将JSONArray转换为字符串数组
我想问一个有关将a转换jsonArray
为StringArray
on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 :)
回答:
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"));
}
以上是 将JSONArray转换为字符串数组 的全部内容, 来源链接: utcz.com/qa/431315.html
