Define and load parameters for LinearGradient from XML

Question

Instead of programatically passing parameters to create a LinearGradient.

new LinearGradient(0, 0, 0, mWheelHeight, Color.parseColor("#4A90E2"), Color.parseColor("#50E3C2"), Shader.TileMode.MIRROR);

is it possible to load the colors from XML?

Well you can set this by use of android:background="@drawable/gradient.xml" — Sanjeev, Jul 17 '15 at 05:28
I want to set this as the shader for the Paint instance for drawing shapes. — ksuralta, Jul 17 '15 at 05:29
Not with xml but see http://stackoverflow.com/questions/8600805/how-to-set-gradient-style-to-paint-object http://stackoverflow.com/questions/2836098/how-to-fill-a-path-in-android-with-a-linear-gradient — Toris, Jul 17 '15 at 05:40
I don't think your xml means a `LinearGradient`, it's a `Shape`. — SilentKnight, Jul 17 '15 at 06:06
`"I have defined a gradient in xml."` no, you have created a `Drawable`, not a "gradient" so you cannot convert it to a `Shader` — pskink, Jul 17 '15 at 06:54

You can set this directly inside Paint

paint.setShader(new LinearGradient(0, 0, 0, getHeight(), Color.BLACK, Color.WHITE, Shader.TileMode.MIRROR));
