java - 是否有可能在空中接听 android 的来电？

Question

有谁知道 android 的“来电事件”？有资源还是我应该使用 TelephonyManager 自己制作？停用事件不适合我。

Answer 1

Android 设备上的电话位于 three states 之一:

CALL_STATE_IDLE (when it is not engaged in any calls), 
CALL_STATE_RINGING (when there is an incoming call and device is ringing), 
CALL_STATE_OFFHOOK (when the user answers the call)

甚至是 EXTRA_STATE 查找键 TelephonyManager#ACTION_PHONE_STATE_CHANGED action与 ACTION_PHONE_STATE_CHANGED 广播一起使用对应于这些状态如下:

EXTRA_STATE_IDLE  (Value used with EXTRA_STATE corresponding to CALL_STATE_IDLE)
EXTRA_STATE_OFFHOOK (Value used with EXTRA_STATE corresponding to CALL_STATE_OFFHOOK)
EXTRA_STATE_RINGING (Value used with EXTRA_STATE corresponding to CALL_STATE_RINGING)

因此，为了回答您的问题，目前 Android 中没有“空中来电”事件。
