How to get radio button pop up when two date pickers have same date?

I am working on a simple app in which i have taken two date pickers they subtract two dates and display the result. But i want that if the two dates are same like 06/04/2017 then two radio button should pop up for selecting full day and half day as soon as it calculates that the two dates are same.
how to do that?
public class Leave extends AppCompatActivity {

//TextView setDay;
private DatePickerDialog datePickerDialog2;

SimpleDateFormat and wrong dates

I had already tried the first two suggestions below, but I tried again and sincerely thanks for the help! The result is the same though. I´ll just edit the post to add more code info.
Hello there! I´m experimenting with a simple ToDo application and managed to change almost everything I wanted besides the date formatted that´s displayed once the user saves the task.
The task itself is added via the AddToDoActivity class which has the following resumed code:

Here´s the ToDoItem, that actually reads the info from AddToDoActivity:

}

}
public void setTitle(String title) {

}

}
public void setPriority(Priority priority) {

}
public Status getStatus() {
return mStatus;
}
public void setStatus(Status status) {

}
public Date getDate() {

}
public void setDate(Date date) {
mDate = date;
}
// Take a set of String data values and
// package them for transport in an Intent
public static void packageIntent(Intent intent, String title,
Priority priority, Status status, String date) {
intent.putExtra(ToDoItem.TITLE, title);
intent.putExtra(ToDoItem.PRIORITY, priority.toString());
intent.putExtra(ToDoItem.STATUS, status.toString());
intent.putExtra(ToDoItem.DATE, date);
}
public String toString() {
return mTitle + ITEM_SEP + mPriority + ITEM_SEP + mStatus + ITEM_SEP
+ FORMAT.format(mDate);
}
public String toLog() {
return "Title:" + mTitle + ITEM_SEP + "Priority:" + mPriority
+ ITEM_SEP + "Status:" + mStatus + ITEM_SEP + "Date:"
+ FORMAT.format(mDate);
}
}
Oh well, after hours tweaking the
public final static SimpleDateFormat FORMAT = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss", Locale.US);
method from ToDoItem, I still cannot successfully convert yyyy-MM-dd to dd/MM/yyyy.
First, I´ve tried the obvious, and changed the expression yyyy-MM-dd to dd/MM/yyyy.
After that, all I got after saving the task was today´s date, even though the date inputted on AddToDoActivity is months or years ahead. If I revert back to yyyy-MM-dd, the date shown on the Task List is the same inputted on AddToDoActivity.
Then I tried to change all mentions of dates on every class to match the exact format that I wanted.
That made everything look good on AddToDoActivity, but again, when I transported the date back to ToDoItem, the app just ignored the previously inputted date and showed today´s date again.
Can anyone help me with this one??
Thanks!!

You are calling setDateString with arguments in the order of year, month, day:
setDateString(c.get(Calendar.YEAR), c.get(Calendar.MONTH),
c.get(Calendar.DAY_OF_MONTH));
But your method has parameters in the order of day, month, year:
private static void setDateString(int dayOfMonth, int monthOfYear, int year) {
...
}
I also think you made some errors while copying your code into the question, since the setDateString method is duplicated and there is no setTimeString method.

Change:
setDateString(c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
to:
setDateString(c.get(Calendar.DAY_OF_MONTH), c.get(Calendar.MONTH), c.get(Calendar.YEAR));

Modify the code as follows in the ToDoListAdapter file getView method
// TODO - Display Time and Date.
// Hint - use ToDoItem.FORMAT.format(toDoItem.getDate()) to get date and time String
final TextView dateView = (TextView) itemLayout.findViewById(R.id.dateView);
dateView.setText(ToDoItem.FORMAT.format(toDoItem.getDate()));
The output will be something similar the the following

How to implement Android date picker in a fragment

I have implemented a date picker as following.
private void updateDisplay() {
String str_date = "";
if ((Month + 1) >= 10) {
if (Day < 10) {
str_date = Year + "-" + (Month + 1) + "-0" + Day;
} else {
str_date = Year + "-" + (Month + 1) + "-" + Day;
}
} else {
if (Day < 10) {
str_date = Year + "-0" + (Month + 1) + "-0" + Day;
} else {
str_date = Year + "-0" + (Month + 1) + "-" + Day;
}
}
date.setText("" + str_date);
}
protected void onPrepareDialog(int id, Dialog dialog) {
switch (id) {
case DATE_DIALOG_ID:
((DatePickerDialog) dialog).updateDate(Year, Month, Day);
break;
}
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(viewLoad.getContext(),
mDateSetListener, Year, Month, Day);
}
return null;
}
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
Year = year;
Month = monthOfYear;
Day = dayOfMonth;
updateDisplay();
}
};
Here is my code segment for button.
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btnDate:
showDialog(DATE_DIALOG_ID);
break;
This works fine. Now the problem is I need to implement a date picker in a fragment. Can anyone plz explain how to do it.
Edited Code
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
Year = year;
Month = monthOfYear;
Day = dayOfMonth;
updateDisplay();
}
};
Thanx in advance.

