(Android studio) ScrollView won't scroll all the way to the bottom

im trying to put a scroll view inside a frame layout. My scroll view is not scrolling all the way to bottom. this is my xml code. It is working when i give a padding to scroll view. but i need a better answer. because giving a padding will make a white margin below my application. Thank you!

Android ScrollView doesnt work

I'm trying to use scrollview in an app, but it doesn't work, the scroll bar doesn't appear and the buttons overlap, I'm using RelativeLayout to do this, I tried by other ways, but it doesn't work too.
Does someone know what I have to do?

You cannot use a RelativeLayout inside a ScrollView put the RelativeLayout inside a LinearLayout

Try this
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Linearlayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

android:layout_width="81dp"
android:layout_height="61dp"
android:layout_marginTop="20dp"
android:layout_marginLeft="20dp"
android:text="#string/Texto14"
android:id="#+id/buttonHomePerfilV"
android:textColor="#ffffff"
android:background="#333399"
android:layout_alignParentTop="true"

I think you need reformat your layout at all. If you will show image what you want to achieve and explain it's behavior, I will help to write more effeicient and clean xml.
You can make your layout like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Since you're using RelativeLayouts and aligning your views beneath one another, it's likely that the layout is extending beyond the bottom of the screen.
I encourage you to use a different combination of ViewGroups, for instance using a vertically oriented LinearLayout inside a ScrollView.

Can't resize a RelativeLayout inside a ScrollView to fill the whole screen

I am having a weird issue that I am not sure how to fix. I have a RelativeLayout inside a ScrollView and this scrollView has it's height set to fill_parent. So does the RelativeLayout. Still, the contents are not filling the entire screen and it's going only to the wrap_content of the last layout inside this RelativeLayout.
Here is my code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Anyone have ideas of how I can make the RelativeLayout2 to have the same height as the ScrollView, meaning, I want it to reach the bottom of the screen?
Thanks and regards,
Felipe

I have faced this problem before. Just Use android:fillViewport="true" in your scrollview and it will fill up the screen.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
