将字体旋转一下

今天突然想起这个问题 然后试了一下其实也不难

public class UpsideDownText extends TextView  {

 @Override
 protected void onDraw(Canvas canvas) {
  // TODO Auto-generated method stub
  
          canvas.save();  
 
               float py = this.getHeight()/2.0f;
        float px = this.getWidth()/2.0f;
       
        canvas.rotate(180, px, py);  
       
               
        super.onDraw(canvas);
      
        canvas.restore();
 }

 public UpsideDownText(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);
  // TODO Auto-generated constructor stub
 }

 public UpsideDownText(Context context, AttributeSet attrs) {
  super(context, attrs);
  // TODO Auto-generated constructor stub
 }

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

}
