I don't know the answer to your question, but here's what I'd try.
First, the simplest thing. I think you might be able to use the
Activity's setRequestedOrientation function and set it to whatever
orientation you want it to stay in. So when the ProgressDialog is
started:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
When it returns, assuming you want the device's default behavior:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)
I'm not sure if
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) will
block orientation changes after it is issued. It might just change the
orientation once, but the ActivityInfo parameters seem to suggest
otherwise.
If that doesn't do the trick, then I'd get more complex. First, set
the Activity's android:configChanges="orientation" in the
AndroidManifest.xml, then implement onConfigurationChanged in the
Activity's class. Something like:
void onConfigurationChanged(Configuration newConfig) {
if (!priorityDialogIsShowing) {
switch(newConfig.orientation) {
case Configuration.ORIENTATION_PORTRAIT:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
break;
case Configuration.ORIENTATION_PORTRAIT:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
break;
default:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
break;
}
}
}
Anyway, I'm not an expert, that's just what I would try.
