游戏中的View开发

public class MyView extends View {
 private int textX = 20,textY = 20;
 
 public MyView(Context context) {
  super(context);
  setFocusable(true);
 }
 
 @Override
 protected void onDraw(Canvas canvas) {
  //创建一个画笔实例
  Paint paint = new Paint();
  paint.setColor(Color.RED);
  //绘制文本
  canvas.drawText("Game", textX, textY, paint);
  super.onDraw(canvas);
 }
 
 @Override
 public boolean onTouchEvent(MotionEvent event) {
  //获取用户触屏的X轴赋值给文本的X坐标
  textX = (int)event.getX();
  //获取用户触屏的Y轴赋值给文本的Y坐标
  textY = (int)event.getY();
  invalidate(); 
  return true;
 }
