DatePickerDialog showing abnormal behaviour in android 5.1 when timezone is changed

I have to show calender using DatePickerDialog.
The below code is used:

tz = TimeZone.getDefault();
System.out.println("TimeZone "+tz.getDisplayName(false, TimeZone.SHORT)+" Timezon id :: " +tz.getID());
timeZone = tz.getDisplayName(false, TimeZone.SHORT);
// Intent intent1 = getIntent();
// finish();
// startActivity(intent1);
showDialog(DATE_PICKER_ID);
}
}
};
}
When the app is running, I go to the settings and change the Timezone to such a value so that the current date will change. Now when we select any date in the dialog, it behaves abnormally and goes to other date. I have used setMinDate() and setMaxDate() methods. This happens only in Android OS 5.1.
Any idea or help? Thanks in advance.

Getting data from a DatePickerDialog to a fragment

As above I am trying to work out how to pass back the date selected by the user. I have worked out how to get the date selected by using the onDateSet method but I do not know how to feed this back to the parent fragment, and then set the EditText text to the date selected.
package com.example.androidvehicle;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;

import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;
public class fragmentServicing extends Fragment {
callBack mCallBack;
Button mot;
Button servicing;
Button tax;
EditText txtService;
final int Date_Dialog_ID=0;
int cDay,cMonth,cYear; // this is the instances of the current date
Calendar cDate;
int sDay,sMonth,sYear; // this is the instances of the entered date
int id_dialog = 1;
int yr, day, month = 0;
// interfacing back to activity
public interface callBack
{
public void onItemSelected(String id);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_servicing, container, false);
txtService = (EditText) view.findViewById(R.id.txtServiceDate);
mot = (Button) view.findViewById(R.id.buttonMOT);
servicing = (Button) view.findViewById(R.id.buttonService);
servicing.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// this will then pass back to the activity the string hello
mCallBack.onItemSelected("hello");
getActivity().showDialog(1);
}
});
mot.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
getActivity().showDialog(1);
}
});
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// This makes sure that the container activity has implemented
// the callback interface. If not, it throws an exception
try {
mCallBack = (callBack) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnHeadlineSelectedListener");
}
}
// this is an override for when the dialog is created
protected Dialog onCreateDialog(int id)
{
switch(id)
{
// this will return a date picker dialog if 1 is passed
// could use another number for another dialog
case 1:
// passes it the current date
return new DatePickerDialog(getActivity(), mDateSetListener, yr, month, day);
}
return null;
}
// this returns the date back that has been selected by the user
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
yr = year;
month = monthOfYear;
day = dayOfMonth;
Log.d("date selected", "year "+ yr+ " month " +month+" day "+day);
}
};
}

You can set DateListner on Edittext onClicklistner..

import android.widget.TextView;
public class DateListener implements OnClickListener, OnDateSetListener {
private Activity activity;
private int year;
private int monthOfYear;
private int dayOfMonth;
private View touchedView;
public DateListener(Activity activity) {
this.activity = activity;
final Calendar c = Calendar.getInstance();
this.year = c.get(Calendar.YEAR);
this.monthOfYear = c.get(Calendar.MONTH);
this.dayOfMonth = c.get(Calendar.DAY_OF_MONTH);
}
public int getYear() {
return year;
}
public int getMonth() {
return monthOfYear;
}
public int getDay() {
return dayOfMonth;
}
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
this.year = year;
this.monthOfYear = monthOfYear + 1;
this.dayOfMonth = dayOfMonth;
updateDisplay();
updateEditText();
}
#Override
public void onClick(View v) {
touchedView = v;
new DatePickerDialog(activity,
this, this.getYear(), this.getMonth(), this.getDay()).show();
}
private void updateDisplay() {
((TextView) touchedView).setText(
new StringBuilder()
.append(pad(dayOfMonth)).append(".")
.append(pad(monthOfYear)).append(".")
.append(pad(year)));
}
private void updateEditText() {
((EditText) touchedView).setText(
new StringBuilder()
.append(pad(dayOfMonth)).append(".")
.append(pad(monthOfYear)).append(".")
.append(pad(year)));
}
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
}
In Your Fragment
DateListener dateListener = new DateListener(getActivity());
edittext.setOnClickListener(dateListener);

app ends while clicking datepicker button

My program contains a button named date to show calendar view. but app ends while clicking it. pls give me a solution.My program contains a button named date to show calendar view. but app ends while clicking it. pls give me a solution.

