如何从android中的json响应中获取值？

Question

我面临一些问题，要从我的json响应中获取价值。我的Json回复如下：

{
    "changed": [
        "username",
        "phone",
        "profile_picture",
        "public_ind"
    ],
    "failed": []
}

请有人给我一些线索，以便我可以从我的JSON响应中获得价值。

Answer 1

试试这个：

JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArrayChanged = jsonObject.getJSONArray("changed");
String failed = jsonObject.getString("failed");
for(int i=0;i<jsonArrayChanged.length();i++){
String str = jsonArrayChanged.getString(i);
} 

Answer 2

//first parse your root object from json string
JSONObject rootObject = new JSONObject(Sring_data);

//get the json array object
JSONArray changedFields = rootObject.getJSONArray("changed");

//iterate the array object
for (int i = 0; i < changedFields.size(); i++) {
Log.d("", changedFields.getString(i)); //here you will get each array items
}

// parse other json objects other than json array
String failedObj = rootObject.getString("failed");
