ViewPager如何中断滚动

public class CustomViewPager extends ViewPager {
    private boolean isScrollEnabled = true;

    public CustomViewPager(Context context) {
        super(context);
    }

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (this.isScrollEnabled) {
            return super.onTouchEvent(event);
        }
        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.isScrollEnabled) {
            return super.onInterceptTouchEvent(event);
        }
        return false;
    }

    public void setScrollEnabled(boolean scrollEnabled) {
        this.isScrollEnabled = scrollEnabled;
    }
}
