Join David Gassner for an in-depth discussion in this video Using RelativeLayout containers, part of Android App Development Essential Training (2015).
- The RelativeLayout container is the other…most commonly used view group.…It lets you anchor objects to a container's edges…or to other objects within the container.…I'm using a project now called RelativeLayout,…and I've opened the content_main_layout file.…As before, I'll start by reformatting the code…so I can read it easily.…Notice in this file that the RelativeLayout…has padding settings for all four edges.…And they're all using the dimension resources,…which you can jump to by Control or Command clicking.…
And you will open the dimens.xml file.…If you were to change these values here,…you'd be changing not only this activity,…but any other layouts that are using these resources.…But, I'll leave them alone, and…come back to the content file.…I'm starting with the TextView control.…And I'm going to change the text that it's displaying…from "Hello World" to "First name:"…with a colon.…Now, I'm seeing a little bit of an error indicator.…And if I move the cursor over it,…I'll see a warning that I'm…hard-coding the string First name.…
