不能停止在Android的播放声音的其他行为的MediaPlayer的 [英] Cant stop playing sound in other Activity with MediaPlayer in Android

问题描述

我想在我的Andr​​oid应用程序播放背景声音。我使用一个单独的类作为SoundManager类。而在我的第一个活动，我开始的声音，我想它通过其他2 activitys玩。而在我的第三类我希望它停下来，另一个声音应该发挥。
但是，拥有即时停止声音问题，不知道为什么。我猜它是与用我SoundManager类类的类上下文，即时通讯。

I'm trying to play a background sound in my Android application. I'm using a seperate class as a Soundmanager. And in my first activity, i start the sound and i want it to play through 2 other activitys. And in my third class i want it to stop and another sound should play. But im having a problem stopping that sound and don't know why. I guess it has something to do with that im using the class Context in my Soundmanager class.

有谁知道如何使声音停止了吗？我将我的链接类SoundManager类监守，它是唯一一个是相关的我猜。林pretty新的节目，所以请温柔。

Does anyone know how to make the sound stop? I'll link my Soundmanager class becuase that is the only one that is relevant i guess. Im pretty new to programming, so please be gentle.

推荐答案

请所有的方法和类变量 SoundManager类静态的（并通过在上下文为需要一个方法）。

Make all of your methods and class variables in SoundManager static (and pass in a Context for the methods that require one).

我会怀疑你也许在您的每一个活动，这将创建 SoundManager类 SoundManager类的新实例code>。使其静态访问将意味着所有的活动都修改相同的变量。

I would suspect that you are maybe creating a new instance of SoundManager in each of your Activities, which would create multiple instances of SoundManager. Making it statically accessible will mean all Activities are modifying the same variables.

另外要注意的，我不认为你必须有一个活动上下文，所以尝试通过通过在应用程序的上下文context.getApplicationContext（ ）。这将避免追平了的MediaPlayer 对象的任何具体活动。

Another note, I don't think you have to have an Activity Context, so try passing in your application's Context via context.getApplicationContext(). This will avoid tying the MediaPlayer object to any specific Activity.
