阅读更多关于 How to make the overflow popup menu avoid obstructing the action bar?

Background On my app , when I've updated to the new support library and also tried on Lollipop, I've noticed a weird issue: when clicking on the overflow button of the action bar (or even the new Toolbar class) will show the popup menu on top of the action bar, hiding other action items, as such: Here, the action items that got hidden are uninstallation and sharing. The problem I've tried to avoid this issue, by ovverriding the style of the overflow menu, but nothing has helped. Not only that, but it seems this is an intentional behavior , yet in many Google apps that were updated to have

阅读更多关于 CollapsingToolbarLayout crash on 4.4 devices (java.lang.IllegalArgumentException: radius must be > 0)

问题 I have implemented the new style Collapsible Toolbar. I am using the same code as the example (Cheesesquare) demo app - which of course works fine on all devices. I need help figuring out what I am doing different then the sample (so my app won't crash). My app runs great on 5.0+ devices, but crashes on older devices (OS 4.4.4) with an error that I can't isolate to my code (no references to my project's classes in the stack).

阅读更多关于 How to specify dark action mode with my theme

问题 I know there are a couple of questions about styling the contextual action bar (ActionMode) piece of the action bar, but they don't quite seem to address what I'm after. I'm using the Toolbar with a light theme and dark action bar. The Toolbar looks like I want it, but the action mode looks like the regular dark theme. What do I need to change in my style to get the dark themed action mode (not just action bar)? It seems I should be able to do this quickly by tapping into Theme.AppCompat