Use this CustomDialogFragment that contains use of
TimePicker Dialog fragment
DatePicker Dialog fragment
Simple Dialog Fragment
CustomeDialogFragment Class
public class CustomDialogFragment extends DialogFragment
{
public static final int DATE_PICKER = 1;
public static final int TIME_PICKER = 2;
public static final int DIALOG = 3;
Context mContext;
String mMessage;
boolean finishActivity;
// private Fragment mCurrentFragment;
Activity mActivity;
/**
* this constructor is used for datepicker & Timepicker
*/
public CustomDialogFragment (Fragment fragment ) {
// mCurrentFragment = fragment;
}
public CustomDialogFragment (Activity mActivity ) {
this.mActivity = mActivity;
}
/**
* this constructor is used for simple dialog fragment
*/
public CustomDialogFragment(Context context, String message, final boolean finishActivity) {
mContext = context;
mMessage = message;
this.finishActivity = finishActivity;
}
public Dialog onCreateDialog(Bundle savedInstanceState) {
Bundle bundle = new Bundle();
bundle = getArguments();
int id = bundle.getInt("dialog_id");
switch (id) {
case DATE_PICKER:
return new DatePickerDialog(getActivity(),
(OnDateSetListener)mActivity, bundle.getInt("year"),
bundle.getInt("month"), bundle.getInt("day"));
case TIME_PICKER:
return new TimePickerDialog(getActivity(),
(OnTimeSetListener)mActivity,bundle.getInt("hour"),
bundle.getInt("minute"), true);
case DIALOG:
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(mContext);
alertDialogBuilder.setTitle(R.string.app_name);
alertDialogBuilder.setMessage(mMessage);
alertDialogBuilder.setIcon(R.drawable.ic_launcher);
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setPositiveButton(
getResources().getString(R.string.ok), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int arg1) {
dialog.dismiss();
if (finishActivity == true) {
Activity act = (Activity) mContext;
act.finish();
}
}
});
alertDialogBuilder.setNegativeButton(getResources().getString(R.string.cancel_btn_title), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
CustomDialogFragment.this.dismiss();
}
});
return alertDialogBuilder.create();
}
//Define your custom dialog or alert dialog here and return it.
return new Dialog(getActivity());
}
}
& Use date Picker this Way
1) In your Activity Or fragment Implement OnDateSetListener ( after done it will get back result to onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) method)
2) Call DatePicker From Fragment Like this way
CustomDialogFragment dialog = new CustomDialogFragment(YourFragment.this);
Bundle bundle = new Bundle();
bundle.putInt("dialog_id", CustomDialogFragment.DATE_PICKER);
bundle.putInt("year", mYear);
bundle.putInt("month", mMonth);
bundle.putInt("day", mDay);
dialog.setArguments(bundle);
dialog.show(getFragmentManager(), "dialog");
& Call DatePicker From Activity(or FragmentActivity) Like this Way
CustomDialogFragment dialog = new CustomDialogFragment(this);
Bundle bundle = new Bundle();
bundle.putInt("dialog_id", CustomDialogFragment.DATE_PICKER);
bundle.putInt("year", mYear);
bundle.putInt("month", mMonth);
bundle.putInt("day", mDay);
dialog.setArguments(bundle);
dialog.setCancelable(false);
dialog.show(this.getSupportFragmentManager(), "dialog");
& as per Set "dialog_id" u can use TIME_PICKER (for time picker dialog) & DIALOG(for simple dialog)
as per send "dialog_id" according to send data through bundle to CustomDialogFragment.

As my knowledge, cannot use showDialog() in Fragment. It's also deprecated.
Use DialogFragment.

App wont run since i added a validation if statement

Hi i added this piece of code to my Android app and it suddenly stopped working(it wont start). I am trying the make sure hat the user is not allowed to proceed if a return date less then the departure date is selected.
String departureDateTemp = dYear+ ""+ ""+dMonth + ""+dDay;
int departureDateTemp2 = Integer.parseInt(departureDateTemp);
String returnDateTemp = rYear+ ""+ ""+rMonth + ""+rDay;
int returnDateTemp2 = Integer.parseInt(returnDateTemp);
if(returnDateTemp2 >= departureDateTemp2){
//MESSAGE
if(buttonR.isChecked()){
String returnDate = txR.getText().toString();
basket.putString("returnDate", returnDate);
type = "Return";
}
else{
type = "Oneway";
}
}
else{
btnSubmit.setEnabled(false);
}
My Full activity is this

How to change the content of the layout?

In my Android application i have a tracker activity in which i retrieve the exercises information(name , period , burned calories) from the sqlite data base based on the selected date and display these information in a linear layout , and my problem that as the user select new date the retrieved data are displayed in another "new " layout appear above the old one but what actually i want to do is to display the new retrieved data on the same layout " change the layout content with the new retrieved data ", i have tried the remove all views method but it didn't work since the data appear for few minutes then dis appear

Its because you defined these variables as static:
public static int icon;
public static String data_text;
public static String text;
As a result only one instance of those variables are created for all instances of that class. So when you create a new Profile each time, they are overwritten with new values. You need to remove the static keyword from variable declarations:
public int icon;
public String data_text;
public String text;
Then you cannot access them as static so you need to access like this:
Profile pli = data[position];
holder.imgIcon.setImageResource(pli.icon);
holder.Datatxt.setText(pli.data_text);
holder.txt.setText(pli.text);
