I'm using constraint layout inside Scroll View layout, I tried various text alignment, widget alignment but the layout still remains to align left.

I Have Used Linear Layout And Updated Your Code to look like a form

What I would suggest you to do is to fit everything into a Linear Layout, like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
your code here
</ScrollView>
</LinearLayout>
Also, as someone said in your comments, you should, inside of the ScrollView, use LinearLayout with vertical alignment, and then use proper paddings and margins in order to make the UI look good. You can use gravity and layout-gravity to align every element you want.

And this is my physical devices unexpected output:-
I don't understand why this output act like that and which is totally unexpected. how I resolve this issue.

Since your CardView is not constrained by the buttons at the bottom the CardView will take space beyond those buttons. In the screenshot provided from a real device, it is clear that there is not much space to completely accommodate the contents in the CardView hence it will be pushed beyond the button. You need to add constraints to CardView to align it with the bottom button also you need to add a ScrollView if there is more content that the screen can't fully accommodate. Using this layout may improve the UI

How to let user add new plain texts in Android Studio?

I'm working on this project with my classmates, and we decided to do a recipe app. I'm working on the create recipe screen. Instead of adding multiline text for the instructions, I added plain text(1 for each instruction) just so that the appearance of all the recipes will be consistent. At first, it will start of with one instruction and then I want the user to be able to add more from then on.
here's the xml :

I originally thought I would be able to write to the activity_main.xml using the MainActivity.java, but apparently the xml files are read-only. I know the answer sounds obvious after typing that, but is there a way to dynamically change the layout?

What you want is to create a dynamic list with a RecyclerView. There are some sample apps at the bottom to help you get started.
If you have any questions after reading feel free to edit your post or create another one.

RecylerView is the correct way to do it . But since you are a beginner to android i presume use ArrayAdapter for any list like elements.
"change the layout dynamically" is a bit broad but use
// view is any element in your code
view.visibility = View.Visible
view.visibility = View.GONE
XML based layout works on events ..what i mean by that is something happens when you interact . So for example if you want an image to disappear on the click of a button you would do something like
view.setOnCLickListener{
imageview.visibility = View.GONE
}

How do i get rid of this gap between the toolbar and the recycler view?

I am a beginner in native android programming. Would like to seek some guidance and help to get rid of this gap in between the toolbar and my recycler view. Read through some write-ups on people who faced the same issue but majority of these had included a "Coordinator Layout" or "layout_gravity". However, I did not have those in my code. Tried many other ways but couldn't make it work.
Here is a picture that is based on the code! The embedded picture shows a better contrast for the gap. Sorry my account doesn't allow any embedding of photos yet.
Here is my code for the parent recycler view.

put your views in scrollView like below:

To scroll your screen you simply need to do put a ScrollView inside your layout, like that:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

</ScrollView>
If it says ScrollView can only have one child. Put the children in a single Layout like LinearLayout.
