Hi folks,
I've been searching for a solution to this problem for the last
couple hours but haven't turned up a solution. I'm very new to using
Fragments, but building an app based around the ViewPager in the support
library. For the most part, I haven't had any problems, but I am running
into a situation where I'm using a DialogFragment in the hopes of
building a progress indicator while my app does some things in the
background. I have an indeterminate progress indicator running in my
DialogFragment, and I want to update one of two TextViews I have in the
dialog as it progresses. I'm sending updates from my background service
& thread via a Handler that is then to update the designated TextView.
The problem is, that TextView isn't updating. I thought it might be an
issue with the static field I assign the result of the findViewById() to
(thinking that it may not exist before the dialog is displayed), so I do
a check and secondary findViewById() prior to changing the text via
TextView.setText(). Unfortunately, it appears that the TextView field is
always null, and so the view isn't getting updated.
What am I failing to do? Do I need to do something with
FragmentTransaction or FragmentManager in order to update this TextView?
Thank you for your assistance!
Raymond
