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;

    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:
