如何控制自己的Android应用的声音量
我想这个问题的答案一定是典型的。关键是，当您单击它们时，我有一些播放声音的按钮。我想控制声音卷。我如何控制声音卷？我正在使用以下代码：
private fun playSound() {
val sound = getSystemService(Context.AUDIO_SERVICE) as AudioManager
sound.playSoundEffect(AudioManager.FX_KEY_CLICK, 1f)
}
I imagine the answer to this question must be something quite typical. The point is that I have some buttons that play sounds when you click on them. I want to control the sound volume. How do I control the sound volume? I am using the following code:
private fun playSound() {
val sound = getSystemService(Context.AUDIO_SERVICE) as AudioManager
sound.playSoundEffect(AudioManager.FX_KEY_CLICK, 1f)
}

1是完整的卷吗？它没有提到任何其他值是最大常数或任何其他值。-1如果很方便的话，您的声音比当前的媒体音量设置更安静。您需要在0到1之间使用不同的值（我想！），看看您需要什么https://developer.android.com/reference/android/media/AudioManager#playSoundEffect(int,%20float)So you need to adjust that second parameter. I haven't used it, but it says that's a scalar so I'd imagine
1is full volume? It doesn't mention any other value as a max constant or anything.-1gives you a sound a little quieter than the current media volume setting, if that's convenient. You'll need to play around with different values between 0 and 1 (I assume!) and see what you need
