TimePickerDialog应用程序崩溃时，项目在每个牛轧糖设备的 Eclipse IDE 中开发。
以下是我的代码
public class FragementMailScreen extends Fragment implements OnClickListener {
TimePickerDialog mTimePicker;
Calendar mcurrentTime;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.layout_main_screen);
mainView = inflater.inflate(R.layout.fragment_mail_screen, container,
false);
pref = new AppPreferences(getActivity().getApplicationContext());
typeface = Typeface.createFromAsset(getActivity().getAssets(),
getString(R.string.font_name));
txtTopTitle = (TextView) mainView.findViewById(R.id.txtTopTitle);
mcurrentTime = Calendar.getInstance();
getAllComponets();
return mainView;
}
private void setDriverMode() {
if (pref.getDriverMode().equals("0")) {
mainView.findViewById(R.id.mainViewMail).setBackgroundColor(
getResources().getColor(R.color.day_backcolor));
} else {
mainView.findViewById(R.id.mainViewMail).setBackgroundColor(
getResources().getColor(R.color.night_backcolor));
}
}
@Override
public void onResume() {
// registerBroadcast();
((MainScreen) getActivity()).mMailFragment = this;
super.onResume();
}
public boolean isFragmentUIActive() {
return isAdded() && !isDetached() && !isRemoving();
}
public static boolean m_iAmVisible;
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
m_iAmVisible = isVisibleToUser;
}
ListView listMessage;
private void getAllComponets() {
listMessage = (ListView) mainView.findViewById(R.id.listMessage);
if (CommonUtilities.isBeta) {
((TextView) (mainView.findViewById(R.id.btnVersion)))
.setText(getString(R.string.text_beta));
} else {

}
listMessage.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
CommonCode.gps = new GPSTracker(getActivity());
if (CommonCode.gps.isGPSEnabled) {
Messages detail = message.DriverPopupMessageResponse.LstDriverPopupMessageResponse
.get(position);
if (detail.RID == -1) {
final int RType;
// FLG false means Request Going Home
// then RType is 1 else 2
if (detail.FLG)
RType = 2;
else
RType = 1;
if (RType == 1) {
final int c_hour = mcurrentTime
.get(Calendar.HOUR_OF_DAY);
final int c_minute = mcurrentTime
.get(Calendar.MINUTE);
mTimePicker = new TimePickerDialogFixedNougatSpinner(getActivity(),R.style.SpinnerTimePicker,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(
TimePicker timePicker,
int selectedHour,
int selectedMinute) {
/* String time = selectedHour + ":"
+ selectedMinute;*/
/*new DriverGoingHome_request()
.execute(time, String
.valueOf(RType));*/
}
}, c_hour, c_minute, true)// Yes 24 hour
// time
{
@Override
public void onTimeChanged(TimePicker view,
int hourOfDay, int minute) {
/* if (hourOfDay < c_hour) {
updateTimeDialog(view, c_hour, c_minute);
} else if (hourOfDay == c_hour
&& minute < c_minute)
updateTimeDialog(view, c_hour, c_minute);*/
}
private void updateTimeDialog(TimePicker view,
int c_hour, int c_minute) {
// TODO Auto-generated method stub
view.setCurrentHour(c_hour);
view.setCurrentMinute(c_minute);
}
};
mTimePicker.setTitle("Select Time");
mTimePicker.show();
// setDividerColor(picker);
/* Button b = mTimePicker
.getButton(DialogInterface.BUTTON_POSITIVE);
if (b != null) {
b.setText("OK");
}
Button b_Neg = mTimePicker
.getButton(DialogInterface.BUTTON_NEGATIVE);
if (b_Neg != null) {
b_Neg.setText("Cancel");
}*/
/* Alert_BUTTON_NEGATIVE(mTimePicker);
Alert_BUTTON_POSITIVE(mTimePicker);
*/
} else {
String time = "";
showAlert(
time,
String.valueOf(RType),
getString(R.string.cancel_request_goingHome));
// new DriverGoingHome_request().execute(time,
// String.valueOf(RType));
}
// mTimePicker.setOnTimeChangedListener(this);
}
在上面的代码中，mTimePicker是TimePickerDialog无法正常工作的对象
