问题
is it ok in an activity's procedure to force the onResume event by calling this.OnResume() ? Or should I implement another procedure that's called by both OnResume and by the first member ?
回答1:
Implement another procedure that's called in your override of onResume(). The latter is not intended to be called by you, it's a convenience method that tidies up or readies the activity when its state changes to resume. A lot like onCreate() through to onDestroy().
回答2:
What @SK9 said, but also especially because you must call super.onResume() when you override the onResume method, so you're not in control what happens in the background (views getting refreshed, etc).
