Start a fragment via Intent within a Fragment

Issue

I want to launch a new fragment to view some data. Currently, I have a main activity that has a bunch of actionbar tabs, each of which is a fragment. So, within a tab fragment, I have a button, chartsButton. I have my onclicklistener all set for it, and here's the onClick method:

public OnClickListener chartsListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
        Intent chartFragment = new Intent();
        startActivity(chartFragment);   
    }
};

Now, as I said, this listener is within a class that extends Fragment. So, I want to launch a new fragment (chartsFragment) via the intent to replace the whole screen. When the user clicks back, it'll bring them back to the tabs and main activity. Here's my chart fragment:

public class chartsFragment extends Fragment {

    public View onCreateView() {
        //LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState
        LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        return (inflater.inflate(R.layout.chartfragment, null));
    }
}

The current error I am dealing with: "android.content.ActivityNotFoundException: No Activity found to handle Intent { }". That's fine, I understand that I could use getActivity().startActivity(chartsFragment), but that results in the same error. I suppose what I am looking for here, is how do I launch an intent from within a fragment that results in opening a new fragment?

Solution

You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.

So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filters.
