the above code is full fragment code with gialog innerclass too. im a beginner can you gys help me out of it?
and actually what i need is i have to click the from and to area in tab view fragment. after slecting it opens a dialog with search filter and listview. after clicking any list item it should diaplay in textview on parent fragment and after that i should be able wo pass the value to next fragment using put intent method.
currently im getting null value when i pass it to the next fragment.
i dont know why.
i have attached an image to get you the clear view. please check it.see here

How to use onSavedInstanceState with widgets?

I'm learning about screen rotation for an App, I came across this example and I tried it.
My issue is that when I try this with a Button widget, it's text is still blank. When the button is clicked a date picker dialog appears to pick a date. But if the screen is rotated after the selection is made, the previously selected date is lost.
This is my code:
startDate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setDate(startDate);
}
});
public void setDate(final Button B)
{
final Calendar calender = Calendar.getInstance();
day = calender.get(Calendar.DAY_OF_MONTH);
month = calender.get(Calendar.MONTH);
year = calender.get(Calendar.YEAR);
DatePickerDialog pickDate = new DatePickerDialog(add_event.this, new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
calender.set(i,i1,i2);
SimpleDateFormat dateFormat1 = new SimpleDateFormat("dd-MM-yyyy");
String dateString = dateFormat1.format(calender.getTime());
B.setText(dateString);
}
},year,month,day);
pickDate.show();
}
#Override
public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) {
super.onSaveInstanceState(outState, outPersistentState);
outState.putString("startDate", startDate.getText().toString());
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
startDate.setText(savedInstanceState.getString("startDate"));
}
Here are some images:

Try using the version of onSaveInstanceState(Bundle outState) with just one argument. The other is for when you have an attribute set in the manifest for the activity to persist across reboots.

showDialog not displayed Android

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() {

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() {
}
#RequiresApi(api = Build.VERSION_CODES.N)
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_fragment5, container, false);
dateView = (TextView) rootView.findViewById(R.id.textView3);
calendar = Calendar.getInstance();
year = calendar.get(Calendar.YEAR);
month = calendar.get(Calendar.MONTH);
day = calendar.get(Calendar.DAY_OF_MONTH);
showDate(year, month+1, day);
dateView.setOnClickListener(new View.OnClickListener() {
#SuppressWarnings("deprecation")
public void onClick(View v) {
dateFragment = new DatePickerFragment();
dateFragment.show(getFragmentManager(), "datePicker");
}
});
return rootView;
}
private void showDate(int year, int month, int day) {
dateView.setText(new StringBuilder().append(day).append("/")
.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

Time/Date dialog. trying to add button. Eclipse Android

So I made an Activity with textViews, editTexts, date dialog and time dialog picker. plus a button.
I used this to get the Date/Time dialogs to work:

}
Now I would some how like to get this in there so I can have a button that transferes info from the editTexts:
EditText inputName;
EditText inputRoom;
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rainbowbook);
inputName = (EditText) findViewById(R.id.editText1);
inputRoom = (EditText) findViewById(R.id.editText2);
Button btnNextScreen = (Button) findViewById(R.id.button3);
//Listening to button event
btnNextScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Starting a new Intent
Intent nextScreen = new Intent(getApplicationContext(), BookingsActivity.class);
//Sending data to another Activity
nextScreen.putExtra("name", inputName.getText().toString());
nextScreen.putExtra("room", inputRoom.getText().toString());
Log.e("n", inputName.getText()+"."+ inputRoom.getText());
startActivity(nextScreen);
}
});
}
I cant seem to figure this out and am hoping someone can help me. Thanks.

BookingsActivity:
public class BookingsActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bookings);
TextView Name = (TextView) findViewById(R.id.textView2);
TextView Room = (TextView) findViewById(R.id.textView3);
Button btnClose = (Button) findViewById(R.id.btnClose);
Intent i = getIntent();
// Receiving the Data
String name = i.getStringExtra("name");
String room = i.getStringExtra("room");
Log.e("Bookings", name + "." + room);
// Displaying Received data
Name.setText(name);
Room.setText(room);
// Binding Click event to Button
btnClose.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Closing SecondScreen Activity
finish();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_bookings, menu);
return true;
}
}

maybe this in your BookingActivity
Bundle b = i.getExtras();
String name = b.getString("name", "default name");
String room = b.getString("room", "default room");
edit:
also, launche BookingActivity with startActivityForResult() so you can get data back from it later when you're done with it.
EDIT:
examples of startActivityForResult can be found How to return a result (startActivityForResult) from a TabHost Activity? and http://android.rahulblogs.com/android-startactivityforresult-example/

TimePicker Dialog

I'm using multiple textviews with onclick listeners that direct me to a TimePicker Dialog.
However I cannot seem to know how to write the code after reading the tutorials,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
To show the dialog:
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mHour, mMinute, true);
}
return null;
}
and finally,
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
mHour = hourOfDay;
mMinute = minute;
}
};
now, to .setText for the textview that CALLED the timepicker after the TimePickerDialog.OnTimeSetListener callback, how should I write the code?
The answer is very simple but I lack OOP knowledge and still learning.
Thanks...

You need to use a global varible. say,String fromWhere="";
now,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview1";
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview2";
showDialog(TIME_DIALOG_ID);
}
});
...
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
if(fromWhere.equals(textview1))
// set hour and minute to according variable and textview
else if(fromWhere.equals(textview2))
// set hour and minute to according variable and textview
.. //so on for others
//mHour = hourOfDay;
//mMinute = minute;
fromWhere="";
}
};

create a member variable (say int whichViewClicked = 0) in your class to keep track of the textview clicked to bring-up the time-picker.
Now if you click textview1 set whichViewClicked = 1, if textview2 is clicked set whichViewClicked = 2 and so on. In the onTimeSet() method check the value of whichViewClicked and set the textview text accordingly

Use EditText and we can get time pikker long press on edit text.
EditText timeDisplay=(EditText)findViewById(R.id.timeDisplay);
timeDisplay.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
