ShapeDrawable重绘View的例子

直接上段代码吧:

public class CustomDrawableView extends View {
	private ShapeDrawable mDrawable;

	public CustomDrawableView(Context context) {
		super(context);

		int x = 10;
		int y = 10;
		int width = 300;
		int height = 50;
                //通过传参可以绘制不同的图形
		mDrawable = new ShapeDrawable(new OvalShape());
		mDrawable.getPaint().setColor(0xff74AC23);
		mDrawable.setBounds(x, y, x + width, y + height);
	}

	protected void onDraw(Canvas canvas) {
		mDrawable.draw(canvas);
	}
}
