from the api document:

Causes the Runnable to be added to the message queue. The runnable will be run on the user interface thread. This method can be invoked from outside of the UI thread only when this View is attached to a window.

it look likes: if you want to update the view in another thread, you can simple using post method to update the view. Although the type is runnable, but it can't run in a separated thread, it will run in the ui thread just like invoke a normal method.
