android - Expand TextView with wrap_content until the neighbor view reaches the end of the parent

I need to achieve the following layout:

enter image description here

I have two TextViews in a relative layout: the green one is fixed text with wrap_content, the black one has dynamic text with wrap_content. The black text can change and become very long. I want the black TextView to expand with the text until the green view reaches the end of the parent. If that happens, the black TextView should stop expanding and ellipsize the end.

How can I achieve that?

What I tried:

 <RelativeLayout
    android:id="@+id/parent"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >


    <TextView
        android:id="@+id/leftTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:maxLines="1"
        android:layout_alignParentLeft="true"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/rightTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/leftTextView"
        android:textSize="18sp" />

</RelativeLayout>

But when the black text gets bigger and bigger it pushes the green one out of the view

You can archive this layout by TableLayout and shrinkColumns attribute.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <!-- Row 1 -->
    <TableLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:shrinkColumns="0">

        <TableRow
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_vertical">

            <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:padding="4dp"
                    android:maxLines="1"
                    android:ellipsize="end"
                    android:text="abcdefghijklmnopqrstuvwxyz"/>

            <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:padding="4dp"
                    android:maxLines="1"
                    android:ellipsize="none"
                    android:text="rightText"/>
        </TableRow>

    </TableLayout>


    <!-- Row 2 -->

        <TableRow
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_vertical">

            <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:padding="4dp"
                    android:maxLines="1"
                    android:ellipsize="end"
                    android:text="Longer Text view abcdefghijklmnopqrstuvwxyz"/>

            <TextView
                    android:layout_width="wrap_content"

                    android:ellipsize="none"
                    android:text="rightText"/>
        </TableRow>

    </TableLayout>

    <!-- Row 3 -->
    <TableLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:shrinkColumns="0">

        <TableRow
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"

            <TextView

        </TableRow>

    </TableLayout>

</LinearLayout>
