Android第九讲——网络（六）xUtils

xUtils
需要导包。xUtils-2.6.14.jar
.result是返回的结果 GET POST
public class XUtilsActivity extends AppCompatActivity implements View.OnClickListener {    //使用注解去除findViewById    @ViewInject(R.id.button_xutils_get)    private Button mBtnXUtilsGet;    @ViewInject(R.id.textview_xutils)    private TextView mTextView;    @ViewInject(R.id.button_xutils_post)    private Button mBtnXUtilsPost;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_xutils);        ViewUtils.inject(this);//用注解去除findViewById后必须调用此方法    }    @OnClick({R.id.button_xutils_get, R.id.button_xutils_post})//注册点击事件（放在方法外边）    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.button_xutils_get:                utilDoGet();                break;            case R.id.button_xutils_post:                utilsDoPost();                break;            default:                break;        }    }    /**     * 用Post方法提交服务器     */    private void utilsDoPost() {        HttpUtils utils_Post = new HttpUtils();        RequestParams params = new RequestParams();//添加提交参数        params.addBodyParameter("username", "『唐』↹『人』");        utils_Post.send(HttpRequest.HttpMethod.POST, "http://192.168.***.*:8080/HTTpTest_Servelet/ServeletTest", params, new RequestCallBack() {            @Override            public void onSuccess(ResponseInfo responseInfo) {                mTextView.setText(responseInfo.result);//responseInfo.result表示返回的结果            }            @Override            public void onFailure(HttpException e, String s) {                mTextView.setText("网络连接错误");            }        });    }    /**     * 用Get方法向服务器提交数据     */    private void utilDoGet() {        HttpUtils utils_Get = new HttpUtils();        utils_Get.send(HttpRequest.HttpMethod.GET, "http://192.168.***.*:8080/HTTpTest_Servelet/ServeletTest?username=Queue", new RequestCallBack() {            @Override            public void onSuccess(ResponseInfo responseInfo) {                mTextView.setText(responseInfo.result);//responseInfo.result表示返回的结果            }            @Override            public void onFailure(HttpException e, String s) {                mTextView.setText("网络连接错误");            }        });    }}
