How to replace a Fragment on button click of that fragment?

by

you can replace fragment by FragmentTransaction.

Here you go.

Make an interface.

public interface FragmentChangeListener 
{
    public void replaceFragment(Fragment fragment); 
}

implements your Fragment holding activity with this interface.

public class HomeScreen extends FragmentActivity implements
        FragmentChangeListener {


         @Override
         public void replaceFragment(Fragment fragment) {
            FragmentManager fragmentManager = getSupportFragmentManager();;     
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(mContainerId, fragment, fragment.toString());
            fragmentTransaction.addToBackStack(fragment.toString());
            fragmentTransaction.commit();   
    }

}

Call this method from Fragments like this.

//In your fragment.

public void showOtherFragment()
{
       Fragment fr=new NewDisplayingFragment();
             FragmentChangeListener fc=(FragmentChangeListener)getActivity();
             fc.replaceFragment(fr);
}

Hope this will work!

NOTE: mContainerId is id of the view who is holding the fragments inside.
You should override Fragment’s onString() method as well.
