android - Using alpha mask on TextView removes parent view alpha as well? -


i'm trying have textview alpha linear gradient applied it, this:

enter image description here

i have implementation works, here's code:

public class mytextview extends textview {      paint paint = new paint();      void init() {         paint.setalpha(0xffffffff);         paint.setxfermode(new porterduffxfermode(porterduff.mode.overlay));          paint.setshader(             new lineargradient(                 0, 0, getwidth(), getheight(),                  0xffffffff, 0x00000000,                  shader.tilemode.clamp));     }      void draw(canvas canvas) {         super.draw(canvas);          canvas.drawrect(0, 0, getwidth(), getheight(), paint);     } }

it sits in layout, has own translucent background:

<view background="#33000000">     <mytextview /> </view>

the paint mode seems remove translucent background color of parent view. i'm not sure how stop draw code in textview class affecting background color of parent view?

thanks
