Android layout with fixed button on bottom

I have the following xml which is supposed to be something similar to the following
The activity shows mostly ok, but i cant get the two down buttons to get fixed to the bottom of the screen without messing the top views.
I've tried to use a FrameLayout with two RelativeLayouts, alignment_bottom, an empty view with weight 1 between components and even still havent being able to accomplish my goal. Any help will be really appreciated, thank you in advance.

Change your layout file as below,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="match_parent"
android:layout_above="#+id/exit_group">

android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content">

Use Coordinator Layout as a parent layout. like this.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:card_view="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="false">
// your code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="horizontal">
<TextView
android:id="#+id/txt_contact_laksha_group"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="demo"
/>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>

View not visible in device but visible in XML

I am trying to build a layout with a right arrow and a vertical line with 2 textviews to right of it.
This layout will be used in a RecyclerView
This is the code that I am using,
<?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"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:clickable="true"
android:id="#+id/rootLayout"
>
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:layout_margin="#dimen/app_margin"
card_view:cardCornerRadius="4dp"
card_view:cardElevation="4dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
>
<View
android:layout_width="20dp"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:id="#+id/lineView"
android:layout_marginLeft="15dp"
android:background="#color/colorPrimary"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/name"
android:layout_toRightOf="#+id/lineView"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/type"
android:layout_toRightOf="#+id/lineView"
android:layout_below="#+id/name"
/>
<android.support.v7.widget.AppCompatImageView
android:layout_width="50dp"
android:layout_height="50dp"
app:srcCompat="#drawable/right_arrow"
android:layout_alignParentEnd="true"
android:layout_centerInParent="true"
android:id="#+id/right_arrow"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
This is the result of the above layout
The blue line is not visible when I run the output on my device but is visible in XML as shown
My Questions
How do I make it visible in my device ?
The blue line is very big I tried wrap_content but still did not work

You can simply align your lineView upto the height of text views. otherwise it will grow upto the device height. Refer this sample.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
app:cardBackgroundColor="#FFFFFF"
app:contentPadding="10dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<View
android:id="#+id/view"
android:layout_width="20dp"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/linearLayout"
android:layout_alignParentTop="true"
android:background="#color/colorPrimary" />
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toEndOf="#+id/view"
android:orientation="vertical"
android:padding="10dp">
<TextView
android:id="#+id/name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ABCD"
android:textSize="15sp" />
<TextView
android:id="#+id/value"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ABCD"
android:textSize="15sp" />
</LinearLayout>
<ImageView
android:id="#+id/img"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
app:srcCompat="#drawable/ic_keyboard_arrow_right_black_24px" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Screenshot of above example:

To fit the line according to content use this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white">
<View
android:layout_width="20dp"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:id="#+id/lineView"
android:layout_marginLeft="15dp"
android:background="#color/colorPrimary"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/name"
android:layout_toRightOf="#+id/lineView"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/type"
android:layout_toRightOf="#+id/lineView"
android:layout_below="#+id/name"
/>
<LinearLayout />

How to put a TextView at the end of my ScrollView?

I want to add a TextView at the bottom of my ScrollView, in which I can put the version number. So when a user first enters the screen, they don't see the Version Number. After they Scroll down, they can see the version number at the bottom of the screen. I tried all kinds of ways, doesn't work.
The layout is pretty nested.
This is the screenshot of the layout implementing the code below

Android Layout with Scrollview not at bottom - Fragment

What am I doing wrong that I can't get my "toolbar" to show up at the bottom of the screen (the free and post buttons)? I'm having to wrap this all inside a scroll view so that the keyboard will shift the view when displayed.
=======
UPDATE: Sorry I should have stated that the FREE and POST buttons must be at the bottom of the screen and maintain their size.
This is a FRAGMENT and the mainActivity has been set to android:windowSoftInputMode="adjustResize|adjustPan" however keyboard display is not scrolling the either.

Your toolbar is wrapped in a RelativeLayout which is wrapped in another RelativeLayout of which layout_height is set to wrap_content, here it is:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/red">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" <!-- here -->
android:background="#color/puregreen"
android:id="#+id/createTopView"
android:clickable="false">
Try changing this to match_parent and see if it works.

Why not use linearLayout as the child of scrollView? And set fillViewport property of the scrollView to true to stretch it's contents. Try this code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"

Centering empty view when ListView is empty

I'm learning how to develop Android application and am trying to add an image and a text centered on the screen if the ListView is empty. I've used the FrameLayout but it didn't work. I could use a margem Top, but this would cause a cut in the landscape mode. any idea?

thanks in advance!

ListView has a built in method for that. Try calling listView.setEmptyView(), and pass the view you created for this.

Mistakes...
First, I have not used "match_parent" in the height of the main layout.
And finally I have not used the FrameLayou with weight="1"
image and text is in the center :)
Now, it works like a charm
