如题！

最近在升级项目的 targetSdkVersion 到了 31，androidx.fragment 到了 1.3.6。
发现当 pop 横向返回的时候，动画问题很大，请帮忙确认一下？万分感激。

很高兴大佬接手这项目。
我遇到了下面的问题：

A Activity页面有ViewPager+4个fragment
B Activity页面只有一个按钮

先打开A再打开B页面，点击按钮，通过类似EventBus这一类总线告知A页面，切换Viewpager的位置，然后点击返回A页面，发现切换后新的fragment页面是没有调用到supportVisible函数的，onLazyLoad更没有。

在多此尝试后，发现这是跟fragment是否在offscreenPageLimit缓存范围内有关的，如果在缓存范围外，切换Viewpager后可以调用到supportVisible函数，在缓存范围内就不能调用到。

目前我是自己重写setUserVisibleHint等来实现切换监听的，不知道我这样使用fragmentation对不对

多处需要跳转到同一个地方，想在跳转的代码里获取当前fragment或者ParentFragment实例来start()，请问如何获取呢。

滑到一半，取消侧滑，再点击返回键，右边会出现空白。
原因：添加 api ### ### 'androidx.lifecycle:lifecycle-extensions:2.2.0'这个库，版本是2.2.0时，是必现的，请问有没有什么解决办法

我看到Fragmentation中是通过getUserVisibleHint判断是否可见的，但是ViewPager1最新版和ViewPager2是通过setMaxLifecycle控制fragment可见性的。
目前我测试了下，ViewPager2中放置了Fragment，一打开会把ViewPager上所有的supportVisible()都调用了，而不是滑倒那一页才调用。旧版的ViewPager使用getUserVisibleHint判断方式，则不会有这个问题，滑动到那一页才会调用其supportVisible()。
不知道有没有大佬有没有高招兼容下。

在demo的wechat模块中，连续启动多个CyclerFragment后，然后侧滑返回，会直接回到初始的fragment，而不是一级一级逐步返回

建议使用OnBackPressedDispatcher实现该功能。startXXforResult建议使用registerForActivityResult。都是androidX提供的。

想问下为什么 pop函数里面（包括popTo）都有一个先remove再 popBackStack的逻辑，这里只做popBackStack 应该就有remove的效果，一直没看明白是为什么，求大佬解惑

无法下载

作者大大以及各位小伙伴，我的项目中，首页底部用了Tab，用loadMultipleRootFragment加载多个同级根Fragment。
其中一个Fragment是购物车，当用户没有登录的时候，我点击这个购物车的tab，需要先跳到登录页，登录完成后再进入这个购物车的Fragment。
AccountHelper.getInstance().doLoginIfNeed(MainFragment.this, new AccountHelper.OnLoginHandler() {
@OverRide
public void next(SupportFragment currentFragment) {
showHideFragment(mFragments.get(position));
}
});
但是登录完成，登录页finish掉，执行 showHideFragment(mFragments.get(position));进入购物车fragment的时候，页面卡主了，打印发现购物车fragment的onSupportVisible（）这个方法没有执行。
请问这个问题咋解决呢，有遇到的小伙伴看到了也麻烦告诉我一下，非常感谢。

是这样的，我想实现全屏能滑动关闭页面，然后设置了setEdgeLevel(SwipeBackLayout.EdgeLevel.MAX);
（ps：原作者好像说不推荐设置MAX，但是今日头条，YouTube这些都是全屏可以关闭的）

这样生效了，但是也产生了新的问题：就是我左手大拇指下滑时，总是被误判为开始拖动关闭；右手大拇指上滑时，也会被误判为拖动关闭。

找了很久，我也始终没有找到设置灵敏度的接口，所以希望看能不能加一个这样的接口呢？

java.lang.ClassCastException: android.view.View cannot be cast to android.view.ViewGroup

线上报的错，问题应该是出在这一段代码里。然后出问题的Activity是一个简单的页面，没有额外添加View。设备也很统一，90%都是三星的手机

我看了一下原作者的代码

private void enqueueDispatchVisible() {
        taskDispatchSupportVisible = new Runnable() {
            @Override
            public void run() {
                taskDispatchSupportVisible = null;
                dispatchSupportVisible(true);
            }
        };
        getHandler().post(taskDispatchSupportVisible);
    }

这里是直接post了一条任务
你的这个方法是这样的

private void enqueueDispatchVisible() {

       mIdleDispatchSupportVisible = new MessageQueue.IdleHandler() {
           @Override
           public boolean queueIdle() {
               dispatchSupportVisible(true);
               mIdleDispatchSupportVisible = null;
               return false;
           }
       };

    Looper.myQueue().addIdleHandler(mIdleDispatchSupportVisible);

}

是用空闲任务去调用dispatchSupportVisible，但是有时候不走回调导致我的fragment生命周期的onSupportVisible不执行，请问我要怎么处理

大佬，这种问题请您能不能告诉下怎么定位？
我是修改的以前同事的项目，他用的YoKeyword的fragment开源库，fragment的adapter是在线资源，我换了在线资源，fragment就显示不出来，fragment的onSupportVisible有被回调。

解决sdk升级29的问题.

• Library version :29

**我用这个库半年了,看到作者停止维护,就想拉下来,自己维护,在原作者issues中看到你在接任维护,我想把sdk升级到29,发现报错了,FragmentManagerImpl这个类非public,原作者写的FragmentationMagician无法访问FragmentManagerImpl,于是乎去找答案,没找到,自己折腾了一上午,终于搞定了,就是把AndroidX中FragmentManagerImpl源代码完全复制一份,新建一个一模一样的包名,效果如下图所示.最后能正常跑起来,暂时没发现什么bug..大佬既然有心维护,能不能建个群一起交流讨论,这个库真心挺好用的. 上个issure中的setMaxLifeCycle,是新api,getUserVisibleHint确实已经废弃了,那么FragmentManagerImpl可以自己复制,是不是可以想想办法,应用到setMaxLifeCycle呢?

需要弹出多个Fragment时，调用popTo崩溃，提示Fragment ... has not been attached yet.
