json文字列オブジェクト（englishSentence）からautocompleteTextviewに値を表示します。

TranslatorModelクラスには、jsonObjectsのgetterメソッドとsetterメソッドがあります。

arrayAdapter宣言行でエラーが見つかりました。あなたが故にカスタムオブジェクトではない文字列を使用している

Answer 1

リストは、カスタムクラスのオブジェクトが含まれているので、あなたはこの

public class MyClassAdapter extends ArrayAdapter<MyClass> { 

    private static class ViewHolder { 
     private TextView itemView; 
    } 

    public MyClassAdapter(Context context, int textViewResourceId, ArrayList<MyClass> items) { 
     super(context, textViewResourceId, items); 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 

     if (convertView == null) { 
      convertView = LayoutInflater.from(this.getContext()) 
      .inflate(R.layout.listview_association, parent, false); 

      viewHolder = new ViewHolder(); 
      viewHolder.itemView = (TextView) convertView.findViewById(R.id.ItemView); 

      convertView.setTag(viewHolder); 
     } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
     } 

     MyClass item = getItem(position); 
     if (item!= null) { 
      // My layout has only one TextView 
       // do whatever you want with your string and long 
      viewHolder.itemView.setText(String.format("%s %d", item.reason, item.long_val)); 
     } 

     return convertView; 
    } 
}
