我想将Button视图旋转45度.为此,我编写了如下所示的代码.现在,不是旋转Button本身,而是按钮上的文本或标签会旋转.但我希望按钮旋转45度.我怎么能做到这一点？

public class MyButton extends Button {

    public float degrees;
    public float sWidth;
    public float sHeight;

    public MyButton(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onDraw(Canvas canvas) {
        // TODO Auto-generated method stub

        canvas.save();
        canvas.rotate(45.0f);
        super.onDraw(canvas);

        canvas.restore();
    }

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        // TODO Auto-generated method stub
        super.onSizeChanged(w, h, oldw, oldh);
        sWidth=w;
        sHeight=h;
    }
}
