Android：暂时禁用ScreenSlide功能

Question

我是编程的初学者，目前有点迷失。

我按照教程在我的应用中实现了滑动功能。它允许用户通过设置ScreenSlidePagerAdapter类来在两个片段之间滑动。

以下代码与ScreenSlidePagerAdapter

相关

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

    mPager = (ViewPager) findViewById(R.id.pager);
    mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
    mPager.setAdapter(mPagerAdapter);

}

@Override
public void onBackPressed() {
    if (mPager.getCurrentItem() == 0) {
        super.onBackPressed();
    } else {
        mPager.setCurrentItem(mPager.getCurrentItem() - 1);
    }
}

private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
    public ScreenSlidePagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public int getCount() {
        return NUM_PAGES;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Fragment createdFragment = (Fragment) super.instantiateItem(container, position);
        switch (position) {
            case 0:
                timerWindowReference = (TimerWindow) createdFragment;
                break;
            case 1:
                incentiveWindowReference = (SettingsWindow) createdFragment;
                break;
        }
        return createdFragment;
    }
}

我的问题： 我有一个按钮和onClick方法。如何在那里禁用和重新启用此Slider功能？
