Inflate a view in a background thread

Question

I have a very simple question:

Is or is it not possible to inflate a view (not add it to layout) in a background thread (ex: in the doInBack

With latest support lib you can use android.support.v4.view.AsyncLayoutInflater to inflate views asynchronously. Be careful though that it can fallback to inflating on UI thread if specific requirements are not met:

For a layout to be inflated asynchronously it needs to have a parent whose generateLayoutParams(AttributeSet) is thread-safe and all the Views being constructed as part of inflation must not create any Handlers or otherwise call myLooper(). If the layout that is trying to be inflated cannot be constructed asynchronously for whatever reason, AsyncLayoutInflater will automatically fall back to inflating on the UI thread.
