Android Relative Layout In TableRow followed by TableRow with Linear Layout

Question

I am currently working on an Android application to be run on Android 6. I am completely new to Android development but have a little bit of WPF experience so I thought the XML would be similar. The following is what I would like the view to look like:

This is the XML I currently have to solve this problem:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/activity_guimain"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:weightSum="2"
    tools:context="indoorpilot.indoorpilot.GUIMain">
    <TableRow>
        <!--android:layout_width="match_parent">-->
        <TextView
            android:id="@+id/textView"
            android:layout_weight="1"
            android:gravity="center_horizontal"
            android:text="Building Label"/>
    </TableRow>


    <TableRow>
        <RelativeLayout
            android:layout_weight="1">
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:srcCompat="@drawable/mclaurysecondfloor"
                android:id="@+id/imageView2"/>
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:srcCompat="@android:drawable/presence_online"
                android:="@+id/markerImage"/>

        </RelativeLayout>
    </TableRow>

    <TableRow>
        <LinearLayout
            android:layout_weight="1"
            style="?android:attr/buttonBarStyle">
            <Button
                style="?android:attr/borderlessButtonStyle"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="@string/contextual_info"
                android:onClick="ShowContextualInformation"/>
            <Button
                style="?android:attr/borderlessButtonStyle"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="@string/scan_button"
                android:onClick="SetRSSIDistanceValues"/>
        </LinearLayout>
    </TableRow>
</TableLayout>

Which is working fine on a large device (tablet) but it does not show properly in the Android Studio View Renderer OR on a phone of any sorts. The buttons are not shown as the TableRow containing the RelativeLayout ends up taking up the entire screen...

I've done this outside android studio, but may help you, if you need I can edit for you.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/activity_guimain"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:weightSum="2"
    tools:context="indoorpilot.indoorpilot.GUIMain">

    <TextView
        android:id="@+id/textView"
        android:gravity="center_horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Building Label"/>



        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/textView"
            android:layout_above="@+id/buttons_container"
            app:srcCompat="@drawable/mclaurysecondfloor"
            android:id="@+id/imageView2"/>

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/textView"
            app:srcCompat="@android:drawable/presence_online"
            android:id="@+id/markerImage"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_below="@+id/imageView2"
        android:layout_height="wrap_content"
        android:layout_orientation="horizontal"
        android:id="@+id/buttons_container"
        style="?android:attr/buttonBarStyle">
        <Button
            style="?android:attr/borderlessButtonStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/contextual_info"
            android:onClick="ShowContextualInformation"/>
        <Button
            style="?android:attr/borderlessButtonStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/scan_button"
            android:onClick="SetRSSIDistanceValues"/>
    </LinearLayout>

</RelativeLayout>

You don't need a TableLayout. What you need is a RelativeLayout that has one TextView at the top, two ImageViews below, and a LinearLayout containing the two buttons at the bottom of your view. You may need a ScrollView containing this RelativeLayout for smaller screen sizes.
