Is their a "region-like" folding feature for Android Studio

You can now do this:

<!--region Title--><View    android:layout_width="wrap_content"    android:layout_height="wrap_content"/><!--endregion-->

(I'm using Android Studio 3.0 and not sure when it was supported)

xml android-studio folding

Android Studio's XML editor supports only folding on IDE level with Cmd+Alt+"+" or "-".

xml android-studio folding

You can simply achieve this by

//region name~~~Code~~~//endregion
