Get view of Fragment from FragmentActivity

Question

I have a FragmentActivity where I add a Fragment. Depending on some situation, I want to access Buttons from that fragment's layout and change click listeners of them.

What I do is:

View view = myFragment.getView(); Button myButton = (Button) view.findViewById(R.id.my_button); myButton.setOnClickListener(new MyClickListener()); 

But the view variable is always null.

How can I get the view of the activity?

If you want to access your component and set some data, I suggest you to make a method inside the fragment like this:

import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button;  public class DetailFragment extends Fragment {      @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,             Bundle savedInstanceState) {         View view = inflater.inflate(R.layout.details, container, false);         return view;     }       public void setSettings(){         Button button = (Button) getView().findViewById(R.id.my_button);         button.setOnClickListener(new MyClickListener());     } }
