各位前輩大家好,小弟接觸android沒多久還是位新手, 目前在做作品時遇到了一個瓶頸,是在ListView.setAdapter() 短時間內大量重複更新時跳出以下錯誤: java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(2131296313, class android.widget.ListView) with Adapter(class com.example.avalon.PlayerAdapter)] 以下是小弟寫的Adapter的程式碼: public class PlayerAdapter extends BaseAdapter { private LayoutInflater playersInflater; public List<Player> playerslist; public PlayerAdapter(Context context, List<Player> playerslist) { // TODO 自動產生的建構子 Stub if(playerslist!=null){ playersInflater=LayoutInflater.from(context); this.playerslist=playerslist; PlayerAdapter.this.notifyDataSetChanged(); } } @Override public int getCount() { // TODO 自動產生的方法 Stub return (playerslist==null)? 0 : playerslist.size(); } @Oerride public Object getItem(int position) { // TODO 自動產生的方法 Stub return playerslist.get(position); } @Override public long getItemId(int position) { // TODO 自動產生的方法 Stub return playerslist.indexOf(getItem(position)); } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO 自動產生的方法 Stub if(playerslist.size()!=0){ try{ convertView=playersInflater.inflate (R.layout.players_list_item, null); ImageView iv_Players_Status=(ImageView) convertView.findViewById(R.id.IV_Players_Status); TextView tv_Players_Order=(TextView) convertView.findViewById(R.id.TV_Players_Order); TextView tv_Players_Anonymous=(TextView) convertView.findViewById(R.id.TV_Players_Anonymous); iv_Players_Status.setImageResource (playerslist.get(position).getStatus()); tv_Players_Order.setText(String.valueOf (playerslist.get(position).getOrder()).toString()); tv_Players_Anonymous.setText (playerslist.get(position).getAnonymity()); }catch(Exception e){ e.printStackTrace(); Log.e("text","PlayerAdapter="+e.toString()); } return convertView; }else{ convertView=playersInflater.inflate(R.layout.null_layout, null); return convertView; } } } 這幾天爬文有看到getCount()內寫成 return (playerslist==null)? 0 : playerslist.size(); 還有在更新資料時呼叫notifyDataSetChanged()通知系統更新Adapter 可是在大量更新時app還是會崩潰跳出此錯誤 有聽人說可以在更新時隱藏按鈕,到更新完後在顯示按鈕 但是小弟是寫socket連伺服器,所以可以多人更新所以以上方法可能無法解決 還希望各位可以協助解決,謝謝~ --
