How to adjust horizontal views in layout

Question

I am trying to adjust the sizes of my textviews based on the size of the device. However it's partial adjustments. Let me show you what i mean:

The following picture depicts the desired effect. TextView B length determines the length of textview A, that is to say that part C is completely independent and is at the end with fixed size. If the textview A gets it's size reduced,then the end is elipsized. I have tried shifting from using LinearLayout with weights as well as RelativeLayout but haven't achieved the desired effect. Thoughts?

What i have tried:

<?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="100dp"
android:orientation="vertical">

<TextView
    android:id="@+id/a"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="@color/blue"
    android:textColor="@android:color/white"
    android:text="hi dear"
    />

<TextView
    android:id="@+id/b"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="@color/black"
    android:textColor="@android:color/white"
    android:text="hello world"
    android:layout_toRightOf="@+id/a"
    android:layout_toLeftOf="@+id/c"/>

<TextView
    android:id="@+id/c"
    android:layout_width="100dp"
    android:layout_height="match_parent"
    android:layout_alignParentRight="true"
    android:textColor="@android:color/white"

    android:background="@color/green"/>

</RelativeLayout>

As B Is Dependent On A,This Layout Will Work Fine For You. :)

Something like this?

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