Android运动布局无法相应工作
我不熟悉Android运动布局无法相应工作,android,android-constraintlayout,android-transitions,android-motionlayout,Android,Android Constraintlayout,Android Transitions,Android Motionlayout,我不熟悉motionlayout，一直在关注各种在线教程，希望了解它的工作原理。简而言之，我知道它基本上是为约束集设置动画，你有一个开始和结束，你可以用约束集进一步定制。我有这个布局 我想模仿Lyft的底片 在我的布局中，你要去哪里按钮会随着搜索目的地文本输入淡入而慢慢淡出。底部的recyclerview假设保存了地址，则不会受到影响。我使用标准的底片尝试了这个实现，但是在动画方面遇到了挑战，它有一个奇怪的闪烁，所以我决定使用一个正常视图的运动布局 我的底页布局如下 <com.goog

当我启动这个应用程序时，我无法让底部滑动，它根本没有任何反应。但我注意到的一件事是，在添加了app:layoutDescription=“@xml/taxi\u bottomsheet\u scene”
属性后，底部工作表大小更改为我在constraintSetStart
中指定的大小，但addressViews
视图没有更改
所以我的布局看起来像
所以我的问题是，如果我的底部表单没有响应我的滑动
，并且地址视图
在初始状态下消失，我会出什么问题呢？我最终设法使它工作，包括运动布局
和协调布局
。我将只发布协调人
解决方案，因为它很长，而且我没有时间，如果有人需要，请发表评论，我将发布
我创建了3个布局，1。带有地图的主布局
，2。顶部带有“收件人”和“发件人”地址编辑文本的栏
和3。向上滑动并显示顶部栏的底部布局
使用协调布局的解决方案1
顶栏
请注意，我在顶部地址栏上使用了不可见的而不是消失的？这是因为每次我调用GONE
时，根据我的假设，理想情况下布局都会重新计算
，地图会闪烁，为了停止，我不得不使用“不可见”，因为布局没有收缩，相反，它仍然占用相同的空间，但只是不可见
另外请注意，我正在添加paddingcardChooseAddressBottomSheet.getLayoutParams（）
这是因为我需要工作表不要深入到topAddressBar
下面，以免隐藏我的recyclerview内容。当前的填充确保recyclerview完全可见，并且它上面的所有其他内容都位于topAddressBar
下面。您是否修复了它？我也在处理同样的情况。但不是用动作布局是的，我做了。我会很快发布答案。好的。谢谢谢谢。@shine_joseph我用MotionLayout
和coordinatorlayout
都达到了同样的效果。MotionLayout使MapFragment
闪烁，但CoordinatorLayout
方法不闪烁。我应该提供哪一个？你可以提供最好的。嗨，你能分享MotionLayout解决方案吗？或者，如果您的代码位于github，您也可以共享github链接。谢谢@AstonioCheck@K.tas
