Your best option is to use ConstraintLayout , like this: <?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android=" [LINK] " android:layout_width="match_parent" android:layout_height="match_parent" xmlns:app=" [LINK] "> <TextView android:id="@+id/greeting" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello" app:layout_constraintStart_toStartOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintTop_toTopOf="parent" app:layout_constraintBottom_toBottomOf="parent"/> </androidx.constraintlayout.widget.ConstraintLayout> Here is an excellent tutorial about ConstraintLayout : [this video]

you should keep in mind, that constraint layout is designed to be used in the 'Design' tab not in the 'Text' tab of the xml file. I'd recommend you to watch a tutorial like this one first: [this video]

Android studio does not work that way. You cannot set the positions of views(items) by dragging them and placing them. You will have to set the constraints on the attribute tab. You can find the attribute tab at the top left corner. It is visible in the picture you uploaded. Click on that and the attributes window will open. Then, when you click on a view, there is a square that appears in the attribute window. That square has 4 + signs around it. You have to click on one of the left or right + signs and enter a number. That would determine the horizontal position (distance from left or right margin) of the view. Similarly, set the vertical position by clicking on to our bottom + . This is t

If you want to stick to constraint layout, here's a quick tutorial which would make your basics strong for constraint layout: [this video] Quick tip: If you are focusing on getting constraints right, try to keep the layout(height and width) of buttons identical. for one of the buttons, you've used the code chunk: android:layout_width="0dp" android:layout_height="wrap_content" and for other button you've used: android:layout_width="156dp" android:layout_height="wrap_content" very important; consider chaining the items hard.

Maybe you should change the coordinatorLayout to a constraintLayout. If you set the toolbar height to wrap_content and the top constraint of the ViewFlipper to the bottom of the toolbar then the toolbar shouldn't cover the ViewFlipper Here is a youtube tutorial where you can dive deeper in constraint layouts: [this video] Credits: Coding in Flow Hope this helps?
