是否有可能关闭所有声音只是一个应用程序，并保存选择，直到应用程序的下一个开始？

Is it possible to turn off all sounds of just one app and to save the choice until the next start of the app?

所以，我必须在StartActivity和pressing此按钮切换按钮，应用程序的所有声音应该被取消，但其他应用程序的声音仍然应该工作。

So I have a ToggleButton at the StartActivity and by pressing this Button, all sounds of the app should be deactivated, but sounds of other apps should still be working.

我和preferences试了一下，使用共享preferences类，XML文件等，就像在我的书。但通过我意识到引进去，即preferences只是一种方式来保存数据永久的。 所以，我必须包括例如在拥有完善的每个按钮的if子句来检查，如果这样或那样的救preference声音开/关是真/假，然后激活/关闭声音？

I tried it with Preferences, using the SharedPreferences class, an xml file and so on, like in my book. But going through the introduction i realized, that the Preferences are just a way to save data permanent. So I would have to include for example on every Button with a sound an if-clause that checks if this or that saved preference for sound on/off is true/false and then activates/deactivates the sound?

我认为这可能是更容易？

I thought that it could be easier?

推荐答案

其实，如果你想在你的应用程序中禁用的声音 - 你可以不玩了。你可以存储标志每种声音要在共享preferences玩，你想播放声音，每次检查。这真的很容易！

Actually, if you want to disable a sound in your application - you can just don't play it. You can store the flags for each sound you want to play in the SharedPreferences and check it every time you want to play a sound. It's really easy!
