I think could give it a look to the new UI Designer & Constraint Layout [LINK] in Android Studio 2.2 Preview, It may help to create your layout quickly and easily, just using drag and drop.

The problem is you are not using constraints at all which is the whole point of constraint layout. For example, if you don't use constraints on Download Brochure button and use only tools:layout_editor_absoluteX and tools:layout_editor_absoluteY attributes, the button stays at the position where you put it on the editor but when you compile the app, the button goes top left corner. You need to add those to Download Brochure button, then set its location. So it will be on the same position in every possible situation. app:layout_constraintLeft_toLeftOf="parent", app:layout_constraintRight_toRightOf="parent" But I suggest you to do it on editor while playing around with constraint layout which

The problem Thing is, I barely see any tutorials for it that could help me on this matter, other than the video presented on Google IO. What I am trying to do is, given that I have a vertically-centered LinearLayout within another layout - convert them both into a single ConstraintLayout. After all, this is the purpose of this new layout... The layout I wish to deal with looks like this: [LINK] Notice that the views in the center are only centered vertically, an

EDIT: This answer had been written before chains became available. Please use chains now, see above answer: [LINK] For now I believe your only choice would be to wrap the two text views in another layout - probably linear layout best fits this situation. But the team behind constraint layout said they want to introduce "virtual containers", which serve exactly this use case: you group two or more views together and set a constraint (like centring vertically) on the container. The idea is that it is not a full nested layout inside of constraint layout, but just something that constraint layout uses to position it's children - hence it should provide better performance than nesting.
