禁止ViewPager手势左右切换的操作：

public class ViewPagerEx extends ViewPager{
    private boolean isPagingEnabled = true;

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

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onInterceptTouchEvent(event);
    }

    public void setPagingEnabled(boolean canScroll) {
        this.isPagingEnabled = canScroll;
    }

    @Override
    public void setCurrentItem(int item, boolean smoothScroll) {
        super.setCurrentItem(item, smoothScroll);
    }
}

mViewPager.setPagingEnabled(false);//禁止左右滑动
mViewPager.setPagingEnabled(true);//开启左右滑动
