问题
For my application I have to draw a bitmap on top of the Navigation bar on the bottom of the android screen. I am curious to know if the WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY can be used to overlay the navigation bar?
回答1:
Use the WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS should work :)
