如何获取另一个片段中EditText中TimePickerDialog的时间？

Question

我正在尝试将我的 TimePickerDialog 的时间转换为 FinishPostFragment 中的 EditText。

我现在正在 Toast 中显示选定的时间，但如何在 FinishPostFragment 中显示 EditText 中的数据？

我的 onCreateView 中的 FinishPostFragment：

timeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // view TimePickerDialog
            showTimeDialog(v);
        }
    });

我的 onCreateView 外的 FinishPostFragment：

public void showTimeDialog(View v){
    TimeDialogFragment tdf = new TimeDialogFragment();
    tdf.show(getFragmentManager().beginTransaction(), "TimePickerFragment");
}

TimePickerDialog.OnTimeSetListener test = new TimePickerDialog.OnTimeSetListener(){
    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        time_finish.setText(String.valueOf(hourOfDay) + ":" + String.valueOf(minute));
    }
};

TimeSettings.java:

public class TimeSettings implements TimePickerDialog.OnTimeSetListener {
    Context context;

    public TimeSettings(Context context){
        this.context = context;
    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        Toast.makeText(context, "Selected time is hour: " +hourOfDay+ " minute: " + minute, Toast.LENGTH_LONG).show();
    }
}

TimeDialogFragment:

public class TimeDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
        Calendar calendar = Calendar.getInstance();

        int hour = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);

        TimePickerDialog dialog;

        TimeSettings timeSettings = new TimeSettings(getActivity());
        dialog = new TimePickerDialog(getActivity(), timeSettings, hour, minute,
                android.text.format.DateFormat.is24HourFormat(getActivity()));

        return dialog;
    }
}

Answer 1

以下内容与您所拥有的可能有效。让您的 FinishPostFragment 实现 TimePickerDialog.OnTimeSetListener 本身。

使用 getChildFragmentManager() 显示 TimeDialaogFragment。

tdf.show(getChildFragmentManager().beginTransaction(), "TimePickerFragment");

这样就可以了，然后您可以在 TimeDialogFragment.onCreateView 中执行以下操作，将所选时间直接发送到 FinishPostFragment。

TimePickerDialog.OnTimeSetListener timeSetListener = 
        (TimePickerDialog.OnTimeSetListener) getParentFragment();

dialog = new TimePickerDialog(getActivity(), timeSetListener, hour, minute,
        android.text.format.DateFormat.is24HourFormat(getActivity()));

请注意，要使用 getParentFragment()，您必须使用支持库或针对 API 17+。

Answer 2

@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

Toast.makeText(context, "Selected time is hour: " +hourOfDay+ " minute: " + minute, Toast.LENGTH_LONG).show();
String time = "   "+hourString+"h"+minuteString+"m"+secondString+"s";
    yourTextView.setText(time);

}

像这样尝试将文本设置到您的文本视图。
