POFragment UI not updated when calling method from Activity
text
Body
copied!<p>I have an activity class CreateEventPage, this basically calls a fragment in the onCreate method which loads the form for creating a event. On pressing a particular button, the showMapFragment() method is called which replaces this fragment with MyMapFragment object (extending the Fragment class) .</p> <p>CreateEventPage class is as follows :</p> <pre><code>public class CreateEventPage extends FragmentActivity implements MapLongPressListener { private CreateEventFragment eventFragment; private MyMapFragment mapFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragmentcontainer); eventFragment = new CreateEventFragment(); getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, eventFragment).commit(); // Check whether the activity is using the layout version with // the fragment_container FrameLayout. If so, we must add the first fragment } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.create_event_page, menu); return true; } public void showTimePickerDialog(View v) { DialogFragment newFragment = new TimePickerFragment(); newFragment.show(getSupportFragmentManager(), "timePicker"); } public void showDatePickerDialog(View v) { DialogFragment newFragment = new DatePickerFragment(); newFragment.show(getSupportFragmentManager(), "datePicker"); } public void showMapFragment(View v) { // If the frag is not available, we're in the one-pane layout and must swap frags... // Create fragment and give it an argument for the selected article mapFragment = new MyMapFragment(); FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.fragment_container, mapFragment); transaction.addToBackStack(null); transaction.commit(); } @Override public void MapLongPressed(String locationAddress, double latitude, double longitude) { FragmentTransaction trans = getSupportFragmentManager().beginTransaction(); trans.replace(R.id.fragment_container, eventFragment).commit(); eventFragment.initPositions(locationAddress, latitude, longitude); } } </code></pre> <p>when i call the initPositions method of the eventFragment object , I try and update a EditText object's text field. However, the UI does not get updated. I have tried running the method on UI thread as well, it still doesn't update. view is a global variable which stores the View object returned by onCreateView method of the fragment. The initPositions method is as follows:</p> <pre><code>public void initPositions( String address, double lat, double longi) { EditText location = (EditText) view.findViewById(R.id.LocationText); latitude = lat; longitude = longi; location.setText(address); Log.i("Init Positions", address); Log.i("Init Positions", ""+latitude); Log.i("Init Positions", ""+longitude); Log.i("Init Positions", inputLocation.getText().toString()); } </code></pre> <p>However, in spite of all this, the UI does not get updated even though the log prints the correct values as I desire. Can you please tell me what I am doing wrong?</p> <p>Thanks, Rohit</p>
