java - 如何获取另一个fragment中EditText中TimePickerDialog的时间？

Question

我正在尝试将 TimePickerDialog 的时间获取到 FinishPostFragment 中的 EditText。

我现在在 Toast 中显示所选时间，但如何在 FinishPostFragment 的 EditText 中显示数据？

我的 onCreateView 中的 FinishPostFragment:

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

在我的 onCreateView 之外完成 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));
    }
};

时间设置.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();
    }
}

时间对话框 fragment :

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

@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);

} 

尝试像这样将文本设置到您的 TextView 。
