关于Android Slidemenu的问题

Question

public class SlideMenu extends HorizontalScrollView{

private LinearLayout mWapper;
private ViewGroup mMenu;
private ViewGroup mContent;
private int mScreenWidth;
private int mMenuRightPadding;
private int mMenuWidth = 0;

private boolean once = false;

    DisplayMetrics metrics = new DisplayMetrics();

    mScreenWidth = metrics.widthPixels;
    //将dp转化为px
    mMenuRightPadding = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, SlideMenu.RIGHT_PADDING, context.getResources().getDisplayMetrics());
}

    }
}

 public class MainActivity extends Activity {
    //这个是声明一个自定义的那个控件
    private SlideMenu xcSlideMenu;
    //这个是声明页面上的头像的那个image控件的ID
    private TextView btnSwitch;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        setContentView(R.layout.activity_main);
        xcSlideMenu = (SlideMenu) findViewById(R.id.slideMenu);
        btnSwitch = (TextView)findViewById(R.id.btnSwitch);
        //给声明的image控件添加点击监听事件
        btnSwitch.setClickable(true);
        btnSwitch.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // 表示点击触发控件内部的右划和左划的事件
                xcSlideMenu.switchMenu();
                //btnSwitch.setVisibility(View.INVISIBLE);
            }
        });

    }

上面是相关的类
在主活动的界面中可以滑动，也可以按动btnSwitch来实现侧滑，想请教各位大神如何关闭手势滑动，而仅用按钮来实现滑动
