Answer 1

Add ItemClickListener below

l = (ListView) rootView.findViewById(R.id.myListView);

in function onCreateView();

l.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
        // Do something             
    }
});

Answer 2

You need to use OnItemClickListener and add/replace existing fragment in the container.

l.setOnItemClickListener(new OnItemClickListener()
{
    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
    { 
        Toast.makeText(getActivity(), "Clicked at" + position, Toast.LENGTH_SHORT).show();
    }
});

Also you need not have runOnUiThread in onPostExecute as it is invoked on the ui thread.

You also need to use interface as a call back to the Activity and then add/replace fragment to the container in Activity

Answer 3

Try this..

Add below ItemClickListener Codes before return rootView;

l.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
            // Do something             
        }
    });
