简单的android网络请求

请求数据来源：
https://api.douban.com/v2/movie/top250 params： start，count
OK+AsyncTask

//对ok的简单设置
public class MyOkhttp {
    public static OkHttpClient client = new OkHttpClient();
    public static String get(String url){
        try {
         client.newBuilder().connectTimeout(10000, TimeUnit.MILLISECONDS);
        Request request = new Request.Builder().url(url).build();
        Response response = client.newCall(request).execute();
        if (response.isSuccessful()) {
            return response.body().string();
        } else {
            throw new IOException("Unexpected code " + response);
        }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
    }
}

//很简单请求网络字符串
public class NetTest extends Activity {
    private TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_net);
        tv = ((TextView) findViewById(R.id.tv));
        new GetData().execute("https://api.douban.com/v2/movie/top250");
    }
    /**
     * 参数：url，progress，result
     */
    private class GetData extends AsyncTask<String,Integer,String>{
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }
        @Override
        protected String doInBackground(String... strings) {
            return MyOkhttp.get(strings[0]);
        }

        @Override
        protected void onPostExecute(String s) {
            super.onPostExecute(s);
            tv.setText(s);
        }
    }
}
