当我从主屏幕或 appDrawer 恢复应用程序时， onWindowFocusChanged() 被多次调用
以下是我从应用程序移至主屏幕然后从主屏幕移回应用程序时发生的控制台输出
HOME BUTTON PRESSED TO MINIMIZE THE APPLICATION: onWindowFocusChanged() -> hasFocus:false
: onWindowFocusChanged() -> hasFocus:true
: mySimpleSoundPlaybackMethods()
: onWindowFocusChanged() -> hasFocus:false
: onWindowFocusChanged() -> hasFocus:true
: mySoundPlaybackMethods()
the following is my console output of what happens when i move to the homescreen from the app and then move back to the app from the homescreen
HOME BUTTON PRESSED TO MINIMIZE THE APPLICATION
: onWindowFocusChanged() -> hasFocus:false
APPLICATION BUTTON PRESSED TO RETURN TO THE RUNNING APPLICATION
: onWindowFocusChanged() -> hasFocus:true
: mySimpleSoundPlaybackMethods()
Now the windowFocus has already become true... then why should the following occur again???
: onWindowFocusChanged() -> hasFocus:false
: onWindowFocusChanged() -> hasFocus:true
: mySoundPlaybackMethods()

我将进行一个完整的猜测......也许是因为当应用程序恢复时您所触摸的任何内容都具有焦点？ （再次，完全猜测）应用程序获得焦点，然后转移到您的触摸事件，然后返回到应用程序。
I'm going to throw a complete guess into the ring ... maybe because whatever you're touching has focus when the application resumes? (again, complete guess) App gets focus then transfers to your touch event then back to app.
