Layout File Storage

Shelby Swayze · Sep 1, 2019

I started a new app for a classroom tutorial video from Udemy.com on Android Studio. Now when I bring the app back and I have put a button, three editText boxes and three TextView boxes onto the layout, I can't bring the layout back and I can't find the layout file anywhere on my computer (at least so far). My question is: Does the layout file automatically save itself with Android Studio? With B4A android language's IDE, the layout file must be named and saved. I saw no prompt that I had to save or name the layout for my app ("Registration Form". Here's the app's Activity_main.xml code.

Code:

<?xml version="1.0" encoding="utf-8"?>

<resources xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent">
    <item name="workouttype" type="id" />
    <item name="txthello" type="id"/>
</resources>

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
