showDialog not displayed Android

Inside an Activity, I am calling different fragments , I want the user to be able to change the date by clicking on a textView that displays the current date, the showDialog does not want to be displayed.
dateView.setOnClickListener(new View.OnClickListener() {
#SuppressWarnings("deprecation")
public void onClick(View v) {
getActivity().showDialog(999);
}
});
Android Studio tells me that CreateDialog is never used.
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
if (id == 999) {
return new DatePickerDialog(getContext(),
myDateListener, year, month, day);
}
return null;
}

Since,
Callback for creating dialogs that are managed (saved and restored) for you by the Activity.
Implement this method in Activityinstead of Fragment
#Override
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
if (id == 999) {
return new DatePickerDialog(getContext(),
myDateListener, year, month, day);
}
return null;
}
Call Fragment like this;
private void showDate(int year, int month, int day) {
StringBuilder abbes = new StringBuilder().append(day).append("/")
.append(month).append("/").append(year);
if(fragment instanceof Fragment4){
((Fragemnt4)fragment).dateView.setText(""+abbes);
}
}
Make dateView public

showDialog() is deprecated. Replace this code
public class Fragment5 extends android.support.v4.app.Fragment {
private DatePicker datePicker;
private Calendar calendar;
private TextView dateView;
TimePicker timePicker2;
private int year, month, day;
DialogFragment dateFragment;
public Fragment5() {
}
#RequiresApi(api = Build.VERSION_CODES.N)
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_fragment5, container, false);
dateView = (TextView) rootView.findViewById(R.id.textView3);
calendar = Calendar.getInstance();
year = calendar.get(Calendar.YEAR);
month = calendar.get(Calendar.MONTH);
day = calendar.get(Calendar.DAY_OF_MONTH);
showDate(year, month+1, day);
dateView.setOnClickListener(new View.OnClickListener() {
#SuppressWarnings("deprecation")
public void onClick(View v) {
dateFragment = new DatePickerFragment();
dateFragment.show(getFragmentManager(), "datePicker");
}
});
return rootView;
}
private void showDate(int year, int month, int day) {
dateView.setText(new StringBuilder().append(day).append("/")
.append(month).append("/").append(year));
}
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) {
showDate(year,month,day);
}
} }

What exactly showDialog (int id) method does is show a dialog managed by activity. A call to onCreateDialog(int, Bundle) will be made with the same id the first time this is called for a given id. From thereafter, the dialog will be automatically saved and restored.
You must write your onCreateDialog method in Activity as said by #Burhanuddin Rashid but that could cause complexity in data transition between Activity and Fragment.
Further,
void showDialog (int id)
This method was deprecated in API level 13.
Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.
PS,
I recommend you to use a DialogFragment

helpme for TimePickerDialog and date now

I am using a button which shows the hour and minute of the team with this method
private void obtenerFechaActual() {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
}
btnSelectTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Show the TimePickerDialog
obtenerFechaActual();
showDialog(TIME_DIALOG_ID);
}
});
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mHour, mMinute, false);
}
return null;
}
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int min) {
hour = hourOfDay;
minute = min;
btnSelectTime.setText("Time selected :"+hour+"-"+minute);
}
};
It does well, but every time I press the button,it keeps the minutes and the date of the first click of the button. The idea is that every time you click the button, it displays the current time and date.

add this method:
#Override
protected void onPrepareDialog(int id, Dialog dialog) {
switch (id) {
case TIME_DIALOG_ID:
((TimePickerDialog) dialog).updateTime(mHour, mMinute);
break;
case DATE_DIALOG_ID:
((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);
break;
}
}

ShowDialog in Fragment for DateTimePickerDialog

I am trying to follow along this tutorial: http://www.learn-android-easily.com/2013/01/using-timepickerdialog-and.html
However, showDialog cannot be resolved because I am using a fragment. How can I use a DateTime Picker Dialog inside of a class that extends a fragment?
Thanks.
EDIT: Show code:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.date_and_time_picker);
// get the references of buttons
btnSelectDate=(Button)findViewById(R.id.buttonSelectDate);
btnSelectTime=(Button)findViewById(R.id.buttonSelectTime);
// Set ClickListener on btnSelectDate
btnSelectDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Show the DatePickerDialog
showDialog(DATE_DIALOG_ID);
}
});
// Set ClickListener on btnSelectTime
btnSelectTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Show the TimePickerDialog
showDialog(TIME_DIALOG_ID); //not resolved in fragment
}
});
}

This is working for me in a fragment
Time currDate = new Time(Time.getCurrentTimezone());
currDate.setToNow();
DatePickerDialog d = new DatePickerDialog(this, datePickerListener,
currDate.year, currDate.month, currDate.monthDay);
d.show();
private DatePickerDialog.OnDateSetListener datePickerListener =
new DatePickerDialog.OnDateSetListener()
{
public void onDateSet(DatePicker view, int selectedYear, int selectedMonth, int selectedDay)
{
// Do as you need
}
};

TimePicker Dialog

I'm using multiple textviews with onclick listeners that direct me to a TimePicker Dialog.
However I cannot seem to know how to write the code after reading the tutorials,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
To show the dialog:
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mHour, mMinute, true);
}
return null;
}
and finally,
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
mHour = hourOfDay;
mMinute = minute;
}
};
now, to .setText for the textview that CALLED the timepicker after the TimePickerDialog.OnTimeSetListener callback, how should I write the code?
The answer is very simple but I lack OOP knowledge and still learning.
Thanks...

