我很难从这个文件中提取数据。我正在使用Volley发送请求和JSON来为我的Android应用程序提取这些材料。我能够获得第一个JSON数组，即name，id，place_id，phone等。但我无法从JSON数组中获取数据作为每个人的评论，weekday_text，照片等。所以请帮助我告诉我如何获得所需的信息。谢谢。

您可以使用JsonParser反序列化。我在下面写一个样本。但是我建议你用这种方式https://stackoverflow.com/a/2865580/1562723来让Gson对json进行deseriliaze。
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();
<强>更新
如果您不想使用反斜杠或想要使用getAsString方法获取解析数据，
jreview.get("author_name").getAsString();

你可能正在使用JSONrequest，我建议在Volley中使用 StringRequest 。从这里你可以得到你的响应字符串然后你可以把它当作JSONArray，JSONObject或任何你需要的。
注意：检查响应是否为JSON数组。我认为（如响应中所示）它是JSONObject。所以StringRequest在这里会更好。
