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?

The answer to your problem is easy: replace the current Fragment
with the new Fragment
and push transaction onto the backstack. This preserves back button behaviour...
Creating a new Activity
really defeats the whole purpose to use fragments anyway...very counter productive.
@Override
public void onClick(View v) {
// Create new fragment and transaction
Fragment newFragment = new chartsFragment();
// consider using Java coding conventions (upper first char class names!!!)
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
}

Try this it may help you:
private void changeFragment(Fragment targetFragment){
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.main_fragment, targetFragment, "fragment")
.setTransitionStyle(FragmentTransaction.TRANSIT_FRAGMENT_FADE)
.commit();
}
Try this it may help you:
public void ButtonClick(View view) {
Fragment mFragment = new YourNextFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, mFragment).commit();
}
