However that has all changed and we now have gradient support in API24 and later. First let’s take a look at a simple example and then we will recreate a gradient as can be seen in the Spotify app/website. To provide a sense of depth, treatments are applied to the top and bottom edges of elements. In the previous post we have created a blue actionbar header. This chapter also covers the tips to make a better UI design and also explains ho Drag right/bottom/corner to … There are a few different modes here to choose from, if you are interested in what these are, a great explanation of Porter/Duff blend modes can be found here.

As you can see above, the two images should perfectly overlay. Another issue is that they took a bit longer to draw than a Bitmap since there is a lot of parsing and drawing going on behind the scenes. If you have used XML to define your shape, you can use getDrawable method in Java to get the reference to your shape.

Other types are radial and sweep. In the example above, the packager will look for my-icon.png in the same folder as the component that requires it. The code for this is below. In this example, we are creating the shadow at the bottom of the button and an offset of 4px. Advanced Box size. Then we will create some Drawables that could be used in your app and lastly for the grand finale we will try to replicate a gradient as can be seen in the Spotify app/website.
