Date Picker Dialog using Edittext /Using fragment datepicker dialog

Step  1 :   create  activity.xml

  <EditText android:layout_width="match_parent" 

            android:layout_height="wrap_content"   

            android:id="@+id/edttext" />

Step 2 :  Create the DatePickerFragment.class

public class DatePickerFragment extends DialogFragment

        implements DatePickerDialog.OnDateSetListener {

    DatePickerFragment mInstance;


    public interface DateListener {
        void onDateSelected(int year, int month, int day);
    }

    DateListener mDateListener;

    public void setCallBack(DateListener dateListener) {
        this.mDateListener = dateListener;
    }

    public void DatePickerFragment(DatePickerDialog.OnDateSetListener m) {
        mInstance = this;
    }

    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker       

        final Calendar c = Calendar.getInstance();
        c.add(Calendar.YEAR, -18);
        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) {
        mDateListener.onDateSelected(year, month, day);
    }


}

Step 3:    Main Activity

 ettext.setOnClickListener(new View.OnClickListener() {

    @Override    public void onClick(View v) {
        showDatePickerDialog();
    }
});

Step 4 : Main Activity

private void showDatePickerDialog() {
    DatePickerFragment newFragment = new DatePickerFragment();
   
  // newFragment.show(getSupportFragmentManager(), "datePicker");
     newFragment.show(getFragmentManager(), "datePicker");

    newFragment.setCallBack(mDateListener);
}


private DatePickerFragment.DateListener mDateListener = new DatePickerFragment.DateListener() {
       public void onDateSelected(int year, int month, int day) {

        Calendar c = Calendar.getInstance();
        c.set(year, month, day);

        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
        String formattedDate = sdf.format(c.getTime());
        ettext.setText(formattedDate);


 
     /* java.util.Calendar c = java.util.Calendar.getInstance();
            c.set(year, month, day);

            java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("dd-MM-yyyy");
            String formattedDate = sdf.format(c.getTime());
            editBirthdate.setText(formattedDate); */













    }
