Android Fragment no view found for ID?

Question

I have a fragment I am trying to add into a view.

FragmentManager fragMgr=getSupportFragmentManager(); feed_parser_activity content = (feed_parser_activity)fragMgr                                     .findFragmentById(R.id.feedContentContainer); FragmentTransaction xaction=fragMgr.beginTransaction();  if (content == null || content.isRemoving()) {     content=new feed_parser_activity(item.getLink().toString());     xaction         .add(R.id.feedContentContainer, content)         .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)         .addToBackStack(null)         .commit();     Log.e("Abstract", "DONE"); } 

When this code is executed I get the following error in debug..

java.lang.IllegalArgumentException: No view found for id 0x7f080011     for fragment feed_parser_activity{41882f50 #2 id=0x7f080011} 

feed_parser_activity is a Fragment that is set to Fragment layout in xml.
I am using a FragmentActivity to host the Fragment Layout holding the feed_parser_layout.
Am I coding this correctly above?

Answer 1

I was having this problem too, until I realized that I had specified the wrong layout in setContentView() of the onCreate() method of the FragmentActivity.

The id passed into FragmentTransaction.add(), in your case R.id.feedContentContainer, must be a child of the layout specified in setContentView().

You didn't show us your onCreate() method, so perhaps this is the same problem.

This error also occurs when having nested Fragments and adding them with getSupportFragmentManager() instead of getChildFragmentManager().
