Android Layout Files
The Android platform uses XML layout files to define the user interface.
Elements uses these standard files in the same way they are used when working with the Java Language, so Elements developers have access to the same controls and UI capabilities as all other Android developers, fully natively.
You can edit these XML files directly using the regular code editor, or you can ask Fire or Visual Studio to launch Android Studio to design these files using Google's official visual designer, by right-clicking the project node in the Solution tree and choosing "Edit User Interface Files in Android Studio" (Fire) or "Open in Android Studio" (Visual Studio).
