注：首先在AndroidManifest.xml中设置联网，然后导包，写Bean包

public class MainActivity extends Activity {

   String path = "http://web.juhe.cn:8080/constellation/getAll?consName=白羊座&type=year&key=3ac9f31ff66b9746539472887b3799c3";

   Handler handler = new Handler() {

       public void handleMessage(android.os.Message msg) {

           Bean bean = (Bean) msg.obj;

           System.out.println(bean.toString());

           tv.setText(bean.toString());
       };

   };

   private TextView tv;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);

       tv = (TextView) findViewById(R.id.tv);

   }

   // 请求数据按钮
   public void send(View v) {

       new Thread() {

           public void run() {
               getData();
           };

       }.start();

   }

   /**
   * 联网的方法
   */
   protected void getData() {

       // /得到HttpClient对象
       HttpClient httpClient = new DefaultHttpClient();
       // 得到连接方式对象,设置请求路径
       HttpGet httpGet = new HttpGet(path);

       try {
           // GET方式请求接口,得到响应内容
           HttpResponse httpResponse = httpClient.execute(httpGet);

           // 得到状态行
           StatusLine statusLine = httpResponse.getStatusLine();
           // 得到状态码
           int statusCode = statusLine.getStatusCode();
           // 如果状态码等于200,代表请求成功
           if (statusCode == 200) {
               // 得到包含着数据的实体
               HttpEntity entity = httpResponse.getEntity();
               // 讲实体转换成String,并设置编码集
               String data = EntityUtils.toString(entity, "UTF-8");
               // System.out.println(data);
               // 解析json
               Gson gson = new Gson();
               Bean bean = gson.fromJson(data, Bean.class);
               Message msg = Message.obtain();
               msg.obj = bean;
               handler.sendMessage(msg);

           } else {

               Toast.makeText(MainActivity.this, " 请求失败 ", 1).show();

           }

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

   }
}
