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);
}

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() {

}
});
return rootView;
}
private void showDate(int year, int month, int day) {

.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

I need to pass data from Activity "MainCalendar" to fragment "AddTaskFragment" in Activity "Add". I have a button in a fragment which opens an Activity "MainCalendar", where I select a date in the calendar, and then I need to send this date into a fragment.
When I click on Choose Button, there is opens a MainCalendar, where user need to choose date, after that, the activity closed, and than I want to put a date from MainCalendar to the text of "Choose Button".

There are two ways to do that.
The first one is using callback and the second one is using a bundle.
In the first-way, you can create an interface and implement in your fragment and pass it to your activity. when users click the date you callback the parameter using this interface.
The second-way using bundles like this.
in your fragment create a constructor like this and call it in your activity :
public static YourFragment getInstance(obj yourParameter){
Bundle bundle = new Bundle();
bundle.putString("edttext", "From Activity");
// set Fragmentclass Arguments
YourFragment fragobj = new YourFragment ();
fragobj.setArguments(bundle);
return fragobj;
}
in the onCreate method get obj in this way :
String strtext = getArguments().getString("edttext");

Button btn = (Button) findViewById(R.id.datepick);
Button btn2 = (Button) findViewById(R.id.timepick);
// TextView textview = (TextView) findViewById(R.id.textView1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
DialogFragment dFragment = new DatePickerFragment();
// Show the date picker dialog fragment
dFragment.show(getFragmentManager(), "Date Picker");
}
});
btn2.setOnClickListener(new View.OnClickListener() {

// Show the time picker dialog fragment
dFragment.show(getFragmentManager(),"Time Picker");
}
});

I need year,month,day in TimePickerFragment method.Please solve it asap.Thanks in advance.
I am just getting into android apps and now trying to work with an interface that allows the user to enter time into a text box. The time picker dialog will display when a text box is focused. But now when I click the text box, the date picker dialog does not display.
WorkDetails.java
public void onFocusChange(View v, boolean hasFocus) {
EditText txtTime = (EditText) findViewById(R.id.editText6);
txtTime.setOnFocusChangeListener(new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus)
{
TimePick time = new TimePick(v);
FragmentTransaction ft = getFragmentManager().beginTransaction();
time.show(ft, "TimePicker");
}
}
});
}
TimePick.java
#SuppressLint("ValidFragment")
public class TimePick extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
private TextView time;
public TimePick(View view)
{
time=(EditText)view;
}
public Dialog onCreateDialog(Bundle savedInstanceState)
{
final Calendar c= Calendar.getInstance();
int hour=c.get(Calendar.HOUR_OF_DAY);
int minute=c.get(Calendar.MINUTE);
//Toast.makeText(getActivity(),this,"Date: "+year+"-",+month+"-"+day,Toast.LENGTH_SHORT).show();
return new TimePickerDialog(getActivity(),this,hour,minute, DateFormat.is24HourFormat(getActivity()));
}
public void onTimeSet(TimePicker view,int hourofDay, int minute)
{
time.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
}
}
editText = (EditText)findViewById(R.id.editText);

editText2.setOnFocusChangeListener(new View.OnFocusChangeListener()

{
String input;
EditText editText;
if(!hasFocus)
{
TimePick time = new TimePick(v);

try to set android:clickable="true" and android:focusableInTouchMode="false" in xml file.
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
}
};
