated number of child layers

Columns

protected Columns()

Create spec layer that will evenly divide current bounds in given number of columns and then draw all child layers in each.

This is a minimum constructor for the factory — only paints and reusable objects are initialized. Developers extending this class are responsible for setting all fields to proper argument values.

Method Detail

setColumnCount

public Columns setColumnCount(int columnCount)

Set the number of columns

Parameters:

columnCount - number of columns, must be a positive integer

Returns:

this for chaining

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

Overrides:

draw in class AbstractSpecLayerGroup<Columns>

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.
