@mweiczorek I used this code to add alpha to a custom color:
.setMaskColour((ContextCompat.getColor(this, R.color.accent_color) & 0x00FFFFFF) | 0xdd000000)
.setMaskColor(Color.parseColor("#AARRGGBB")); // e.g. #d9000000 transparent black
Transparency is controlled by the alpha channel (AA in #AARRGGBB). Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent. Values in between are semi-transparent, i.e. the color is mixed with the background color
I want to set the color of the mask to a different color, but when I do, the mask is barely visible and the text is not legible being set against the underlying content (I'm using a dark theme for my app).
Is there a way to set the alpha transparency of the mask?
