转换JSONArray到字符串

转换jsonArray到StringArray ，下面是我在服务器获取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();
}

JSON如下：

[{"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"}]

应该怎么转换jsonArray
array = {"IMG_20130403_140457.jpg","IMG_20130403_145006.jpg",........,"test.jpg"};
