Android访问php取回json数据

PHP代码：

$array = array(
'username'=>'杨铸',
'password'=>'123456',
'user_id'=>1
);
echo json_encode($array); 

java代码：

private void startUrlCheck(String username,String password)
{
 HttpClient client = new DefaultHttpClient();
  StringBuilder builder = new StringBuilder();

  HttpGet myget = new HttpGet("http://10.0.2.2/Android/index.php");
 try {
   HttpResponse response = client.execute(myget);
    BufferedReader reader = new BufferedReader(new InputStreamReader(
   response.getEntity().getContent()));
    for (String s = reader.readLine(); s != null; s = reader.readLine()) {
      builder.append(s);
    }
   JSONObject jsonObject = new JSONObject(builder.toString());
   String re_username = jsonObject.getString("username");
    String re_password = jsonObject.getString("password");
    int re_user_id = jsonObject.getInt("user_id");
    setTitle("用户id_"+re_user_id);
   Log.v("url response", "true="+re_username);
   Log.v("url response", "true="+re_password);
 } catch (Exception e) {
   Log.v("url response", "false");
   e.printStackTrace();
  }
}

说明：


其中http://10.0.2.2为Android访问本机url的ip地址。对应电脑上测试的http://127.0.0.1

此为应用访问网络的权限不足 在AndroidManifest.xml中，需要进行如下配置：

就加在

之前就好了
然后测试通过。
