阅读更多关于 (Collapsing)Toolbar title resets its position after Snackbar appearance

Whenever a Snackbar is shown in the activity the title of the toolbar resets its position to the default expanded title position of the CollapsingToolbar even if the toolbar is not (fully) expanded. The second picture shows that the title is fixed no matter if the toolbar expands or not. The result is the same when I call snackbar.show() in activity or fragment . My layout structure looks like this: <CoordinatorLayout> <AppBarLayout> <CollapsingToolbarLayout> <Toolbar /> <TabLayout /> </CollapsingToolbarLayout>

阅读更多关于 Android appbarlayout elevation appears in status bar

How do I get rid of the elevation in the status bar? If I set in AppbarLayout the app:elevation to 0dp the elevation doesn't appear anymore in status bar but also not below the AppbarLayout. How do I just get the elevation under the AppbarLayout? Here's a screenshot of what I mean: puush link , notice the shadow in the status bar :( Thanks!
