The error is here:
ListAdapter adapter = new ArrayAdapter<String>(
this,
R.layout.conversation_item,
chatList
);
getListView().setAdapter(adapter);
No error when I remove it.
ListAdapter adapter = new ArrayAdapter<String>(
this,
R.layout.conversation_item,
chatList
);
getListView().setAdapter(adapter);
What is the solution please?

I’m pretty sure the problem lies in your
conversation_itemlayout. The docs state that you must provide a resource with a single TextView. What does that layout look like?As an example, this is what the simple_list_item_1 layout looks like, yours should be pretty similar.
EDIT:
I just edited the question so your layout will show. Your layout is indeed wrong, you cannot have the linear layout there if you’re using that constructor. You can use the other constructor (
ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)) and provide your custom layout and your TextView’s id.