You need to use a global varible. say,String fromWhere="";
now,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview1";
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview2";
showDialog(TIME_DIALOG_ID);
}
});
...
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
if(fromWhere.equals(textview1))
// set hour and minute to according variable and textview
else if(fromWhere.equals(textview2))
// set hour and minute to according variable and textview
.. //so on for others
//mHour = hourOfDay;
//mMinute = minute;
fromWhere="";
}
};

create a member variable (say int whichViewClicked = 0) in your class to keep track of the textview clicked to bring-up the time-picker.
Now if you click textview1 set whichViewClicked = 1, if textview2 is clicked set whichViewClicked = 2 and so on. In the onTimeSet() method check the value of whichViewClicked and set the textview text accordingly

Use EditText and we can get time pikker long press on edit text.
EditText timeDisplay=(EditText)findViewById(R.id.timeDisplay);
timeDisplay.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});

problems with date picker in an android app

hi i my app i have placed two edit text boxes, when i touch on it the date picker dialog box gets appeared.
Now the problem is when i touch the first edit box the dialog opens and after setting it displays at the EditText1. Then when i touch the second edit box the dialog opens and after setting some other date, it is not displayed in EditText2, instead it is show in the EditText1 and the former date gets changed
I want the dates to be displayed in respective boxes.
The following is my code
{
et1 =(EditText)findViewById(R.id.widget29);
et1.setHint("DOB");
et2 =(EditText)findViewById(R.id.widget32);
et2.setHint("DOF");
et1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
showDialog(DATE_DIALOG_ID);
}
});
et2.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
showDialog(DATE_DIALOG_ID);
}
});
// get the current date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
}
private void updateDisplay()
{
this.et1.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("-")
.append(mDay).append("-")
.append(mYear).append("-"));
}
private void updateDisplay1()
{
this.et2.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("-")
.append(mDay).append("-")
.append(mYear).append("-"));
}
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener()
{
public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth)
{
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
private DatePickerDialog.OnDateSetListener mDateSetListener1 = new DatePickerDialog.OnDateSetListener()
{
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay1();
}
};
#Override
protected Dialog onCreateDialog(int id)
{
switch (id)
{
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
}
return null;
}
}
the following are some more problems i am facing here,
Whenever i touch the edit text box the keyboard also gets opened how to hide the keyboard
in the EditText box i want the order to be viewed as Year/Month/Date
Is there any way to change the date picker dialog box as the below figure
please help me in this

Check this code..
public class Main extends Activity {
EditText et1,et2;
static final int DATE_DIALOG_ID = 0;
static final int DATE_DIALOG_ID1 = 1;
private int mYear;
private int mMonth;
private int mDay;
private int mYear1;
private int mMonth1;
private int mDay1;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
et1=(EditText)findViewById(R.id.EditText01);
et2=(EditText)findViewById(R.id.EditText02);
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
et1.setText("month/year");
et2.setText("month/year");
et1.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
showDialog(DATE_DIALOG_ID);
return false;
}
});
et2.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
showDialog(DATE_DIALOG_ID1);
return false;
}
});
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
mDay);
case DATE_DIALOG_ID1:
return new DatePickerDialog(this, mDateSetListener1, mYear1, mMonth1,
mDay1);
}
return null;
}
// updates the date in the TextView
private void updateDisplay() {
et1.setText(new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("-").append(mYear));
}
private void updateDisplay1() {
et2.setText(new StringBuilder()
// Month is 0 based so add 1
.append(mMonth1 + 1).append("-").append(mYear1));
}
// the callback received when the user "sets" the date in the dialog
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
private DatePickerDialog.OnDateSetListener mDateSetListener1 = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year1, int monthOfYear1,
int dayOfMonth1) {
// TODO Auto-generated method stub
mYear1 = year1;
mMonth1 = monthOfYear1;
mDay1 = dayOfMonth1;
updateDisplay1();
}
};
}

You're setting the same id for both show dialog methods...
et1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
showDialog(DATE_DIALOG_ID);
}
});
et2.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
showDialog(DATE_DIALOG_ID);
}
});
...and your switch/case block only has one 'case'....
switch (id)
{
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
}
As for the other issues, split them into separate questions.