You are getting a Nullpointer because you never actually initialize the Calendar object:

Pass string and stringbuilder from between activities

I have two activities and I need to pass some strings and a stringbuilder from TailorThreeActivity.java to EnquireActivity.java.
After displaying the string and stringbuilder data on EnquireActivity screen, I am calling an Intent to send mail by clicking on the "Send Mail" button. The "Send Mail" button will open a mail client and will set all the string and stringbuilder data as the email message body.
I am able to display the value of stringbuilder in EnquireActivity.java, but the other strings coming from TailorThreeActivity.java are not being displayed in the activity. And although the stringbuilder is being displayed in EnquireActivity, neither the strings nor the stringbuilder are displayed in the Email msg body.

One of the main problems I see is this part of code
i1.putExtra(et_name.getText().toString(), "name");
i1.putExtra(et_adult.getText().toString(), "adults");
i1.putExtra(et_child.getText().toString(), "child");
i1.putExtra(et_email.getText().toString(), "email");
i1.putExtra(et_phone.getText().toString(), "phone");
with
getname = extras.getString("name");
getadult = extras.getString("adults");
getchild = extras.getString("child");
getmail = extras.getString("email");
getphone = extras.getString("phone");
You are not sending correclty these values because when you are using putExtra the first parameter is the key and the second is the value. That's why you are not able to retrieve them in your second activity.

Intent contains name-value pair do-correct in first activity
Intent i = new Intent();
StringBuffer sb = new StringBuffer("Hello");
i.putExtra("email", "jignesh.patel#y7mail.com");
i.putExtra("sub", sb.toString());
Send like this..
For Sending Mail Set these parameters..
String message = "Your_message"; String mail_id = "Email_id"; String
sub = "Mail Subject";
Intent mail = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" +
mail_id));
mail.putExtra(Intent.EXTRA_SUBJECT,sub);
mail.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(mail,"Mail Using"));
..it will work for you..

How to set the date from DatePicker dialog for multiple calls

Good day, can't seem to find a solution for this. i have 2 buttons that when pressed, opens a datepickerdialog, but my problem now is , how can i set them to the appropriate button on OnDateSet method. I am using a DialogFragment for the date and then implementing the DateListener in my activity. I have tried using getTag() but no success in getting the tag. here is what i tried:
public void showfromDatePickerDialog(View v) {
DialogFragment dateFragment = new DateDialogFragment();
dateFragment.show(getSupportFragmentManager(), "fromdatePicker");
}
public void showtoDatePickerDialog(View v) {
DialogFragment dateFragment = new DateDialogFragment();
dateFragment.show(getSupportFragmentManager(), "todatePicker");
}
public void onDateSet(DatePicker view, int year, int month, int day) {
StringBuilder builder = new StringBuilder();
builder.append(day).append("-")
.append(month).append("-")
.append(year);
String text= builder.toString();
if(view.getTag().toString().equals("fromdatePicker")) { // error here
Log.d(TAG, "got here" + text);
fromdate.setText(text);
}
if(view.getTag() == "todatePicker") {
todate.setText(text);
}
any ideas how to implement this? i keep seeing solutions about using 2 different DialogFragment class but am guessing there should be another way. or am i wrong? Thank you

ok, i have a work around for these. which can be helpful for anyone with this problem. if its slightly incorrect please let me know and i can change it. but this is what i did to solve this issue.
in on DateSet:
public void onDateSet(DatePicker view, int year, int month, int day) {
StringBuilder builder = new StringBuilder();
builder.append(day).append("-")
.append(month).append("-")
.append(year);
String text= builder.toString();
FragmentManager fragmanager = getSupportFragmentManager();
if(fragmanager.findFragmentByTag("fromdatePicker") != null) {
Log.d(TAG, "got here" + text);
fromdate.setText(text);
}
// if(view.getTag() == "todatePicker") {
if(fragmanager.findFragmentByTag("todatePicker") != null) {
todate.setText(text);
}
that way you can use the same dateListener for multiple calls and set the date appropriately based on the tag that was passed when calling show on the dialog.

Use below code of DatePicker Dialog.
private int mYear;
private int mMonth;
private int mDay;
Calendar cal4DatePicker = Calendar.getInstance();
Button btnDOB=findviewbyId(R.id.btndob);
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
cal4DatePicker.set(Calendar.YEAR, mYear);
cal4DatePicker.set(Calendar.MONTH, mMonth);
cal4DatePicker.set(Calendar.DAY_OF_MONTH, mDay);
btnDOB.setText(new StringBuilder()
.append(mDay).append("-").append(mMonth).append("-").append(mYear).append(" "));
}
};
on btnDOB you need to set click listner to show this DatePicker Dialog.

I have try same thing with Time Picker only. You can try out and set same for date picker also.
