ViewPager卡住

Question

我在应用程序中使用视图分页器，内部有多个片段，我也使用这些代码禁用了viewpager滑动，但是在我的布局'fragment_hr_link.xml'中，我可以滑动它，但是卡在了两个片段之间

viewPager.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return true;
        }
    });

它在我的某些片段中工作正常，但是我在此布局上遇到问题，滑动有效，但卡住了

您有一个不应滑动的Viewpager？

尝试使您的自定义Viewpager像这样：

public class SwipeDisabledViewPager extends ViewPager {

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

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

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        // returning false will not propagate the swipe event
        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return false;
    }
}
