如果已经通话并且第二个呼叫者正在呼叫，如何不触发 PhoneStateListener.CALL_STATE_RINGING
我正在编写一个应用程序，可以自动接听电话。问题是，如果我已经在通话中并且有人正在响铃，那么它不应该应答。 有办法实现吗？
根据文档，如果我使用 TelephonyManager 检查状态，它将是 CALL_STATE_RINGING 而不是 CALL_STATE_OFFTHEHOOK。
我是否必须添加一个在更改电话状态时设置为 true 的变量，以便我知道有正在进行的呼叫，或者是否有更好的解决方案？
谢谢！
/edit：我在没有 Modify_Phone_State 权限的情况下接听电话，所以这只是为了查明是否已经有通话正在进行。
I am programming an app, that automatically answers a call. The problem is, that it should not answer one if I am already in a call and someone is ringing.
Is there a way to achieve that?
According to the doc, if I check the status with TelephonyManager it would be CALL_STATE_RINGING and not CALL_STATE_OFFTHEHOOK.
Do I have to add a variable that is set true on a changing Telephone state so I know that there is an ongoing call or is there a better solution?
Thanks!
/edit: I answer the call without the permission Modify_Phone_State, so it is only about finding out if there is already a call ongoing.

跟踪呼叫状态是最好的方法，因为你的问题偏离了android标准。
你的问题没有官方答案，因为：
通过Android API，没有官方方法第三方应用程序提供商接听电话，因为
1：你必须使用未记录的 API。
2：请求 MODIFY_PHONE_STATE 权限仅适用于自 2.3 起的 root/系统签名应用程序
因此，如果您的问题存在有效（内置代码）工作答案，则它可能正式不适用于每个制造商/型号设备。

Tracking call state seams the best way, because your question is off the track of android standard.
There is no official answer to your question because :
By the Android API there is no official way for a third party application provider to answer to a phone call because
1 : you've to use undocumented API.
2 : request MODIFY_PHONE_STATE permission is only available for rooted/system signed application since 2.3
So if an efficient(build in code) working answer exist for your question, it may officially not working for every manufacturer/model devices.

好吧，显然没有办法解决这个问题，一旦状态变为
OFFTHEHOOK(true)，我就将布尔值存储在 SharedPreference 中。当状态更改为 IDLE 时，我将布尔值设置为 false。因此，这意味着，如果在有人已经呼叫时触发 RINGING，我会读出该变量为 true，然后放弃以下操作。

Okay, so as there is apparently no way to figure this out, I stored a Boolean in a SharedPreference as soon as the State goes to
OFFTHEHOOK(true).When the state changes to
IDLE, I set the Boolean to false. So this means, ifRINGINGis fired while someone is already calling, I read out that the variable is true, and then discard the following actions.For those who want more information on how to answer a call, have a look at the AutoAnswer Project
