Hy all, i have a problem with the Fragments, and i really dont know how to solve it. hopefully somebody can help me.
I have a layout for portrait mode: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:layout_width="match_parent" android:layout_height="match_parent"> <fragment class="ch.kusar.dwr.layout.OverviewFragment" android:id="@+id/overview" android:layout_width="match_parent" android:layout_gravity="bottom" android:layout_height="match_parent"/> </RelativeLayout> and a layout for landscape mode: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment class="ch.kusar.dwr.layout.OverviewFragment" android:id="@+id/overview" android:layout_width="fill_parent" android:layout_height="60dp" /> <fragment class="ch.kusar.dwr.layout.ContentFragment" android:id="@+id/content" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@+id/overview" /> </RelativeLayout> In the OverviewFragment, i have a method to show details. void showDetails(int index) { currentButton = index; if (mDualPane) { // We can display everything in-place with fragments, so update // the list to highlight the selected item and show the data. // getListView().setItemChecked(index, true); // Check what fragment is currently shown, replace if needed. ContentFragment cf = (ContentFragment) getFragmentManager() .findFragmentById(R.id.content); // /hereChanged // if (cf == null || (cf.getPressedButton() != index)) { if (cf == null || (prefs.getInt(ContentEnum.PRESSEDBUTTON.name(), 0) != index)) { // Make new fragment to show this selection. // cf = ContentFragment.newInstance(index); setPressedButton(index); // Execute a transaction, replacing any existing fragment // with this one inside the frame. FragmentTransaction ft = getFragmentManager() .beginTransaction(); ft.replace(R.id.content, cf); // /hereChanged ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); ft.commit(); } } else { // Otherwise we need to launch a new activity to display // the dialog fragment with selected text. Intent intent = new Intent(); intent.setClass(getActivity(), ContentActivity.class); // intent.putExtra("button", index); setPressedButton(index); startActivity(intent); } } and the ContentFragment onCreateView looks like this: @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { Log.e("ContentFragment.onCreateView", "onCreateView"); // TODO Auto-generated method stub if (container == null) { // // We have different layouts, and in one of them this // // fragment's containing frame doesn't exist. The fragment // // may still be created from its saved state, but there is // // no reason to try to create its view hierarchy because it // // won't be displayed. Note this is not needed -- we could // // just run the code below, where we would create and return // // the view hierarchy; it would just never be used. //return null; } if (prefs.getInt(ContentEnum.PRESSEDBUTTON.name(), 0) == ContentEnum. REMOTE .ordinal()) { view = ContentRemote.getRemoteView(inflater, container, savedInstanceState); Preferences.setPreferences(getActivity()); } ... } the if container == null, is always true. Why is this so? and the other problem is, when i press a button, the showDetails is called. When im in portrait mode, it works fine. But when im in landscape mode, the following error is shown when i press a button. Does anyone has an idea how can i solve this? thank you for your support <https://lh5.googleusercontent.com/_7FGGBnFM_RE/TcvqTciA4jI/AAAAAAAAAB4/VC7DswkWj6g/screen-capture-2.png> -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
