我的项目中有GSON库，我需要ext_id。我可以使用 JSON.get("images") 访问“图像”，但是我无法进入图像数组。有人可以帮我解决这个问题吗？

最佳答案
你可以试试这个。
public void parse(String jsonString) {
JsonElement jelement = new JsonParser().parse(jsonString);
JsonObject jobject = jelement.getAsJsonObject();
JsonArray jarray = jobject.getAsJsonArray("images");
for(int i=0;i<jarray.size();i++){
JsonObject jsonObject = jarray.get(i).getAsJsonObject();
String result = jsonObject.get("ext_id").toString();
System.out.println(result);
result = jsonObject.get("height").toString();
System.out.println(result);
}
}
