将JSONArray转换为字符串数组

json

我想问一个有关将a转换jsonArrayStringArrayon的问题Android。这是我jsonArray从服务器获取的代码。

try {
    DefaultHttpClient defaultClient = new DefaultHttpClient();
    HttpGet httpGetRequest = new HttpGet("http://server/android/listdir.php");
    HttpResponse httpResponse = defaultClient.execute(httpGetRequest);

    BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(),"UTF-8"));

    String json = reader.readLine();

    //JSONObject jsonObject = new JSONObject(json);
    JSONArray jsonArray = new JSONArray(json);
    Log.d("", json);

    //Toast.makeText(getApplicationContext(), json, Toast.LENGTH_SHORT).show();

} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

这就是JSON

[
    {"name": "IMG_20130403_140457.jpg"},
    {"name":"IMG_20130403_145006.jpg"},
    {"name":"IMG_20130403_145112.jpg"},
    {"name":"IMG_20130404_085559.jpg"},
    {"name":"IMG_20130404_113700.jpg"},
    {"name":"IMG_20130404_113713.jpg"},
    {"name":"IMG_20130404_135706.jpg"},
    {"name":"IMG_20130404_161501.jpg"},
    {"name":"IMG_20130405_082413.jpg"},
    {"name":"IMG_20130405_104212.jpg"},
    {"name":"IMG_20130405_160524.jpg"},
    {"name":"IMG_20130408_082456.jpg"},
    {"name":"test.jpg"}
]

我怎样才能将我拥有的jsonArray转换为StringArray,这样我就可以得到StringArray:

array = {"IMG_20130403_140457.jpg","IMG_20130403_145006.jpg",........,"test.jpg"};

谢谢您的帮助 :)

看一下本教程。您也可以像上面这样解析json:

JSONArray arr = new JSONArray(yourJSONresponse);
List<String> list = new ArrayList<String>();
for(int i = 0; i < arr.length(); i++){
    list.add(arr.getJSONObject(i).getString("name"));
}
