How can I make the width of the TextView control containing the character "A" the same as the width of the text left-aligned and the control right-aligned?

I want the control "A" of the TextView that contains the characters to be the same width as the text left aligned and the control right aligned, so I have a TextView control that contains the characters "A" with max-width="150dp" and I have set it android:gravity="left"withandroid:layout_gravity="right"

I thought I could get the result AA.png, but actually the result is BB.png

I hope (AA.png)

Currently (BB.png)
