Question

I want to rotate a Button view by 45 degrees. For that I have written the code which is shown below. Now rather than rotating the Button itself, the text or label on the Button is getting rotated. But I want the Button to get rotated by 45 degrees. How can I accomplish this?

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;
    }
}

I believe you need to apply RotateAnimation to the view, with fillAfter set to true to keep it’s angle. The above example works on the layout, but you could apply the animation to a view (in your case, the button).
