android - Android - empty items added to the listview?

Question

I am trying to add running tasks to the ListView.

When i am adding first time using function called loadTasks(). it's added perfectly. But when i am trying to reload it, as i am refreshing the task list after every 10 seconds, its adding two or more empty items in my list.

リストをリロードするには、このコードを試してください

private Handler meethandler=new Handler()
    {
        public void handleMessage(Message msg) {
            ArrayAdapter aa=new ArrayAdapter<String>(HomeScreen.this,android.R.layout.test_list_item, mMeeting);
            mMeetinglist.setAdapter(aa);
            aa.notifyDataSetChanged();
            mMeetinglist.invalidate();              
        }

    };

リストを更新したいときは、このようにハンドラーを呼び出します

meethandler.sendemptymessage(0);
