fragmentpageradapter

My problem According to the Google's docs: You can now embed fragments inside fragments. This is useful for a variety of situations in which you want to place dynamic and re-usable UI components into a UI component that is itself dynamic and re-usable. For example, if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page. To nest a fragment, simply call getChildFragmentManager() on the Fragment in which you want to add a fragment. This returns a FragmentManager that you can use like you

I've got strange problem with FramentPageAdapter MainActivity.java @SuppressLint("ValidFragment") public class MainActivity<DashboardActivity> extends FragmentActivity implements ActionBar.TabListener { ... ... @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final ActionBar actionBar = getActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost); mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

I have a FragmentActivity in the first tab of a TabHost , and the FragmentActivity itself holds a ViewPager . The ViewPager 's setAdapter() method sets a FragmentPagerAdapter with a set of Fragment s. The goal is to have swipeable images in the first pane of the TabHost . To test it, I was loading a bunch of images that I had kept locally in the project's drawable directory. Everything worked beautifully. After having tested this initial setup, I'm downloading a bunch of image URLs' off a REST web service. I want these images to load lazily in the ViewPager , and I tried calling Picasso's load

Is it OK to keep an instance of every fragment that is created for a FragmentPagerAdapter inside the FragmentPagerAdapter ? Something like this: @Override public Object instantiateItem(ViewGroup container, int position) switch(position){ case 0: fragment0 = super.instantiateItem(container, position); return fragment0; case 1: fragment1 = super.instantiateItem(container, position); return fragment1; default: return super.instantiateItem(container, position); } } Will I run into memory issues? The idea is to do something like MyFragmentPagerAdapter.fragment0 in order to get a reference to the

I'm switching some Android Facebook code from an Activity to a Fragment . Prior to the switch everything worked fine, but now the onComplete() callback is not being executed. Does the Facebook code not work with Fragments , or am I doing something wrong? Here's the original code (in a SherlockActivity ): if (!mFacebook.isSessionValid()) { mFacebook.authorize(MyActivity.this, permissions, new DialogListener() { @Override public void onComplete(Bundle values) { ... } // CALLED AS EXPECTED } } And here's the new code (in a SherlockFragment): if (!mFacebook.isSessionValid()) { mFacebook.authorize

I'm an android beginner, trying to learn, and this is my first question, so please excuse me if the question is too simple and please tell me if I'm using the forum incorrectly. I have a FragmentActivity using a layout that includes a viewpager; the activity creates an instance of MyFragmentPagerAdapter, which creates several instances of MyFragment. All are support.v4 versions. I'm trying to find a way to pass an integer value (representing a selection the user has made previously, which could actually be a drawable id) to the fragment. I'm using an intent to pass it to this activity and I
