我使用CollapsingToolbarLayout
作为折叠工具栏,它在大多数情况下都有效。当您开始在RecyclerView
之外的页面的任何部分滚动时,它将滚动正常,工具栏将按照它应该的方式折叠。但是,当您开始在RecyclerView
上滚动时,它不会折叠工具栏并且看起来不是最好。
我尝试了许多我在网上找到的不同解决方案,似乎没有任何帮助。我正在使用appcompat-v7:23.2.1
。这是布局文件的样子:

对于RecyclerView,我将其设置为具有LinearLayoutManager和我的自定义适配器。任何帮助都会很棒,已经过了几个星期,我仍然无法解决这个问题。
编辑:似乎只在向上滚动时发生。如果工具栏折叠并向下滚动,它会像应该的那样展开。但是,和以前一样,向上滚动它似乎不起作用。
