Android to the bottom of the screen there are three key
Return key, home button, menu (? Don't know right)

When users click on the menu, how to respond to this event,
Found that high version (8.0) in the android, onkeyDown, dispatchKeyEvent can capture this event,

OnPause, onStop events such as though will be set out, but when the images and jump can also be triggered, cannot and press the menu button to separate zones,


Brainstorming, don't know you have what good method,

Yes, the return key on the left, middle home button can be detected, but on the right side of the square of the menu (? Is it called this name), press events don't know how to monitor,
Do you have way?

May be related to the machine?
Search on the net a lot of articles, found that very few people have the requirement of the detector the three buttons, few people ask this question, and seldom related articles,

CodePudding user response:

This is a virtual buttons, do you want to monitor outside the APP? My train of thought is the background service long term job, then there should be a way to listen to the three virtual buttons, but also related to hide the Settings of the kind of virtual buttons, don't remember how to write, but there are ways
