Android onResume ListView为空之后
|
我有一个ListView，我试图用SQL Lite数据库中的数据填充onResume。在简历期间，我添加了一个单击侦听器，然后重新填充了列表视图。下面是onResume，populateListView（）和onPause方法。完整的源代码可在GitHub上找到。
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();
}
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);
}
}
@Override
protected void onPause() {
unregisterReceiver(receiver);
super.onPause();
}
