View.setVisible from a separate thread?

[mortefer]

Hi every1,
I've got a little problem here. I have an OpenGL thread that renders some of my stuff. On one point i need to display another view that has some buttons in it. The question is - how this can be done? because calling View.setVisible(View.VISIBLE) directly from OpenGL thread raises an exception (CalledFromWrongThreadException) that states that "Only the original thread that created a view hierarchy can touch it's views". Maybe i can set up some kind of listener for an activity that will periodically check for a flag and show other view if needed?

Thanx in advance

Okay looks like i'm gonna answer my own question
this is a synchronization issue that can be fixed using Handler object.
Main thread (Activity) creates a handler object and passes it to child processes. When needed, child processes post messages to the handler that are caught using handleMessage method of handler object (you have to subclass from Handler in order to implement that method) and there you can do what ever you want.

Actually you don't need a handler. To do some stuff on the Activities thread you should use Activity.runOnUiThread(Runnable). It is the same in use as your Handler solution (wich is the way to go for non Activity classes!).
