  1. POTabhost inside a SherlockFragment using ViewPageIndicator
    text
    copied!<p>So I have 3 Sherlock Fragments setup and working fine with ViewPageIndicator. What I'd like to do now is put a TabHost inside one of the Fragments so that it displays 2 separate tabs (at the bottom). I believe this means I need to have 2 more Fragments to put inside the 3rd Fragment controlled by the TabHost.</p> <p>Considering the TabHost needs to be created inside a Fragment, I'm not sure how to properly create it.</p> <p>Here is the code for the Fragment I've gotten working from <a href="http://droidista.blogspot.com/2012/08/making-actionbarsherlock-and.html" rel="nofollow">this tutorial</a>, which I've tried to update to add the TabHost unsuccessfully:</p> <p>TestFragment3.java</p> <pre><code>public class TestFragment3 extends SherlockFragment { private String mContent = "none"; public static TestFragment3 newInstance(String text) { TestFragment3 fragment = new TestFragment3(); // Supply num input as an argument. Bundle args = new Bundle(); args.putString(KEY_TAB_NUM, text); fragment.setArguments(args); return fragment; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.activity_main, null); String text = getString(R.string.tab_page_num) + mContent; ((TextView)view.findViewById(R.id.text)).setText(text); return view; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mContent = getArguments() != null ? getArguments().getString(KEY_TAB_NUM) : "none"; } } </code></pre> <p>MainActivity.java</p> <pre><code>public class MainActivity extends SherlockFragmentActivity { private static final String[] TAB_TITLES = new String[] { "This", "Is", "A", "ViewPager" }; TestFragmentAdapter mAdapter; ViewPager mPager; PageIndicator mIndicator; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.simple_tabs); mAdapter = new TestFragmentAdapter(getSupportFragmentManager()); mPager = (ViewPager)findViewById(R.id.pager); mPager.setAdapter(mAdapter); mIndicator = (TabPageIndicator)findViewById(R.id.indicator); mIndicator.setViewPager(mPager); } class TestFragmentAdapter extends FragmentPagerAdapter { private int mCount = TAB_TITLES.length; public TestFragmentAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return TestFragment.newInstance(String.valueOf(position)); } @Override public int getCount() { return mCount; } @Override public CharSequence getPageTitle(int position) { return TAB_TITLES[position]; } } } </code></pre> <p>Do I need to create a new SherlockFragmentActivity and add the 2 additional SherlockFragments to that TabHost? If so, how do I setup the MainActivity with 3 Fragments to use another Activity, not a Fragment, for its 3rd Fragment?</p> <p>I'm getting this error for trying to put a Fragment within a Fragment...</p> <pre><code>11-14 19:10:54.271: E/AndroidRuntime(2812): java.lang.IllegalStateException: Recursive entry to executePendingTransactions 11-14 19:10:54.271: E/AndroidRuntime(2812): at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1388) 11-14 19:10:54.271: E/AndroidRuntime(2812): at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:431) 11-14 19:10:54.271: E/AndroidRuntime(2812): at com.example.demolistview.EventInviteesFragment$TabManager.onTabChanged(EventInviteesFragment.java:152) 11-14 19:10:54.271: E/AndroidRuntime(2812): at android.widget.TabHost.invokeOnTabChangeListener(TabHost.java:391) 11-14 19:10:54.271: E/AndroidRuntime(2812): at android.widget.TabHost.setCurrentTab(TabHost.java:376) 11-14 19:10:54.271: E/AndroidRuntime(2812): at android.widget.TabHost.addTab(TabHost.java:236) ... ... ... </code></pre>
