Don't use findViewById (part 1 -- account setup)
Added two new functions:
- UiUtilities.getView()
is a fail-fast version of findViewById(). Crashes when there's no view
- setVisibilitySafe()
same as View.setVisibility, but doesn't crash even if a view doesn't exist
Let's try to avoid the use of findViewById(), and instead use getView(), *right
after* the layout is inflated, so that we'll always fail-fast if a layout
doesn't have a required view. (Rather than getting a NPE only when the view
is really accessed, which can be in a code path which is rarely executed--e.g.
only when there's a protocol error.)
Let's only use findViewById() only when we're sure no all the variants of a
layout have the view in question and leave a comment to make it clear it's on
purpose.
(UiUtilities has been moved from com.android.email to
com.android.email.activity)
