hope I can explain my situation correctly.. so i am working on a Recipes App with help of OpenUI5 for internal purposes at home.

I have a list of several receipts which all have a unique ID. So if I want to look at the details:

http://##URL##/myreceipts/#/detail/0

In the details section I would like to add a new list with the required things for this receipt.

So my JSON Model looks currently as follows:

I have a Activity that contains over 100 complex views (with images, text views etc). Showing up these views is to hard to do it without a Thread that loads the views asynchronously. So I tried to do it with an AsyncTask. I am not sure whether this is the correct way because the "hard staff" is something that HAS to be done in the UI Thread.

Now I've got the problem that the UI freezes though I used the onProgressUpdate for adding the views in the to parent view. I thought that this would result in single loading views that appear successive in the parent view. But this is not the case.

doInBackground fires all publishProgress calls and after that the main thread is blocked (activity frozen, loadbar does not rotate anymore). Is there a way to achieve what I wanted to have? I looked for solutions but alway ended up with ideas of using AsyncTask and no one had to do view-stuff as "hard staff". I am not using "get" in the AsyncTask what seems to be a problem with AsyncTask.

Here is my code for this. If you need any further information please tell me!

Is there any other way to solute this problem? Is my AsyncTask implementation not correct? I am looking for a way to load these complex views asyncronous to the parent view without blocking the main thread.

Thanks in advance!
