    <p>I am trying to implement 3 fragments within View pager. All of the fragments has their own list view. Whenever i am swiping back to the first fragment the list view is updating itself getting duplicate values. here is the main activity implementing the view pager. Please suggest.</p> <pre><code>public class MainActivity extends FragmentActivity { /** Called when the activity is first created. */ static AppSectionsPagerAdapter mAppSectionsPagerAdapter; ViewPager mViewPager; SearchView mSearchView; MenuItem menuSearch; Boolean flag = false; String pid; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setupActionBar(); getActionBar().setTitle("All Patients"); mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(getSupportFragmentManager()); // Set up the ViewPager, attaching the adapter and setting up a listener for when the // user swipes between sections. mViewPager = (ViewPager) findViewById(R.id.pager); mViewPager.setAdapter(mAppSectionsPagerAdapter); mViewPager.setOnPageChangeListener(new OnPageChangeListener() { public void onPageSelected(int position) { //mAppSectionsPagerAdapter.getItemPosition(getFragmentManager().findFragmentById(position)); //getActionBar().setTitle(mAppSectionsPagerAdapter.getPageTitle(position)); if(position==0){ getActionBar().setTitle("All Patients"); //flag = true; //menuSearch.setVisible(true); invalidateOptionsMenu(); } if(position==1){ getActionBar().setTitle("All Doctors"); //flag=false; //menuSearch.setVisible(false); invalidateOptionsMenu(); } else getActionBar().setTitle("All Nurses"); invalidateOptionsMenu(); } public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } public void onPageScrollStateChanged(int state) { if (state == ViewPager.SCROLL_STATE_DRAGGING) { } if (state == ViewPager.SCROLL_STATE_IDLE) { } } }); } /** * A {@link FragmentPagerAdapter} that returns a fragment corresponding to one of the primary * sections of the app. */ public static class AppSectionsPagerAdapter extends FragmentPagerAdapter { public AppSectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int i) { switch (i) { case 0: // The first section of the app is the most interesting -- it offers // a launchpad into the other demonstrations in this example application. return new AllPatient(); case 1: //Intent intent = new Intent(MainActivity.this,abc.class); return new AllDoctors(); case 2: return new AllNurses(); } return null; } @Override public int getCount() { return 3; } } </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.
