Android Refresh Listview after Delete
<p>I'm trying to refresh my listview after the item delete. But it doesnt seems to work. Am i missing something. I used listAdapter.notifyDataSetChanged(); not working either. Could somebody please assist me? Thank you</p>

<pre><code>@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        getActivity().setContentView(R.layout.dl_listview);

        View empty = getActivity().findViewById(R.id.empty);
        DLListView = (ListView) getActivity().findViewById(R.id.DLListView);
        DLListView.setEmptyView(empty);

        if (!Environment.getExternalStorageState().equals(
                Environment.MEDIA_MOUNTED)) {
            Toast.makeText(getActivity(),
                    "Error! No SDCARD Found!",
                    Toast.LENGTH_LONG).show();
        } else {
            File directory = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "St");
            directory.mkdirs();
        }
        DLListView = (ListView) getActivity().findViewById(R.id.DLListView);

        myList = new ArrayList&lt;String&gt;();

        File sdCard = Environment.getExternalStorageDirectory();
        file = new File(sdCard.getAbsolutePath() + "/St/");

        File list[] = file.listFiles();

        for (int i = 0; i &lt; list.length; i++) {
            String fileName = list[i].getName();
            fileName = fileName.replace(".txt", "");
            myList.add(fileName);

        }

        listAdapter = new ArrayAdapter&lt;String&gt;(getActivity(),
