你遇到什么问题？

你不说错误 让大家猜？把你错误信息帖出来

报什么错，贴出来看看

[静默加载]

public void onChronometerTick(Chronometer chronometer) {
      String time = chronometer.getText().toString();
      if (time.equals("00:00")) {
            Toast.makeText(MainActivity.this, "时间到了~", Toast.LENGTH_SHORT).show();
      }
}

第一个地方，最好将“00:00”这个常量放在前面，其实更好的是用TextUtils.equals进行判断。

int point = Integer.parseInt(currentPoint);

第二个地方，Integer.parseInt特别容易抛NumberFormatException异常，这个需要进行catch。

这是让大家找错呢，哈哈哈，厉害了楼上的
