问题 I'm trying make an app that I'm building take a search term from the main activity, return results, and then have the results be clickable such that a detail could be viewed from each results. I'm doing this by using a MainActivity, a ResultsActivity, and PlaceActivity and then a ListFragmentClickable (which extends ListFragment). If the handset is oriented in portrait mode, the results list should be viewable, with the details being viewed only if a result is clicked. If the handset is

问题 I'm having trouble following a guide on using SQLite in Android. I'm using a ListFragment instead of a ListActivity (as in the example), so I have the ListFragment implement LoaderManager.LoaderCallbacks<Cursor> instead.

问题 Intro: The basic \"Fragments Tutorial\" pattern goes something like this: On a tablet, have a list on the left, details on the right. Both are Fragments and both reside in the same Activity . On a phone, have a list Fragment in one Activity . Launch a new Activity with the details Fragment . (e.g. Android 3.0 Fragments API by Dianne Hackborn and the Fragments API Guide) On both devices, functionality is in the Fragments . (simple) On the Tablet , the whole app is 1 Activity , on the phone ,

My class inherits Fragment and that's why it can't use getSupportFragmentManager(). I am using getChildFragmentManager and it is showing me Error - IllegalArguementException: No view found for id... error. Any guidance would be appreciated. Code for calling AttachmentsListFragment is Bundle b = new Bundle(); b.putSerializable("AttachmentsList", msg.attachments); AttachmentListFragment listfrag = new AttachmentListFragment(msg.attachments); FragmentTransaction transaction = getFragmentManager().beginTransaction(); transaction.add(R.id.attachmentslistcontainer, listfrag); transaction

问题 I\'m using the v4 compatibility ViewPager in Android. My FragmentActivity has a bunch of data which is to be displayed in different ways on different pages in my ViewPager. So far I just have 3 instances of the same ListFragment, but in the future I will have 3 instances of different ListFragments. The ViewPager is on a vertical phone screen, the lists are not side-by-side. Now a button on the ListFragment starts an separate full-page activity (via the FragmentActivity), which returns and
