Notify ListView on receiving Dataset
I have a ListView that gets its dataset from a BaseAdapter. The ListView receives data when a menuItem is clicked. I am not able to notify my listView or my ListAdapter (inboxAdapter.notifyDataSetChanged()), doesnt work. Any other approaches.
case R.id.Get:
retrieveList();
inboxEmails = EmailElement.parseContent();
inboxAdapter = new nboxAdapter(getApplicationContext(),inboxEmails);
if(inboxAdapter !=null){
listView.setAdapter(inboxAdapter);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
inboxAdapter.no开发者_开发技巧tifyDataSetChanged();
}
break;
//this method retrieveList by sending sms
private void retrieveList(){
registerReceiver(new SMSSentReciever(), new IntentFilter(SMSInfo.SENT));
registerReceiver(new SMSDeliveredReciever(), new IntentFilter(SMSInfo.DELIVERED));
PendingIntent sentIntent = PendingIntent.getBroadcast(this, 0, new Intent(SMSInfo.SENT), 0);
PendingIntent deliveryIntent = PendingIntent.getBroadcast(this, 0, new Intent(SMSInfo.DELIVERED),0);
SmsManager.getDefault().sendTextMessage("5556",null, "fruits", sentIntent, deliveryIntent);
}
Based on the message from broadcast i need to update or notify my Listview, for now when i click the menu firstly i get my message on the emulator and then from the other emulator i send above message, the toast is shown,but not the listview but once i click the menu again i finally get the listview. WHat have i done wrong?
Instead of calling notifyDataSetChanged()
, calling listView1.setAdapter(adapter)
will force the listview to refresh.
