Question

I have a problem. I would like to have a textview with a gradient as color. And a black shadow behind it. The problem is that the shadow is using the color of the gradient in stead of using the called color (Color.BLACK)

My code is:
numberTextView = (TextView)findViewById(R.id.something);

    Shader textShaderTop = new LinearGradient(0, 30, 0, 60,
                new int[]{Color.parseColor("#A6A6A6"), Color.parseColor("#E8E8E8"), Color.parseColor("#A6A6A6")},
                new float[]{0, 0.5f, 1}, TileMode.CLAMP);
    numberTextView.getPaint().setShader(textShaderTop);

    numberTextView.setShadowLayer(
              0.1f,   //float radius
              20f,  //float dx
              20f,  //float dy 
              Color.BLACK //this is not black on the screen, but it uses the gradient color!?
              );

Does anybody knows what to do

I had exactly the same problem.
I managed to fix it by extending TextView and overriding onDraw method.
Here is how it looks like

@Override
protected void onDraw(Canvas canvas) {
    // draw the shadow
    getPaint().setShadowLayer(1, 1, 1, 0xbf000000); // or whatever shadow you use
    getPaint().setShader(null);
    super.onDraw(canvas);

    // draw the gradient filled text
    getPaint().clearShadowLayer();
    getPaint().setShader(new LinearGradient(0, getHeight(), 0, 0, 0xffacacac, 0xffffffff, TileMode.CLAMP)); // or whatever gradient/shader you use
    super.onDraw(canvas);
}

However this method probably won’t work if you want to use colors with transparency in your gradient.
