Android:检测“请勿打扰"状态吗? [英] Android: Detect Do Not Disturb status?

问题描述

我只是想知道是否可以检查 Android设备(21 +)是否处于免打扰模式?我知道有AudioManager.RINGER_MODE_SILENT，但是我想知道这是否与这种情况有关，或者是否有更好的检查方法?

I was just wondering if there's a way to check if an Android device (21+) is in Do Not Disturb mode? I know there's AudioManager.RINGER_MODE_SILENT, but I was wondering if that pertains to this situation, or if there's a better way to check?

推荐答案

我为这篇文章带来了坏处，但是我只是在寻找解决同一问题的方法，并且像我一样走过了这篇文章，所以我离开了将来参考的解决方案.

I'm bringing the necro with this post, but was just searching for a solution to the same problem and came past this post as I did, so am leaving a solution for future ref.

我找不到执行此操作的官方"方法，但确实找到了可以将DnD状态返回为整数的值.该功能在内部称为"zen_mode"，因此您可以使用以下代码检查当前值:

I couldn't find an "official" way to do this, but did find a value that can return the DnD state as an integer. The feature is called "zen_mode" internally, so you can check the current value with the following code:

Global.getInt(getContentResolver(), "zen_mode")

那将返回:

• 0 -如果DnD为 off .
• 1 -如果DnD是 on -仅优先级
• 2 -如果DnD为 on -完全静音
• 3 -如果DnD已打开 -仅警报

• 0 - If DnD is off.
• 1 - If DnD is on - Priority Only
• 2 - If DnD is on - Total Silence
• 3 - If DnD is on - Alarms Only

当该设置仅是优先级时，它什么也不返回，但是您可以通过假设没有新闻= Priority Messages模式来弄清楚该状态.这肯定是一个错误，因为现在已经有一年了，它现在会返回一个值，就像其他状态一样.不知道何时修复它，但它现在可以按您期望的那样工作.

When the setting is priority only, it returns nothing, but you can figure out that state by assuming no news = Priority Messages mode. This must have been a bug, as now it's a year on, this now returns a value just like the other states. No idea when it was fixed, but it now works as you'd expect.

我也尝试过设置观察器，该观察器仅对某些状态转换有效，因此我认为定期轮询是最好的选择，直到可以使用官方"方式监听此状态变化为止.

I tried with a settings observer too, which works but only for certain state transitions, so I think polling periodically is the best bet, until an "official" way to listen for this state change becomes available.

我在此要点中包括了获取值的观察者和轮询方法.希望它能帮助/节省一些时间.

I've included both observer and polling methods of getting the value in this Gist. Hopefully it'll help/save someone else some time.

更新2017年3月15日:感谢 David Riha 的评论.添加了1 - Priority Only状态来回答，修改了要点以识别该状态并输出未知值，以便在其他设备或将来的更新决定返回其他值时进行记录.

Update 15th March 2017: Thanks to David Riha for the comment. Added 1 - Priority Only state to answer, revised the Gist to recognise that state, and to output unknown values to log in case any other devices or future updates decide to return a different value.
