android - DateFormat.getDateTimeInstance()。format(date)的工作

我对代码中date format.getDateTimeInstance（）.format（date）的工作感到困惑我正在执行以下操作：

BroadcastReceiver myReciever = new BroadcastReceiver(){
 String currentDateTimeString;
 @Override
 public void onReceive(Context context, Intent intent){
    currentDateTimeString = DateFormat.getDateTimeInstance().format(date);
    switch(prevRAT)       //somevariable
    {
        case 0:
          det1.setText(currentDateTimeString);    //det is an EditText variable
          break;
        case 1:
          det2.setText(currentDateTimeString;
          break;
        default:
          break;
    }
  }
};

控件下次进入onReceive函数时，currentDateTimeString不会更新，它显示的日期和时间值相同。我不能理解这种行为。如何获取当前时间。

最佳答案

BroadcastReceiver myReciever = new BroadcastReceiver(){
 String currentDateTimeString;
 @Override
 public void onReceive(Context context, Intent intent){
    currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
    switch(prevRAT)       //somevariable
    {
        case 0:
          det1.setText(currentDateTimeString);    //det is an EditText variable
          break;
        case 1:
          det2.setText(currentDateTimeString;
          break;
        default:
          break;
    }
  }
};
