I have an activity that shows a scrollview with a lot of linearlayouts with
a lot of imageviews and textviews.
This activity must show two columns in my scrollview if the orientation is
landscape, and it must show one column in my scrollview if the orientation
is portrait.
It works fine. I have this code on the onCreate method:
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
sw=dm.widthPixels;
sh=dm.heightPixels;
if (sw>sh)
portrait=false;
with that code i can check if the screenorientation is portrait or
landscape, and then, generate one or two columns in my scrollview. So, each
time the user changes the screen orientation, the oncreate get's called
again and check wich is the current screen orientation.
*As i said, it works fine, but here comes the problem:*
This activity shows some buttons for download content from internet using a
AsyncTask that shows a horizontal ProgressBar. If i change the orientation
while i'm downloading the content from internet and showing the
progressBar, then i get a exception like this:
04-11 14:29:22.655: INFO/WindowManager(1086): Setting rotation to 0,

android.view.ViewRoot.<init>(ViewRoot.java:247)
Then, i suposed that i must lock the screen orientation changes when the
user is downloading content and showing the progressbar dialog, and i tryed
it locking and unlocking it with this:
((Activity)
context).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
((Activity)
context).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
IT WORK'S FINE IF I'M IN PORTRAIT MODE and after i start downloading
something i try to change to landscape, it blocks the change and works
finde. *But if i'm in landscape mode and i press the button for download
the content from internet and i start the progressbar dialog, then i get
this exception, and no need to try to change the orientation to portrait
mode, i get the exception instantly:*
