您需要的是JSON解析器。您可以使用多个库，例如Jackson或Gson。

这里用Gson处理一些基本的Json：

JsonObject json = new JsonParser().parse(myJsonString).getAsJsonObject();  // will parse your string to json and return it as a JsonObject
JsonObject data = json.get("data").getAsJsonObject(); // returns the jsonObject that contains everything in "data":{...}
JsonArray regions = data.get("regions").getAsJsonArray();  // to get an array like "regions"
for(int i=0;i<regions.size();i++){   // loop through the array
    JsonObject region = regions.get(i).getAsJsonObject();  // get any element in the array (as JsonObject)
    String text= region.get("text").getAsString();  // get a JsonElement from your JsonObject and read it as a String (like "text")
}

它看起来不太干净＆＃34;干净＆＃34;或者＆＃34;容易＆＃34;和其他Json图书馆会以不同的方式做到这一点，但如果你不想要整个＆＃34;数据＆＃34;我会推荐这种方式。要在POJO中解析的对象。你现在所要做的就是，用你向我展示的方法走过你的json，直到你得到＆＃34; url＆＃34;或者你想要的任何其他元素。
