Answer 1

I wrote a Shape, just set the solid to white

Answer 2

This is related to the Android version and Rom... If you use the system's default style, different effects may appear on different machines.
Tried before: EditText, set the font to white. On Sony, the background of EditText is black, but on Xiaomi, the background is white, and the subtitles in EditText cannot be seen clearly.
Therefore, if you are making that kind of released product, it is best to customize each module to maintain the same effect on different phones, different versions, and different ROMs.
