このファイルからデータを抽出するのが難しいです。リクエストを送信するためにVolleyを使用し、Androidアプリケーション用にこれらの素材を抽出するためにJSONを使用しています。私は最初のJSON配列、すなわち名前、id、place_id、電話などを取得することができます。しかし、私は各人、weekday_text、写真などのレビューとしてJSON配列内のデータを取得することができませんので、助けてください私は必要な情報を得る方法を教えてください。事前に感謝します。あなたはJSONrequestを使用している可能性がありGoogle Place Apiから配列データを抽出する方法

はどのようにあなたが最初にJSON配列を取得するのですか? 'JsonParser'を使いましたか? – mismanc

答えて

JsonParserを使用して逆シリアル化できます。私は下のサンプルを書きます。しかし、私はあなたにこの方法を使用することをお勧めしますhttps://stackoverflow.com/a/2865580/1562723 Gsonによってjsonにdeseriliazeする。

JsonElement jelement = new JsonParser().parse(jsonLine); 
JsonObject jobject = jelement.getAsJsonObject(); 
jobject = jobject.getAsJsonObject("result"); 

/*Review*/ 
JsonArray jarray = jobject.getAsJsonArray("reviews"); 
/*For inside*/ 
JsonObject jreview = jarray.get(0).getAsJsonObject(); 
String authorName = jreview.get("author_name").toString(); 

/*Opening hours*/ 
JsonObject opObject = jobject.getAsJsonObject("opening_hours"); 
JsonArray jWeekDayArray = jobject.getAsJsonArray("weekday_text"); 
String weekdayText = jWeekDayArray.get(0).toString(); 

UPDATE

あなたがgetAsStringメソッドを使用し、バックスラッシュにしたいいけないかとデータ解析された取得したい場合は、

jreview.get("author_name").getAsString();

、私はバレーボールでStringRequestを使用してお勧めします。これからJSONArray、JSONObject、または必要なものとして扱うことができます。

注:応答がJSON配列であることを確認してください。私は(応答として示されているように)それがJSONObjectだと思います。したがって、StringRequestはここでより良いオプションになります。
