Tabs Activities inside Fragment Activity

Fragments are used for creating dynamic and multi-pane user interface in android. A fragment works as a modular section of an activity. A fragment inflates a layout to display contents. Android provides a Fragment Activity inside this we can inflate any number of independent fragment. So Fragment Activity is a base for fragment.

A tab activity can display fragment by visiting tabs. Each tab of tab activity inflate a different fragment.

But sometimes there is requirement to display tabs inside a fragment activity. I wrote the code for how to call many activities inside activity using fragment.

Main Fragment with Tabs
Fragment Activities Layout Code

Fragment Activities Source Code

public class HomeFragment extends Fragment {
	
	FragmentTransaction fragmentTransaction;
	FragmentManager fragmentManager;

	BuyAdsFragment buyAdsFragment;
	SellAdsFragment sellAdsFragment;
	LocationFragment locationFragment;

	Button btnbuyads,btnsellads,btnlocation;	
	View rootView;

	@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
		rootView = inflater.inflate(R.layout.fragment_home_fragment, container, false);
		
		fragmentManager = getFragmentManager();
		fragmentTransaction = fragmentManager.beginTransaction();
		
		//Default fragment 
		buyAdsFragment= new BuyAdsFragment();
		fragmentTransaction.replace(R.id.frag_layout, buyAdsFragment);  //replacing fragment with the previous contents of   framelayout (frag_layout)
		fragmentTransaction.commit();
		
		btnbuyads=(Button)rootView.findViewById(R.id.btnbuyads);
		btnbuyads.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				// inflate buyads fragment when tab1 is pressed
				buyAds();
			}
		});
		btnsellads=(Button)rootView.findViewById(R.id.btnsellads);
		btnsellads.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
			//inflate sellAds fragment when tab2 is pressed	
			sellAds();	
			}
		});
		btnlocation=(Button)rootView.findViewById(R.id.btnlocation);
		btnlocation.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				//inflate location fragment when tab3 is pressed
				location();
			}
		});
		
		return rootView;
		
    }
	//Methods to inflate layout when particular tab is pressed
	
	public void buyAds()
	{
		fragmentManager = getFragmentManager();
		fragmentTransaction = fragmentManager.beginTransaction();
		buyAdsFragment= new BuyAdsFragment();
		fragmentTransaction.replace(R.id.frag_layout, buyAdsFragment);
		fragmentTransaction.commit();
	}
	
	public void location()
	{
		fragmentManager = getFragmentManager();
		fragmentTransaction = fragmentManager.beginTransaction();
		locationFragment= new LocationFragment();
		fragmentTransaction.replace(R.id.frag_layout, locationFragment);
		fragmentTransaction.commit();
		
	}
	
	public void sellAds()
	{
		fragmentManager = getFragmentManager();
		fragmentTransaction = fragmentManager.beginTransaction();		
		sellAdsFragment= new SellAdsFragment();
		fragmentTransaction.replace(R.id.frag_layout, sellAdsFragment);		
		fragmentTransaction.commit();
	}

}

Note :- Import Fragment class from “android.app.Fragment” instead of V4.app.Fragment”

Location Fragment

 public class LocationFragment extends Fragment {

@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View rootView = inflater.inflate(R.layout.fragment_location,
				container, false);
		return rootView;
		}	

}

BuyAds Fragment

 public class BuyAdsFragment extends Fragment {

@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View rootView = inflater.inflate(R.layout.fragment_buyads,
				container, false);
		return rootView;
		}	

}

Thanks
