Android 禁止Viewpager左右滑动功能

Posted 2022-01-28 derekhan

做项目要求某种情况下ViewPager不能滑动

百度后发现重写ViewPager，覆盖ViewPager的onInterceptTouchEvent(MotionEvent arg0)方法和onTouchEvent(MotionEvent arg0)方法，这两个方法的返回值都是boolean类型的，只需要将返回值改为false，那么ViewPager就不会消耗掉手指滑动的事件了

public class NoScrollViewPager extends ViewPager 
    
    private boolean noScroll = false;
 
    public NoScrollViewPager(Context context, AttributeSet attrs) 
        super(context, attrs);
    
 
    public NoScrollViewPager(Context context) 
        super(context);
    
 
    public void setNoScroll(boolean noScroll) 
        this.noScroll = noScroll;
    
 
    @Override
    public void scrollTo(int x, int y) 
        super.scrollTo(x, y);
    
 
    @Override
    public boolean onTouchEvent(MotionEvent arg0) 
        if (noScroll)
            return false;
        else
            return super.onTouchEvent(arg0);
    
 
    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) 
        if (noScroll)
            return false;
        else
            return super.onInterceptTouchEvent(arg0);
    
 
    @Override
    public void setCurrentItem(int item, boolean smoothScroll) 
        super.setCurrentItem(item, smoothScroll);
    
 
    @Override
    public void setCurrentItem(int item) 
        super.setCurrentItem(item);
