Question

我的活动有以下法典。

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // set time picker values
    TimePicker picker = (TimePicker) findViewById(R.id.startTimePicker);

    picker.setIs24HourView(true);

    picker.setCurrentHour(10);
    picker.setCurrentMinute(15);        
}

So a time picker is set to a fixed time, this works as expected. But when I rotate the screen and the activity get s recreated the time picker show in all fields the same value - not the value set. This happens on one, two or more time pickers on screen.

是否有人解释这种令人厌恶的行为?

很显然,当你在>>><>>>>打电话到onResume()时,这个问题就得到解决。

This is really weird as onCreate gets also called on rotate and methods are hit, but there must be some logic of the control itself called which causes that.

因此,这里是“固定”:

@Override
protected void onResume()
{
     super.onResume();
     TimePicker picker = (TimePicker) findViewById(R.id.startTimePicker);

     picker.setCurrentMinute(10);
     picker.setCurrentHour(12);
}
