Method Detail

setFading

public void setFading(Drawable d)

Sets the image for the fading layer. This drawable's opacity will vary directly proportionally to the progress value. It's invisible when progress == 0 and fully opaque when progress == 1.

setBase

public void setBase(Drawable d)

Sets the image for the base layer. This drawable's opacity remains fixed. It's fully visible when progress == 0, and completely obscured when progress == 1.

setProgress

public void setProgress(float progress)

draw
