    <p>I have implemented a swipey tabs app using viewpager by using this template in Eclipse <img src="https://i.stack.imgur.com/Asl1p.png" alt="enter image description here"></p> <p>Now i get an activity which extends FragmentActivity like this</p> <pre><code> package com.example.abcd2; import java.util.Locale; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.app.NavUtils; import android.support.v4.view.ViewPager; import android.view.Gravity; import android.view.LayoutInflater; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class MainActivity extends FragmentActivity { /** * The {@link android.support.v4.view.PagerAdapter} that will provide * fragments for each of the sections. We use a * {@link android.support.v4.app.FragmentPagerAdapter} derivative, which * will keep every loaded fragment in memory. If this becomes too memory * intensive, it may be best to switch to a * {@link android.support.v4.app.FragmentStatePagerAdapter}. */ SectionsPagerAdapter mSectionsPagerAdapter; /** * The {@link ViewPager} that will host the section contents. */ ViewPager mViewPager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Create the adapter that will return a fragment for each of the three // primary sections of the app. mSectionsPagerAdapter = new SectionsPagerAdapter( getSupportFragmentManager()); // Set up the ViewPager with the sections adapter. mViewPager = (ViewPager) findViewById(R.id.pager); mViewPager.setAdapter(mSectionsPagerAdapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } /** * A {@link FragmentPagerAdapter} that returns a fragment corresponding to * one of the sections/tabs/pages. */ public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { // getItem is called to instantiate the fragment for the given page. // Return a DummySectionFragment (defined as a static inner class // below) with the page number as its lone argument. if(position==0) { Fragment frag2=new ShowFrag2(); return frag2;} else { Fragment fragment = new DummySectionFragment(); Bundle args = new Bundle(); args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1); fragment.setArguments(args); return fragment;} } @Override public int getCount() { // Show 3 total pages. return 3; } @Override public CharSequence getPageTitle(int position) { Locale l = Locale.getDefault(); switch (position) { case 0: return getString(R.string.title_section1).toUpperCase(l); case 1: return getString(R.string.title_section2).toUpperCase(l); case 2: return getString(R.string.title_section3).toUpperCase(l); } return null; } } /** * A dummy fragment representing a section of the app, but that simply * displays dummy text. */ public static class DummySectionFragment extends Fragment { /** * The fragment argument representing the section number for this * fragment. */ public static final String ARG_SECTION_NUMBER = "section_number"; public DummySectionFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main_dummy, container, false); TextView dummyTextView = (TextView) rootView .findViewById(R.id.section_label); dummyTextView.setText(Integer.toString(getArguments().getInt( ARG_SECTION_NUMBER))); return rootView; } } } </code></pre> <p>In this, to create a new fragment in one of the tabs, i use if-else based on position in the getItem() method as shown. The fragment showfrag2 is this</p> <pre><code>import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class ShowFrag2 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.frag2, container, false); } } </code></pre> <p>My question is, how do i create a listview in one of this fragments . I would like to use a simple listview only in this manner </p> <pre><code>LevelAdapter adapter = new LevelAdapter(this, R.layout.list_item, weather_data); listView1 = (ListView)findViewById(R.id.listView1); listView1.setAdapter(adapter); </code></pre> <p>But this has been done in an activity. How can i use something like this in the fragment above. Also, i cannot use ListFragment as the getView() method is returning a fragment. Please help regarding how to implement this. Thanks EDIT: Here is my adapter code :</p> <pre><code> package com.example.abcd3; import android.app.Activity; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.TextView; public class LevelAdapter extends ArrayAdapter&lt;Level&gt; { static Context context; static int layoutResourceId; static Level data[] = null; /* public LevelAdapter(Context context, int layoutResourceId, Level[] data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; }*/ public LevelAdapter(ShowFrag1 showFrag1, int listItem, Level[] weather_data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; // TODO Auto-generated constructor stub } public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; WeatherHolder holder = null; if(row == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); row = inflater.inflate(layoutResourceId, parent, false); holder = new WeatherHolder(); holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon); holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle); // holder.imgIcon2=(ImageView)row.findViewById(R.id.imgIcon2); row.setTag(holder); } else { holder = (WeatherHolder)row.getTag(); } Level weather = data[position]; holder.txtTitle.setText(weather.title); holder.imgIcon.setImageResource(weather.icon); return row; } static class WeatherHolder { ImageView imgIcon; TextView txtTitle; // ImageView imgIcon2; } } </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.
