How to include the activity in fragment tabs ?

I am developing an app in which there are two fragmenttabs.when pressing the tabs corresponding fragments will appear.that works fine.but what I want an activity inside the fragmenttabs. I am using ABS library for this. ``` ActionBar bar = getSupportActionBar(); bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); ActionBar.Tab tab1 = bar.newTab(); ActionBar.Tab tab2 = bar.newTab(); tab1.setText("Fragment A"); tab2.setText("Fragment B"); tab1.setTabListener(new MyTabListener<FragmentA>(this, "tab1", FragmentA.class, null)); tab2.setTabListener(new MyTabListener<FragmentB>(this, "tab1", FragmentB.class, null)); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // app icon in action bar clicked; go Location selection Intent intent = new Intent(FragmentDemoActivity.this, TestActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); return true; default: return super.onOptionsItemSelected(item); } } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putInt("tab", getSupportActionBar() .getSelectedNavigationIndex()); } ``` listnerclass is ``` public class MyTabListener<T extends Fragment> implements ActionBar.TabListener { private final FragmentActivity mActivity; private final String mTag; private final Class<T> mClass; private final Bundle mArgs; private Fragment mFragment; public MyTabListener(FragmentActivity activity, String tag, Class<T> clz, Bundle args) { mActivity = activity; mTag = tag; mClass = clz; mArgs = args; FragmentTransaction ft = mActivity.getSupportFragmentManager() .beginTransaction(); mFragment = mActivity.getSupportFragmentManager().findFragmentByTag( mTag); if (mFragment != null && !mFragment.isDetached()) { ft.detach(mFragment); } } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { ft = mActivity.getSupportFragmentManager().beginTransaction(); if (mFragment == null) { mFragment = Fragment .instantiate(mActivity, mClass.getName(), mArgs); ft.add(android.R.id.content, mFragment, mTag); ft.commit(); } else { ft.attach(mFragment); ft.commit(); } } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { ft = mActivity.getSupportFragmentManager().beginTransaction(); if (mFragment != null) { ft.detach(mFragment); ft.commitAllowingStateLoss(); } } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } ``` Fragmentclass ``` public class FragmentB extends Fragment { Button button; @Override public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle saved) { return inflater.inflate(R.layout.frag_b, group, false); } @Override public void onActivityCreated (Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); button = (Button) getActivity().findViewById(R.id.button2); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); builder.setTitle("Fragment B"); builder.setMessage("What would you like to do?"); builder.setPositiveButton("Nothing", null); builder.setNegativeButton("Leave me alone!", null); builder.show(); } }); } } ``` i wnt to include the following activity in the fragmentB ``` public class TestActivity extends Activity { Button b1, b2; TextView tv; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.testactivity); b1 = (Button) findViewById(R.id.button1); b2 = (Button) findViewById(R.id.button2); tv = (TextView) findViewById(R.id.textView1); b1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { tv.setText("You Clicked on Button 1"); } }); b2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { tv.setText("You Clicked on Button 2"); } }); } } ``` I have lot of created activites to include in the fragment..its un imaginable to recreate in onActivityCreated of fragment class. according to this I have to modify my main application.
