Android Listview text colour white onCreateView(instead of black)

问题

Attached are 2 photos one when the list is populated using the onCreateView when the app starts(white text) and the other is whenever the SetList() method is called

        public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
        ListView lv = (ListView) rootView.findViewById(R.id.listView1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(((MainActivity)getActivity()).getApplicationContext(), android.R.layout.simple_list_item_1,((MainActivity)getActivity()).Logs);
        lv.setAdapter(adapter);
        return rootView;
    }

    public void SetList()
{
    ListView lv = (ListView) findViewById(R.id.listView1);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,Logs);
    lv.setAdapter(adapter);
}

Problem solved by changing ArrayAdapter<String> adapter = new ArrayAdapter<String>(((MainActivity)getActivity()).getApplicationContext(), android.R.layout.simple_list_item_1,((MainActivity)getActivity()).Logs);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(((MainActivity)getActivity()).getBaseContext(), android.R.layout.simple_list_item_1,((MainActivity)getActivity()).Logs);

it seems like for some reason ((MainActivity)getActivity()).getApplicationContext() returns a different default text color than ((MainActivity)getActivity()).getBaseContext()

Change

ArrayAdapter<String> adapter = new ArrayAdapter<String>(((MainActivity)getActivity()).getApplicationContext(), android.R.layout.simple_selectable_list_item,((MainActivity)getActivity()).Logs);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(((MainActivity)getActivity()).getApplicationContext(), android.R.layout.simple_list_item_1,((MainActivity)getActivity()).Logs);

in onCreateView. The problem is that you are using 2 different layouts in the adapter. Using android.R.layout.simple_list_item_1 should give you TextView with black text the first time too.

try this, Override getView method and set text color like this

 countryadapter = new ArrayAdapter<String>(CreateGroupsActivity.this,
            android.R.layout.simple_spinner_item,
            CommonListClass.countryName) {
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            View v = super.getView(position, convertView, parent);
            ((TextView) v).setTextColor(getResources().getColor(R.color.black_color));
            return v;
        }

        @Override
        public View getDropDownView(int position, View convertView,
                ViewGroup parent) {
            // TODO Auto-generated method stub
            View v = super.getDropDownView(position, convertView, parent);
            ((TextView) v).setTextColor(getResources().getColor(R.color.black_color));
            return v;
        }
    };
