問題解決：The content of the adapter has changed but ListView did not receive a notification

1. 不要在後臺線程中直接調用adapter

2. 不要在後臺線程中修改adapter綁定的數據

若是對adapter或者adapter綁定的數據是在線程中，加上runOnUiThread就能夠了

runOnUiThread(new Runnable(){

        public void run(){

                //修改數據

              datalist.add(......);

              //notify

               adapter.notifyDataSetChanged();

    }

}
