I'm trying to do the same thing with a SeekBar subclass. But I'm not
having much success either. Here's my code.
import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.widget.SeekBar;
public class SlideBar extends SeekBar {
public SlideBar(Context context) {
super(context);
}
public SlideBar(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public SlideBar(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
}
protected void onDraw(Canvas c)
{
c.rotate(90);
}
}
