Fragment isAdded() returns false on an already added Fragment

佐手、 提交于 2019-11-29 01:27:38
I have this neat function: private void addMapFragment(){ if(!mapFragment.isAdded()){ FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.add(R.id.mapContainer, mapFragment); ft.commit(); } } I'm calling addMapFragment() in my activity's onCreate() . I then have a callback from a webrequest that calls addMapMapFragment() . The isAdded() method doesn't look useful at all since I'm getting a crash saying "Fragment already added: MapFragment[...] " Any clue? FragmentTransactions are committed asynchronously . Therefore, you need to call getFragmentManager()

How is the new FragmentTransaction commitNow() working internally?

问题 The new commitNow() method added in Android N and support library version 24 has a limited and a bit confusing documentation. Commits this transaction synchronously. Any added fragments will be initialized and brought completely to the lifecycle state of their host and any removed fragments will be torn down accordingly before this call returns. Committing a transaction in this way allows fragments to be added as dedicated, encapsulated components that monitor the lifecycle state of their

问题 EDIT : If I extend FragmentActivity instead of ActionBarActivity my layout shows up again (without an ActionBar of course). The ActionBar works as intended on 4.x devices, but on my 2.3 device all I get is the ActionBar and a blank screen below it. The Fragment doesn't seem to be getting added to the Activity . themes.xml <style name="AppTheme" parent="AppBaseTheme"> <item name="actionBarStyle">@style/Widget.ActionBar</item> </style> themes-v11.xml <style name="AppTheme" parent="AppBaseTheme"

I am using the following method to switch between Fragments (in my NavigationDrawer) by showing / hiding them. protected void showFragment(int container, Fragment fragment, String tag, String lastTag, boolean addToBackStack ) { FragmentManager fragmentManager = getSupportFragmentManager(); FragmentTransaction transaction = fragmentManager.beginTransaction(); if ( lastTag != null && !lastTag.equals("")) { Fragment lastFragment = fragmentManager.findFragmentByTag( lastTag ); if ( lastFragment != null ) { transaction.hide( lastFragment ); } } if ( fragment.isAdded() ) { transaction.show( fragment

DrawerLayout's item click - When is the right time to replace fragment?

旧时模样 提交于 2019-11-28 03:06:17
I'm developing an application which uses the navigation drawer pattern (With DrawerLayout). Each click on a drawer's item, replaces the fragment in the main container. However, I'm not sure when is the right time to do the fragment transaction? When the drawer starts closing? Or after it is closed? In google's documentaion example , you can see that they are doing the transaction right after the item click, and then close the drawer. As a result, the drawer seems laggy and not smooth, and it looks very bad (It happens in my application too). In Gmail and Google Drive applications, on the other

Navigation Drawer lag on Android

I'm having a problem with Navigation Drawer , it is too slow, the solution I'm looking for is to close the drawer first and then show the activity, but It is not working, certainly I'm missing something. private class DrawerItemClickListener implements ListView.OnItemClickListener { @Override public void onItemClick(AdapterView<?> parent, View view, int posicao, long id) { setLastPosition(posicao); setFragmentList(lastPosition); layoutDrawer.closeDrawer(linearDrawer); } } private OnClickListener userOnClick = new OnClickListener() { @Override public void onClick(View v) { layoutDrawer
