Android Touch Circle Activity触屏操作测试附源代码示例,触摸圆点:
  //此方法重画时调用
  @Override
  protected void onDraw(Canvas canvas) {
   //canvas可以看做画板
   super.onDraw(canvas);
   //创建画笔
   Paint p = new Paint();
   p.setColor(Color.RED);
   canvas.drawCircle(current_x, current_y, 5, p);
  }
  
  我们可以得到线性布局的容器,创建出自定义的View,设置自定义组建的最大宽度和最大高度,设置位置,之后开始重新画,返回true则表明已经处理了本事件。
