java - ViewPager 卡住了

Question

我在我的应用程序上使用了一个 View 分页器，里面有多个 fragment ，我还使用这些代码禁用了我的 View 分页器滑动，但在我的布局“fragment_hr_link.xml”中，我可以滑动它，但它卡在两个 fragment 之间

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

它在我的一些 fragment 中工作正常，但是，我对此布局有问题，滑动工作正常，但卡住了

你有一个不应该是可滑动的viewpager？

尝试像这样制作自定义 View 页面:

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;
    }
}

您还可以查看 Android 架构组件中的新 viewPager2: https://developer.android.com/reference/androidx/viewpager2/widget/ViewPager2 https://developer.android.com/training/animation/vp2-migration

希望这有帮助;-)
