Android: What's the difference between Activity.runOnUiThread and View.post?

android

Solution

There is no real difference, except that the `View.post` is helpful when you don't have a direct access to the activity.

In both cases, if not on UI thread, `Handler#post(Runnable)` will be called behind the scenes.

As CommonsWare mentioned in the comment, there is a difference between the two - when called on Ui thread, `Activity#runOnUiThread` will call the `run` method directly, while `View#post` will post the `runnable` on the queue (e.g. call the `Handler#post`)

The important point IMO is that both have the same goal, and for whoever use it, there should be no difference (and the implementation may change in the future).
