I had asked one question about this error before (Android StackOverflowError in ViewGroup.resetResolvedTextDirection), however now I managed to reproduce the error in the emulator and narrowed down the specific place where this problem occurs.
When I'm starting my activity, I have an AsyncTask, which pulls the necessary data from my server and creates all views. Inside the run() method of the AsyncTask, I'm creating a custom view (and adding it to the main view of the activity - but that's not important now):
ListingView listing = new ListingView(MainActivity.this);
ListingView is my custom view class, which extends from LinearLayout. In the constructor of this custom view, I have this code:
public ListingView(Context context)
{
this.context = context;
...
LayoutInflater infl = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View top = infl.inflate(R.layout.listing, this, true);
this.addView(top);
...
LinearLayout lst = (LinearLayout)this.findViewById(R.id.LayoutListingTop);
tblVenues = new ListView(context);
tblVenues.setVisibility(VISIBLE);
tblVenues.setItemsCanFocus(true);
tblVenues.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(venueListener != null && venues.size() > 0) { venueListener.selected(venues.get(position)); }
}
});
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
lst.addView(tblVenues, lp); //this line causes the problem
...
}
In this custom view class, tblVenues is declared as
private ListView tblVenues;
And the XML that's being loaded is this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="@+id/LayoutListingTop"

This all works perfectly fine on Android form 1.6 up to 3.x, however on Ice Cream Sandwich (4.0) line
lst.addView(tblVenues, lp);
results in StackOverflowError:
java.lang.StackOverflowError

... this line repeats about 200 times or so ...
There's nothing else useful in the LogCat. The whole ListingView is not even added to the main activity view yet, because the error is thrown essentially from its constructor.
I'm a total loss as to what may be the problem. Any help will be greatly appreciated.
After banging my head against the wall for quite some time and trying all sorts of different approaches, I believe, this really is a bug in an android, which is exhibited when a View's visibility is explicitly set to VISIBLE but the view itself and the view's parent is not added to the main view.
I finally got around it by adding the ListView to XML and moving the code setVisibility(View.VISIBLE) to after the entire view is added to the main view (i.e. parent hierarchy can be traced from each child all the way to the end).
At least I'm not getting this error any more.
