I am attempting to set the Date/Time the user selects from a Lollipop Date/Time Picker. The issue I am having is the date/time will set to the Button Text no problem. The problem is that it won't save in the string that it is in. I then want to use that string for something I know how to do.
DATEPICKER CLASS
public class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);
Date d = new Date(year, month, day);
SimpleDateFormat sdf = new SimpleDateFormat("EE, MMM dd, yyyy");
// String newDate = sdf.format(d);
Toast.makeText(getActivity(), mMonth, Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), mDay, Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), mYear, Toast.LENGTH_LONG).show();
}
}
FRAGMENT CLASS
public class Request extends Fragment {
public TextView mCurrentUser;
public Button Request_Button;
public Button RButton_Date;
public Button RButton_Time;
public String cug;
public String cu;
public String time;
public String date;
//Request newInstance()
public static Request newInstance() {
Request fragment = new Request();
return fragment;
}
//Needed empty Request Constructor
public Request() {
}
//Public onCreateView
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Make a view
View rootview = inflater.inflate(R.layout.fragment_request, container, false);
//Where you would initialize your variables
RButton_Date =(Button)rootview.findViewById(R.id.Request_Button_Date);
RButton_Time =(Button)rootview.findViewById(R.id.Request_Button_Time);
Request_Button = (Button)rootview.findViewById(R.id.Request_Button_Request);
//Current User Logged In
this.mCurrentUser = (TextView)rootview.findViewById(R.id.Current_User_TV);
date = new SimpleDateFormat("EE, MMM dd, yyyy").format(new Date().getTime());
time = new SimpleDateFormat("h:mm a" ).format(new Date().getTime());
RButton_Time.setText(time);
RButton_Date.setText(date);
//Showing current user
final ParseUser mCurrentUser = ParseUser.getCurrentUser();
if(mCurrentUser == null){
String mCurUserNull = "No User Logged on";
this.mCurrentUser.setText(mCurUserNull);
}
else{
cu = mCurrentUser.get("FirstName").toString();
cug = String.format("Hi! %s do you need a technician today?", cu);
this.mCurrentUser.setText(cug);
}
//=================================================================
//Create Dialog
RButton_Date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Do Stuff
DialogFragment picker = new DatePickerFragment();
picker.show(getFragmentManager(), "datePicker");
}
});
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
}
};
RButton_Time.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DialogFragment picker1 = new TimePickerFragment();
picker1.show(getFragmentManager(), "timePicker");
}
});
Request_Button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Write Code for Gathering Variables and sending request email!!!
//Gather user info
//Populate email
//Send Username Request to [email protected]
Toast.makeText(getActivity(), cu + " Requested a tech at "+time
+", on "+date, Toast.LENGTH_SHORT).show();
}
});
//return rootview
return rootview;
}
I don't understand what it is I am doing wrong. It produces error of Resources unknown. I have googled, searched Stackoverflow extensively. Everything from 2014 and older just doesn't work.
GOAL
I just want to get date/time selected by user to be used as a string that can be set to text inside a button. I am using the example code from Google .
EDIT
ONDATESET
public void onDateSet(DatePicker view, int year, int month, int day) {
Button DateButton = (Button) getActivity().getWindow().getDecorView().getRootView().findViewById(R.id.Request_Button_Date);
String stringDueDateFrag = (month+1) + "/" + day + "/" + year + " ";
DateButton.setText(stringDueDateFrag);
// Set up a Calendar object to capture the user selected date in case the user wants
// edit the date later. Put the user selected date in a Bundle for onCreateDialog function to use.
}
ONTIMESET
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Button TimeButton = (Button) getActivity().getWindow().getDecorView().getRootView().findViewById(R.id.Request_Button_Date);
String stringDueDateFrag = hourOfDay + ":" + minute;
TimeButton.setText(stringDueDateFrag);
}

WORKING SOLUTION
I have figured out how to get this working flawlessly.
You need to make sure you make a separate class for both Time/Datepickers. However, don't use "implements OnDateSetListener" instead just leave the class the way it is or remove that, and implement OnDateSetListener in the activity/fragment you want to use it in.
You can combine both in this way:
implements OnDateSetListener, OnTimeSetListener...
that will allow both to be used, but you must implement the needed methods. Then your good to go.
Make sure you initialize everything properly, and place everything where it needs to be programmatically.
