After Android onResume ListView is empty

I have a ListView which onResume I am trying to populate with data from a SQL Lite Database. During resume I add a click listener and repopulate the List View. The onResume, populateListView(), and onPause methods are below. The full source code is available on GitHub.

onResume:

@Override
protected void onResume() {
    IntentFilter filter = new IntentFilter();
    filter.addAction(TalkServerIntent.INTENT_NEW_MESSAGES.toString());
    registerReceiver(receiver, filter);

    setContentView(R.layout.main);

    talkListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parentView, View childView,
                            int position, long id) {
            GeoCamTalkMessage msg = adapter.getTalkMessage(position);
            if (msg.hasAudio()) {
                try {
                    UIUtils.playAudio(getApplicationContext(), msg, player,
                            siteAuth);
                } catch (Exception e) {
                    UIUtils.displayException(getApplicationContext(), e,
                            "Cannot retrieve audio");
                }
            }
        }
    });

    populateListView();
    super.onResume();
}

populateListView:

private void populateListView() {
    try {
        talkMessages = messageStore.getAllMessages();
    } catch (Exception e) {
        Log.i("Talk", "Error:" + e.getMessage());
    }

    if (talkMessages != null) {
        adapter.setTalkMessages(talkMessages);
        talkListView.setAdapter(adapter);
    }
}

I'm not doing anything special on the onPause, but since the values are stored in the database didn't think 开发者_如何学运维I would have to.

onPause

@Override
protected void onPause() {
    unregisterReceiver(receiver);
    super.onPause();
}

What am I doing wrong that is causing the ListView to not be refreshed onResume?

You could try moving setContentView(R.layout.main); to your onCreate() method.

Setting it in onResume() every time might cause issues.
