This is MyTabActivity.java class
public class MyTabActivity extends FragmentActivity {
ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_layout);
TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
Tab = (ViewPager)findViewById(R.id.pager);
Tab.setOnPageChangeListener(
new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar = getActionBar();
actionBar.setSelectedNavigationItem(position); }
});
Tab.setAdapter(TabAdapter);
actionBar = getActionBar();
//Enable Tabs on Action Bar
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.TabListener tabListener = new ActionBar.TabListener(){
@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
Toast.makeText(getBaseContext(), "Tab ReSelected: " + tab.getPosition(), Toast.LENGTH_SHORT).show();
}
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
Tab.setCurrentItem(tab.getPosition());
Toast.makeText(getBaseContext(), "Tab Selected: " + tab.getPosition(), Toast.LENGTH_SHORT).show();
}
@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
Toast.makeText(getBaseContext(), "Tab UnSelected: " + tab.getPosition(), Toast.LENGTH_SHORT).show();
}};
//Add New Tab
actionBar.addTab(actionBar.newTab().setText("Tab1").setTabListener(tabListener));
actionBar.addTab(actionBar.newTab().setText("Tab2").setTabListener(tabListener));
}
}
This is TabPagerAdapter.java
public class TabPagerAdapter extends FragmentStatePagerAdapter {
public TabPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int i) {
switch (i) {
case 0:
return new Tab1Activity();
case 1:
return new Tab2Activity();
}
return null;
}
@Override
public int getCount() {
//No of Tabs
return 2;
}
}
public class Tab1Activity extends Fragment {
@Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
/// code to display LIstView
.
.
//here i m trying to invoke other tab on click of list item...this where i stuck
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adptr, View view, int pos,
long id) {
/// this code here is not working for me
Tab2Activity myDetailFragment = new Tab2Activity ();
Bundle bundle = new Bundle();
bundle.putString("KEY_DETAIL", "Hi");
myDetailFragment.setArguments(bundle);
FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
fragmentTransaction.attach(myDetailFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}});
return monthlyView;
}
}
This is Tab2Activity.java
public class Tab2Activity extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View dailyView = inflater.inflate(R.layout.activity_mian, container, false);
// displaying list item based on the input from tab1
return dailyView;
}
}
This is activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- The main content view starts -->
<LinearLayout
