    <p>i have an activity with actionbarsherlock TabsNavigation (3 tabs) and when I press a tab i change the viewpager adapter of the corresponding fragment. it is working fine, the thing is that when I click on another tab besides the first created, the first page is always the one of that first tab. I tried to put invalidate() before changing the adapter, but it isnt working. anyone has any idea? here is the code:</p> <pre><code>public class Tabsteste2 extends SherlockFragmentActivity implements TabListener { static AdapterOpiniao mOdapter; static AdapterDados mDdapter; static AdapterFoto mFdapter; Bundle extras; JSONParser jsonParser = new JSONParser(); SharedPreferences mPrefs; static ViewPager mPager; static int countopiniao; static int countdados; static int countfoto; JSONArray perguntas = null; PageIndicator mIndicator; static ArrayList&lt;HashMap&lt;String, String&gt;&gt; opiniaolist; static ArrayList&lt;HashMap&lt;String, String&gt;&gt; dadoslist; static ArrayList&lt;HashMap&lt;String, String&gt;&gt; fotolist; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tabsteste2); opiniaolist = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); dadoslist = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); fotolist = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); mPager = (ViewPager)findViewById(R.id.pager); extras = getIntent().getExtras(); Boolean opiniaoflag = extras.getBoolean("opiniaoflag"); Boolean dadosflag = extras.getBoolean("dadosflag"); Boolean fotoflag = extras.getBoolean("fotoflag"); countdados= extras.getInt("countdados"); countopiniao=extras.getInt("countopiniao"); countfoto=extras.getInt("countfoto"); mPrefs = getSharedPreferences("mPrefs1",MODE_PRIVATE); Log.d("countdados",""+countdados); Log.d("countfoto",""+countfoto); Log.d("countopiniao",""+countopiniao); getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); if(opiniaoflag==true){ ActionBar.Tab opiniaotab = getSupportActionBar().newTab(); opiniaotab.setText("Opinião"); opiniaotab.setTag("op"); opiniaotab.setTabListener(this); mOdapter = new AdapterOpiniao(getSupportFragmentManager()); Log.d("Opiniao",""+opiniaotab.getTag()); getSupportActionBar().addTab(opiniaotab); }if(dadosflag == true){ ActionBar.Tab dadostab = getSupportActionBar().newTab(); dadostab.setText("Dados"); dadostab.setTag("dd"); mDdapter = new AdapterDados(getSupportFragmentManager()); dadostab.setTabListener(this); Log.d("Dados",""+dadostab.getTag()); getSupportActionBar().addTab(dadostab); } // mDdapter = new AdapterDados(getSupportFragmentManager()); if(fotoflag==true){ ActionBar.Tab fotostab = getSupportActionBar().newTab(); fotostab.setText("Fotos"); fotostab.setTag("ft"); mFdapter = new AdapterFoto(getSupportFragmentManager()); fotostab.setTabListener(this); Log.d("Foto",""+fotostab.getTag()); getSupportActionBar().addTab(fotostab); } new getpergunta().execute(); } @Override public void onTabReselected(Tab tab, FragmentTransaction transaction) { } @Override public void onTabSelected(Tab tab, FragmentTransaction transaction) { if(tab.getTag().equals("op")){ mPager.invalidate(); mPager.setAdapter(mOdapter); mIndicator = (UnderlinePageIndicator)findViewById(R.id.indicator); mIndicator.setViewPager(mPager); }else if (tab.getTag().equals("dd")){ mPager.invalidate(); mPager.setAdapter(mDdapter); mIndicator = (UnderlinePageIndicator)findViewById(R.id.indicator); mIndicator.setViewPager(mPager); }else if(tab.getTag().equals("ft")){ mPager.invalidate(); mPager.setAdapter(mFdapter); mIndicator = (UnderlinePageIndicator)findViewById(R.id.indicator); mIndicator.setViewPager(mPager); } } @Override public void onTabUnselected(Tab tab, FragmentTransaction transaction) { } public static class AdapterOpiniao extends FragmentPagerAdapter { public AdapterOpiniao(FragmentManager fm) { super(fm); } @Override public int getCount() { return countopiniao; } @Override public Fragment getItem(int position) { return FragmentOpinioes.newInstance(position); } } public static class AdapterDados extends FragmentPagerAdapter { public AdapterDados(FragmentManager fm) { super(fm); } @Override public int getCount() { return countdados; } @Override public Fragment getItem(int position) { return FragmentDados.newInstance(position); } } public static class AdapterFoto extends FragmentPagerAdapter { public AdapterFoto(FragmentManager fm) { super(fm); } @Override public int getCount() { return countfoto; } @Override public Fragment getItem(int position) { return FragmentFotos.newInstance(position); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
