Add Fragment inside another Fragment

Normally we can add the multiple Fragment inside the FragmentActivity, But to add Fragment from inside the another Fragment is use the following way to achieve the task.

here i have added the Fragment in the Tab2Fragment Fragment class,with out changing the Tab also   using the following code

1.Tab2Fragment.java

public class Tab2Fragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.tab2_view, null);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        initView();
    }

    private void initView() {
        Button button = (Button) getView().findViewById(R.id.tab2_btn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                replaceFragment();
            }
        });
    }

    private void replaceFragment() {
        ((BaseContainerFragment)getParentFragment()).replaceFragment(new Tab2InnerFragment(), true);
    }
}

2.Tab2InnerFragment.java

public class Tab1InnerFragment extends Fragment {
    private boolean mIsViewInited;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.inner_tab1_view, null);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        initView();
    }

    private void initView() {
        Button button = (Button) getView().findViewById(R.id.back);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                goBack();
            }
        });
    }

    private void goBack() {
        ((BaseContainerFragment)getParentFragment()).popFragment();
    }
}

3.BaseContainerFragment.java

public class BaseContainerFragment extends Fragment {

    public void replaceFragment(Fragment fragment, boolean addToBackStack) {
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        if (addToBackStack) {
            transaction.addToBackStack(null);
        }
        transaction.replace(R.id.container_framelayout, fragment);
        transaction.commit();
        getChildFragmentManager().executePendingTransactions();
    }

    public boolean popFragment() {
        boolean isPop = false;
        if (getChildFragmentManager().getBackStackEntryCount() > 0) {
            isPop = true;
            getChildFragmentManager().popBackStack();
        }
        return isPop;
    }
}
