How to pass a packet to a fragment

Question

First of all, let me say that everyone on the East Coast is fine after Hurricane Sandy. I was lucky in this, although I live in New York, I have not even lost power. My thoughts go to those of you who are not so lucky. Now, when I get back to work in three days, I need help with fragments. I am trying to pass a bundle to a fragment and it does not work. I know that I set up the generic fragment correctly, because if I don't try to pass the Bundle, it works fine. So here is my activity in which I pass the Bundle:

public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent choice = new Intent(getApplicationContext(), com.MyProject.project.MyList.class); Bundle dataBundle = new Bundle(); String chosenValue = values[position]; dataBundle.putString("Level",chosenValue); choice.putExtras(dataBundle); startActivity(choice); } 

Now here is my activity without the Sachet. This works great:

 public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); String[] values = new String[] { "Enterprise", "Star Trek", "Next Generation", "Deep Space 9", "Voyager"}; ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, values); setListAdapter(adapter); } 

However, when I try to get information from the Bundle, this will not work. Here is my code:

 public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); Bundle info = getArguments(); String level = info.getString("level"); String[] values = new String[] {level, level}; ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, values); setListAdapter(adapter); } 

When I run this and click on my choice in my work, the application just freezes. LogCat doesn't seem to give me much information about this. Anyone see any problems here?

Thanks!

You need to set the arguments in the fragment.

In onCreate action:

 Fragmet myFragment = new MyFragment(); myFragment.setArguments( getIntent().getExtras() );
