我正在尝试使用timepicker对话框，但每次启动对话框时，它都会崩溃，而我似乎无法弄清楚问题。我在Android Studio中模拟的Nexus 5X API Level P上运行它。在此之前，我尝试在没有片段的情况下制作TimePicker对话框，它给了我同样的错误。我现在得到了。
编辑：意识到它适用于我的手机，但不适用于android studio中的模拟器。
TimePickerDialogFragment
public class TimePickerDialogFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{
public interface TimePickerDialogListener {
public void onTimePickerDialogTimeSet(int hour, int minute);
}
TimePickerDialogListener mListener;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Date date = new Date();
Calendar calendar = GregorianCalendar.getInstance();
calendar.setTime(date);
int currentHour = calendar.get(Calendar.HOUR_OF_DAY);
int currentMinute = calendar.get(Calendar.MINUTE);
return new TimePickerDialog(getActivity(), this, currentHour, currentMinute, true);
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mListener.onTimePickerDialogTimeSet(hourOfDay, minute);
}
}
从MainActivity调用
TextView timeEdit = (TextView)findViewById(R.id.alarmTime);
timeEdit.setText(dreamAlarm.getAlarmTimeString());
timeEdit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DialogFragment TimePickerDialogFragment = new TimePickerDialogFragment();
TimePickerDialogFragment.show(getFragmentManager(), "alarm-time-picker");
}
});
MainActivity中的接收者
@Override
public void onTimePickerDialogTimeSet(int hour, int minute) {
dreamAlarm.setAlarmTime(hour, minute);
TextView timeEdit = (TextView)findViewById(R.id.alarmTime);
timeEdit.setText(dreamAlarm.getAlarmTimeString());
}

答案 0 :(得分：0)
尝试将您的通话部分 TimePickerDialogFragment.show(getFragmentManager(), "alarm-time-picker"); 更改为低于一个。
TextView timeEdit = (TextView)findViewById(R.id.alarmTime);
timeEdit.setText(dreamAlarm.getAlarmTimeString());
timeEdit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
TimePickerDialogFragment dialogFragment = new TimePickerDialogFragment();
dialogFragment.show(getFragmentManager(), "timePicker");
dialogFragment.setListener(new TimePickerDialogFragment.TimePickerDialogListener() {
@Override
public void onTimePickerDialogTimeSet(int hour, int minute) {
//here use the time
Log.d("hour= ", hour + " minute= " + minute);
}
});
}
});
并且您的TimePickerDialogFragment应该如下所示
public class TimePickerDialogFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
private TimePickerDialogListener listener;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Date date = new Date();
Calendar calendar = GregorianCalendar.getInstance();
calendar.setTime(date);
int currentHour = calendar.get(Calendar.HOUR_OF_DAY);
int currentMinute = calendar.get(Calendar.MINUTE);
return new TimePickerDialog(getContext(), this, currentHour, currentMinute, true);
}
@Override
public void onTimeSet(TimePicker timePicker, int i, int i1) {
listener.onTimePickerDialogTimeSet(i, i1);
getDialog().dismiss();
}
public void setListener(TimePickerDialogListener listener) {
this.listener = listener;
}
/**
* listener
*/
public interface TimePickerDialogListener {
public void onTimePickerDialogTimeSet(int hour, int minute);
}
}
