Android find resource by id during the runtime

Question

If I get the error "android.content.res.Resources$NotFoundException: Resource ID #0x7f050007 type #0x12 is not valid" can I find some what this resource is if I know its ID?

        ListView list = (ListView)findViewById(R.id.messages_list_view);
        list.setAdapter(new ArrayAdapter<String>(context,
        R.layout.messages_list, headers));

messages_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/messages_list_layout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <ListView android:id="@+id/messages_list_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

Answer 1

I Got this error when using ListView in a Fragment.

Resolved by moving the setAdapter lines to the onViewCreated function of the Fragment. (makes sense that before the view is created the ListView is invalid).

so you get :

public void onViewCreated(View view,Bundle savedInstanceState){
    ListView list = (ListView) getView().findViewById(R.id.thelist);
    list.setAdapter(mAdapter);
}

For those whom other mentioned solutions don't work.

I did this silly mistake:-

setContentView(R.id.something);

Instead of

setContentView(R.layout.something);

Corrected that, and error was gone :D
