And this is what I want
Only the buttons. Here is my XML for the corresponding issue.

The smaller button is btnSendPassword and the other button is btnActive. I've tried playing with the widths but nothing changed. I'm fairly new so any explaination why this is happening would be good, so then I know whats wrong if it happens again.Any help would be wonderful.

You should align your btnSendPassword button with rlSignInForm for both left and right...then you will achieve your requirement. Replace the following XML snippet of btnSendPassword with your existing XML snippet of btnSendPassword...you will get all the problem solved.
<Button
android:id="#+id/btnSendPassword"
android:layout_width="175dp"
android:layout_height="55dp"
android:layout_below="#+id/rlSignInTitle"
android:layout_alignLeft="#+id/rlSignInForm"
android:layout_alignRight="#+id/rlSignInForm"
android:layout_marginTop="180dp"
android:background="#drawable/rounded_rect_positive_selector"
android:gravity="center"
android:text="#string/SEND_PASSWORD"
android:textColor="#android:color/white"
android:textStyle="bold"
android:visibility="gone" />

Set android:layout_width="match_parent". This should solve your problem.

I don't think that's possible, but if you always want to collapse the appbar, regardless of the position that you choose, you could simply call this after every request for the scroll:
appBarLayout.setExpanded(true/false)
This will cause the app bar to collapse.
Further reading:
AppBarLayout.setExpanded(boolean)
Out of scope:
You should split your XML files into more layouts and use <include> tag, this will greatly improve readability of those files.

Bottom bar hides the scrollview content

Below code has a bottom bar with two buttons which is fixed and not scrollable.
Above bottom bar the layout is scrollable. But the bottom content in the ScrollView hides behind the bottom bar.
I tried changing the parent layout which was not fixing the issue.
I don't know where I am wrong. Any help would be really thankfull.

Remove whole of the first LinearLayout
Add the below line to your ScrollView
android:layout_above="#+id/bottom_bar"
This makes sure that your ScrollView ends before the bottom bar so theres no overlapping.

In your first LinearLayout add android:layout_above="#+id/bottom_bar"
this will help you
try this

It will keep the scrolling above your bottom bar.

Can't get to the bottom of the content with my scrollview

I have my xml file. It is a RelativeLayout with a ScrollView and inside the ScrollView I have LinearLayout and many more. The problem is that I can't reach the end of the view, as you can see it end with a "Sign Up" button... But my view is cut by the scroll and I can just see the middle of the button, the other middle is off screen.
So, any suggestions for how can I fix this? How can I work with the ScrollView so it wraps all of my content...

this size of screnn. I have others layouts files with edittexts and It happens
only in this layout.
