Im working with fragments and..
Ive got a problem in my code that I just cant find.
The logcat points at this piece of code, in one of my fragments:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_main, container, false);
}
My main class (the FragmentActivity):
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.View;
public class Fragments extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragments);
MainActivity fragment = new MainActivity();
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
transaction.add(R.id.fragment_place, fragment);
transaction.commit();
}
public void onSelectFragment(View view) {
Fragment newFragment;
if (view == findViewById(R.id.add)) {
newFragment = new Add();
} else if (view == findViewById(R.id.map)) {
newFragment = new MainActivity();
} else {
newFragment = new MainActivity();
}
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
transaction.replace(R.id.fragment_place, newFragment);
transaction.addToBackStack(null);
transaction.commit();
}
}
and the logcat:

The class "MainActivity" is very long so I pasted it using pasebin:
Thanks for your assistance!
Edit:
private GoogleMap map;
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.map, map).commit();
it shows an error:
The method add(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, GoogleMap)
Caused by: java.lang.ClassCastException: com.google.android.gms.maps.MapFragment cannot be cast to android.support.v4.app.Fragment
You can't create a fragment inside a fragment using xml. You haven't posted the xml for the fragment, but I'm guessing you have a map fragment in there. You can still add it, but you need to add it dynamically using getChildFragmentManager()
