java - 在android中将json读取为字符串对象

Question

我已从 URL 中读取 JSON 数据作为字符串对象，并将其(作为字符串对象)传递给我的第二个 Activity 。如何从该字符串对象读取值？请帮助我。

下面是我的 json:

{
    "speciality": [
        {
            "id": "1",
            "d_name": "Dr.Steven Cohen",
            "file_upload": "dr-photo.png",
            "d_address": "3838 California St. San Francisco,CA 94118",
            "d_specialty": "Eye",
            "designation": "Ophthalmologist",
            "d_city": "San Francisco",
            "d_state": "Calfornia",
            "d_zipcode": "CA94118",
            "d_phone": "018  000  000",
            "latitude": "18.815427",
            "longitude": "76.775144"
        },
        {
            "id": "2",
            "d_name": "Dr.  Hanish Patel",
            "file_upload": "hanish-patel.jpg",
            "d_address": " 160  East 56th Street New York, NY 10022 ",
            "d_specialty": "Eye",
            "designation": "Optometrist",
            "d_city": "New York",
            "d_state": "United States",
            "d_zipcode": "NY 10022",
            "d_phone": "018 000 000",
            "latitude": "40.760407",
            "longitude": "-73.968694"
        },
        {
            "id": "3",
            "d_name": " Dr. Leonard Bley MD, FACS ",
            "file_upload": "leonard-bley.jpg",
            "d_address": " 160 East 56th Street New York, NY 10022",
            "d_specialty": "Eye",
            "designation": "Ophthalmologist",
            "d_city": "New York",
            "d_state": "United States",
            "d_zipcode": "NY 10022",
            "d_phone": "018 000 000",
            "latitude": "40.760407",
            "longitude": "-73.968694"
        },
        {
            "id": "4",
            "d_name": "Dr. John Selle",
            "file_upload": "john_selle.jpg",
            "d_address": "2250 Hayes St Ste 206 San Francisco, CA 94117",
            "d_specialty": "Eye",
            "designation": "General  Practitioner",
            "d_city": "San Francisco",
            "d_state": "Calfornia",
            "d_zipcode": "CA94118",
            "d_phone": "018 000 000",
            "latitude": "37.78604",
            "longitude": "-122.457639"
        }
    ]
}

这是我的代码:

try {
    JSONObject mainObject = new JSONObject(strjson);
    //JSONObject uniObject =         mainObject.getJSONObject("speciality");
    //JSONObject  uniName = uniObject.getJSONObject("d_name");
    //JSONObject uniURL = uniObject.getJSONObject("d_address");

    JSONObject oneObject = mainObject.getJSONObject("d_name");

    Log.e("name:", "unique name" + oneObject);
} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}

}

试试这个......

      JSONObject mainObject = new JSONObject(strjson);

      JSONArray Array = mainObject.getJSONArray("speciality");
        for (int j = 0; j < Array.length(); j++) 
        {   
            if (Array.getJSONObject(j).has("id")) 
            {
                String str1 = (Array.getJSONObject(j).getString("id"));
                String str2 = (Array.getJSONObject(j).getString("d_name"));
              Log.e("TA","name:"+str2);
             }
        }
