有没有办法在android 7上将铃声模式设置为静音
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.M) {
amanager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
}
setRingerMode 适用于 Android 6 及更低版本。 来自文档：
“从 N 开始，铃声模式调整将切换不 除非应用已被授予请勿打扰，否则不允许打扰 访问。”
有没有什么方法可以在不打开“请勿打扰访问设置”的情况下通过系统应用程序或在构建平台代码（例如此应用程序具有请勿打扰权限等时允许）来实现此目的？

这是我的要点，可以帮助您解决问题
我想使用 AudioManager 在静音模式和正常模式之间切换手机，但它不适用于 android N 及更高版本。 cmets中的更多详细信息。注意：我自己是初学者，所以这绝不是专家级代码。我之所以分享它，是因为我发现这方面的帮助很少。

在阅读了许多资源并测试了不同的方法后，我得出结论，在 Android Nougat 及更高版本上，通知管理器的请勿打扰模式以某种方式覆盖了与音频和通知相关的所有内容。
因此，如果手机处于“请勿打扰”模式，则您无法更改声音设置或进行任何违反“请勿打扰”模式的更改。因此，如果您想让手机重新进入振铃模式，您首先需要更改 Notification InterruptionFiler。更改后，您也可以更改音量设置。这也体现在，如果开启勿扰模式，Android 将不允许您更改手机的音量，即使使用物理音量按钮也是如此。
要使此代码正常工作，您还需要拥有以下两个权限。
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>
【讨论】：
在清单中添加此权限
< uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>
并使用此代码弹出通知政策访问盛大
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
&& !notificationManager.isNotificationPolicyAccessGranted()) {
Intent intent = new Intent(
android.provider.Settings
.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
startActivity(intent);
}
