WebKit Linear Gradient equivalent for Android (Java not XML)

Hi Guys,

You have the following code;

-webkit-linear-gradient(left, #64F6F6 51% , #FFF 51%);

If that was applied to a button it would look like half of the button is blue, half white, with no blending of the gradient between (a nice smooth line separating the colors).

First I want to be able to put this style on a button in Android via Java and not XML & then I will be changing the percentages every second.

I don't need help creating a method changing the percentage as I shall be doing this using runnable etc etc

What I would like to know is the syntax I need to use to put that exact gradient on the background of a button through Java(programmatically I think the term is called).

Then what would be the syntax to change the percentages inside the runnable.

i.e

// Change percentages on gradient MyButton.setBackground(awesomeGradient); // set new gradient to button background

I've looked at gradient drawables but I don't think I can access percentages nor achieve an "unblended " coming together of the colors.

In XML you can put a startcolor middle and end...so I'm sure java will have something.

Ideally if anyone has a simple approach that is like...webkit-linear etc....that would be awesome

Thanks

There's an answer on StackOverflow that might help: http://stackoverflow.com/a/8780181/475217

I haven't done this, so I don't know if this specific solution will give you exactly what you need, but the basic idea seems to match what you are looking for. Hope it helps!

Hi Ben,

Thanks for the reply

I found this there too but I don't really get how it works. Plus it seems like an awful lot of code for the CSS/ Javascript equivalent.

Also I have no idea how to set the shader to the background of a button :/ Or then access the "percentages" in a timer when I want to change the proportions of the colors.

Any ideas? :)
