DatePickerDialog showing abnormal behaviour in android 5.1 when timezone is changed

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

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.

DialogFragment does not update the Display

I am new to android development and I hope you can help me solve my problem. Any help will be appreciated. I created a dialogfragment for picking dates. I am able to select the desired dates but I am having trouble in displaying the selected dates.
Here is my DialogFragment
public class DatePickerFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener {
private Calendar mCalendar;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
mCalendar = Calendar.getInstance();
int year = mCalendar.get(Calendar.YEAR);
int monthOfYear = mCalendar.get(Calendar.MONTH);
int dayOfMonth = mCalendar.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, monthOfYear, dayOfMonth);
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mCalendar.set(Calendar.YEAR, year);
mCalendar.set(Calendar.MONTH, monthOfYear);
mCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
}
and I call it from my remindersFragment which extends fragment
private void registerButtonListenersAndSetDefaultText() {
mDateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//getActivity().showDialog(DATE_PICKER_DIALOG);
android.support.v4.app.DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getFragmentManager(), "datePicker");
updateDateButtonText();
}
});
updateDateButtonText();
}
and my updateButton :
private void updateDateButtonText() {
// Set the date button text based upon the value from the database
SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_FORMAT);
String dateForButton = dateFormat.format(mCalendar.getTime());
mDateButton.setText(dateForButton);
}
I hope you can help me. I've been trying to figure this out for days but I had no luck. Thanks in advance.
Here is the full code on my DialogFragment. I hope this will help:

on tab change in same page, 2nd time OnCreate() doesn't work

All the functions are running properly, but only one problem exists that if i record details for a day, and if I switch tab to the history tab to see the new record, the viewlist in the history class should display that record. However the viewlist doesnot display the lastest record, and i check the database, the lastest record has been written into database. The only way to see the new record is to close the emulator and restart it.
I found the problem that on startup, the recorder and history tab would both be initialised in OnCreate() method. But after that when I switch between these two tabs, it would not be initialised. Therefore, in the history.class, it would not open the database and read the data. That's the problem. Could somebody please help me, thanks

Try this code and let me know whether this works for you because this solution is working for me and one of my application does have it.

My child Activity does not send result back to parent

I am attempting to create a ToDo list for a class that I am in, and how I have the app is that I have an EditText on top to enter an item in the TDL. and then I am using an extended tablelayout to display the items. I also have a button that calls to a second activity that then has 2 other buttons to get the time and date to (hopefully) display on the TDL item after I hit the Done button on the button (where I would like to go back to the main activity) So far I am testing this on an AVD.
So what I think my issue is that I dont think my second activity is passing back the info that I want. According to the debugger, the onActivityResults method from the first one gets called earlier than the second activity gets called.
Here is the first Activity:
package com.parrishb.todo;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.view.KeyEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.Button;
public class ToDoActivity extends Activity {
SharedPreferences pref;
public final static int ACTIVITY =1;
public static Globals g;
public ToDoView tdv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_to_do);
final EditText myEditText = (EditText)findViewById(R.id.myEditText);
Button mPickDate = (Button) findViewById(R.id.pickDate);
tdv = (ToDoView)findViewById(R.id.tdv);
myEditText.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getAction()== KeyEvent.ACTION_DOWN){
if((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) || (keyCode == KeyEvent.KEYCODE_ENTER)){
tdv.addRow(ToDoActivity.this, myEditText.getText().toString());
myEditText.setText("");
return true;
}
}
return false;
}
});
// CLick listener for the date/time button
mPickDate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivityForResult(new Intent(ToDoActivity.this, DatePickerActivity.class), ACTIVITY);
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(resultCode== RESULT_OK && requestCode== ACTIVITY){
String append= (new StringBuilder().append(data.getStringExtra("Time"))
.append(" ").append(data.getStringExtra("Date")).toString());
tdv.editRow(ToDoActivity.this, append);
}
}
}
Here is my second activity:
package com.parrishb.todo;

mTimeDisplay = (TextView) findViewById(R.id.time);
mPickTime = (Button) findViewById(R.id.timepicker);
done = (Button)findViewById(R.id.done);
//Pick time's click event listener
mPickTime.setOnClickListener(new View.OnClickListener(){

}
});

DatePickerActivity.this.finish();
}
});
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);

}
#Override

super.finish();
}
//-------------------------------------------update date----------------------------------------//

.append(mYear).append(" "));
}
//-------------------------------------------update time----------------------------------------//
public void updatetime()
{
mTimeDisplay.setText(
new StringBuilder()
.append(pad(mhour)).append(":")
.append(pad(mminute)));
}
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
//Datepicker dialog generation
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDate();
}
};
// Timepicker dialog generation
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mhour = hourOfDay;
mminute = minute;
updatetime();
}
};
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,
mDateSetListener,
mYear, mMonth, mDay);
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mhour, mminute, true);
}
return null;
}
}

I had scratched the second activity and brought the date and time picker into the main activity.

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.
