不將項目添加到ArrayAdapter

Question

所以我有這樣的代碼：

suggestionsAdapter.clear(); 
       locations.clear(); 
       List<Predictions> predictions = gson.fromJson(jsonObject.getJSONArray("predictions").toString(), new TypeToken<List<Predictions>>(){}.getType()); 
       for(Predictions prediction : predictions){ 
        String title = prediction.terms.get(0).value; 
        locations.add(title); 
        suggestionsAdapter.add(title); 
       } 
       Log.i("","loc are:" + locations); 
       Log.i("","locations are:" + locations.size()); 
       suggestionsAdapter.notifyDataSetChanged(); 
       Log.i("","suggestion adapter size:" + suggestionsAdapter.getCount()); 

而且我回來的：

03-30 10:55:56.474: I/(3185): loc are:[Albert Cuypstraat, Albert Cuyp Market, Albania, Alblasserdam, Albert Cuypstraat] 
03-30 10:55:56.474: I/(3185): locations are:5 
03-30 10:55:56.474: I/(3185): suggestion adapter size:0 

這究竟是爲什麼？ PS：這發生在一個偵聽器內部，該偵聽器從Google地方查詢中獲取預測結果。 更改爲：

suggestionsAdapter.addAll(locations); 
         suggestionsAdapter.notifyDataSetChanged(); 

還是同樣的結果，有時我得到：

03-30 11:03:25.876: I/(10409): loc are:[Albert Cuypstraat, Albert Cuyp Market, Albert Cuypstraat, AH Haarlemmerdijk, Albert Heijn] 
03-30 11:03:25.876: I/(10409): locations are:5 
03-30 11:03:25.876: I/(10409): suggestion adapter size:3

我用的是列表的AutoCompleteTextView。這就是問題所在。當加載列表時，AutoCompleteTextView被過濾，因此爲什麼它不顯示響應。 我使用自定義的autoCompleteTextView解決了這個問題，我從這裏取了： https://www.codeofaninja.com/2013/12/android-autocompletetextview-custom-arrayadapter-sqlite.html
