java - 将 JSONArray 转换为字符串数组

Question

我想问一个关于在 Android 上将 jsonArray 转换为 StringArray 的问题。这是我从服务器获取 jsonArray 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"}
]

如何将我必须的 jsonArray 转换为 StringArray，以便我可以像这样获得 StringArray:

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

感谢您的帮助:)

看看这个tutorial .你也可以像这样解析上面的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"));
}
