Update ListView in the main thread from another thread

Question

I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged().

Answer 1

The trick here is the position where you put the

mAdapter.notifyDataSetChanged();

Here a simple example :

mRecyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
mAdapter = new myAdapter(......);
mAdapter.notifyDataSetChanged();
mRecyclerView.setAdapter(mAdapter);

this work for me perfectly.
