问题 As my question suggests, I am trying to figure out how to set my status bar color transparent while keeping my navigation bar black/natural color (without affecting the screen height) I referred to this site : Android Completely transparent Status Bar? one of the solutions that partially worked was : getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); but that pushes my screen content below navigation bar making it

Please provide me with a step by step instructions to help me solve this problem or a copy of a manifest that is compatible. (I have already looked for some opensource apps and they provide none of these tags

问题 I'm trying to scale a textView inside a container view. Activity uses a motion layout. I can scale the textView if I don't place it inside the container. Here is my activity layout and the motion layout description file. How can I make scaleX and scaleY work?
