         tv_name.setOnClickListener(new View.OnClickListener()
         {
             //需要监听几次点击事件数组的长度就为几
             //如果要监听双击事件则数组长度为2，如果要监听3次连续点击事件则数组长度为3...
             long[] mHints = new long[3];//初始全部为0

                 System.arraycopy(mHints, 1, mHints, 0, mHints.length - 1);
                 //获得当前系统已经启动的时间
                 mHints[mHints.length - 1] = SystemClock.uptimeMillis();

                 Toast.makeText(getApplicationContext(),"当你点击三次之后才会出现", Toast.LENGTH_SHORT).show();
             }
