(When I saw the effect of the mask layer in the e-magazine, I thought it was very beautiful and troublesome. I searched a lot about the Android mask layer, but I didn't get any ideas. It turned out to be a transparent effect, and then it bounced out. Whether the control is transparent or translucent, you can choose a color, or \arbg, where a is the value of the legendary transparent color (you can set the transparent effect as needed). To say nothing more, send a simple demo, which is the effect of the magazine I copied: (because the magazine content is mainly pictures, and the pop-up layer is the text information given, I guess it is the magazine content displayed by the gallery.))
