Fix unexpected truncation again.

Unexpected truncation happens again after [1].
This is fixed by setting match_parent into the container LinearLayout.

For the unexpected truncation of Holo Theme is came from other but
related root cause. To calculate the window and container width,
need to add container padding in addition to the maximum width of
the text view. Otherwise the width of the container view will be
shrunk and the contents will be truncated. This only happens on
Holo Theme since the padding of the container is zero on Material
Theme.

I manually confirmed this CL doesn't revive following issues
