Including One Layout in Another

Before we move on, I wanted to point out a cool feature of Android 0:00 layouts that I'm using in this app. 0:03 If you look at the activitysongplayback.xml file, 0:04 you'll notice that I have an interesting looking tag called include. 0:08 Although it isn't something that directly relates to styles and 0:11 themes, I wanted to share this cool trick as it's used a couple of times in the app. 0:13 And it's a great way to isolate layouts that are semantically similar. 0:17 To utilize the include tag, you simply have to declare your layout file in 0:20 one file, and you use the include tag in another layout that you want to use it in. 0:24 Then, specify the layout attribute with the name of the file your layout you'd 0:28 like to include was created in. 0:32 Now that you've got another cool Android trick under your belt, 0:38 I'm going to challenge you to extract another couple of styles for this app. 0:40 Try and see if you can create a style for 0:44 the song's playback time and the song's duration. 0:46 Then, if you want to go above and beyond, 0:49 try styling the album artwork with the rounded corners in the playback activity. 0:51 Come back when you're ready for my solution. 0:55
