Android Prevent Box From Resizing

I am trying to make a four function calculator app. The two blank lines are the numbers involved in the calculations. The issue I have is with the 'result' box. Since I used relativelayout, the placement of everything is relative to the 'result' box. If I first calculate, say, 2+2 and 'result' is 4, it's ok. But if I do 5+5 and 'result' is now 10, a two digit number, everything shifts a little because 'result' has changed. Is there a way to let 'result' change size but keep everything else in place?

So you may not use Relative Layout. But can we use TableLayout?

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow
    android:layout_weight="2"
    android:layout_margin="20dp"
    android:layout_height="0dp"
    android:layout_width="match_parent">
    <EditText
        android:inputType="number"
        android:layout_gravity="bottom"
        android:id="@+id/num_1"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"/>
    <Space  android:layout_weight="1"
        android:layout_width="0dp"/>
    <EditText

</TableRow>
<TableRow
