安卓解析从后台获取到的json

后台获取到的json是{"status":"ok","data":[{"id":2,"name":"李四","passwd":"123456"},{"id":1,"name":"张三","passwd":"123456"}}
public void execute(String result){
JSONObject object=new JSONObject(result);
//下面怎么写？？？
}
请问如何能获取到status、data和data中的值？？
拜托拜托~

import java.util.List;

ArrayList list=new ArrayList<>();

//解析json

JSONObject object=new JSONObject(json);
String a=object.optString("status");
Toast.makeText(MainActivity.this,"status:"+a,Toast.LENGTH_SHORT).show();
JSONArray array=object.optJSONArray("data");
for (int i=0;i<array.length();i++){
bean one=new bean();
JSONObject jsonObject = array.optJSONObject(i);
one.id=jsonObject.optInt("id");
Toast.makeText(MainActivity.this,"id:"+one.id,Toast.LENGTH_SHORT).show();
one.name=jsonObject.optString("name");
Toast.makeText(MainActivity.this,"name:"+one.name,Toast.LENGTH_SHORT).show();
one.passwd=jsonObject.optString("passwd");
Toast.makeText(MainActivity.this,"passwd:"+one.passwd,Toast.LENGTH_SHORT).show();
list.add(one);
}

}

直接用Gson,依赖一下,很方便的

public static void main(String[] args) throws Exception {

    String str = "{\"status\":\"ok\",\"data\":[{\"id\":2,\"name\":\"李四\",\"password\":\"123456\"},{\"id\":1,\"name\":\"张三\",\"password\":\"123456\"}]}";
    JSONObject json = new JSONObject(str);
    System.out.println("status:" + json.getString("status"));
    JSONArray jsonArray = json.getJSONArray("data");
    for (int i = 0; i < jsonArray.length(); i++) {
        System.out.println("id:" + jsonArray.getJSONObject(i).getInt("id"));
        System.out.println("name:" + jsonArray.getJSONObject(i).getString("name"));
        System.out.println("password:" + jsonArray.getJSONObject(i).getString("password"));
    }

        System.out.println("name:" + jsonArray.getJSONObject(i).getString("name"));
        System.out.println("password:" + jsonArray.getJSONObject(i).getString("password"));
    }

}

。。。
