fragment side by side


Recommended Posts

what I'm trying to do is in portrait mode display a fragment, in landscape mode display two fragments side by side.


it all seems to work fine until I rotate the emulator from landscape to portrait then the app crashes with this:


java.lang.RuntimeException: Unable to start activity ComponentInfo{com.fragmentapp/com.fragmentapp.MainActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x7f030002


it all works fine if I put the fragments in the XML but I'm trying to call them programically with this:




protected void onCreate(Bundle savedInstanceState)


FragmentTransaction mft = getFragmentManager().beginTransaction();




FragmentOne mFragmentOne = new FragmentOne();

//getFragmentManager().beginTransaction().add(R.id.container, mFragmentOne).commit();

mft.add(R.id.leftfragment, mFragmentOne);

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)


FragmentTwo mFragmentTwo = new FragmentTwo();

mft.add(R.id.rightfragment, mFragmentTwo);

//getFragmentManager().beginTransaction().add(R.id.container, mFragmentTwo).commit();




FrameLayout FragmentContainer = (FrameLayout) findViewById(R.id.rightfragment);

if (FragmentContainer != null)


getFragmentManager().beginTransaction().remove(new FragmentTwo()).commit();








I do have fragmentone.xml in layout folder where I have fragmetone.xml/fragmenttwo.xml in layout-land folder if this helps??


any body got any ideas!
