Wrap your both the concerned buttons inside a linearlayout and it will work. with horizontal orientation .
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right">
<Button
android:id="#+id/editPassword"
android:layout_width="205dp"

Please try the following code, I just changed the scroll view to be match_parent for width and height and the linear layout to be match_parent for width& wrap_content for height.
Please note that this view won't scroll till you run it on a small screen device.
and please change the images as you need.

How to move buttons to bottom of screen?

Before I recently updated Android Studio, I had the buttons aligned to the bottom of the screen. Whenever I try to use android:layout:_alignParentBottom inside of a relative layout that layout param apparently does not exist now.
The left is how it looked before and the right is how it looks now

Use RelativeLayout instead of ScrollView if you don't have a view hierarchy that can be scrolled.
A ScrollView is a FrameLayout, meaning you should place one child in
it containing the entire contents to scroll;

Note:
- To move the layout when keyboard comes up, add the following attribute to your activity inside AndroidManifest.xml file:
android:windowSoftInputMode="adjustResize"

you can layout like that:
RelativeLayout in overall
ScrollView for your contents Layout
(LinearLayout, RelativeLayout...) at the bottom button
<?xml version="1.0" encoding="utf-8"?>
