Why dont all my textviews update with 1 button clicks? Requires multiple clicks

Why dont all my textviews update with 1 button clicks? Requires multiple
clicks

I have a simple tablelayout with many textview. When the button is pressed
only a few are updated, but what happens is that, you need to press the
button mutiple times for all the textviews to get updated. Why dont they
all change on the first/only click?

String[] measurement;
