问题
I want to know when an outgoing call is answered in my app. I am using a method called onCallStateChanged() from the PhoneStateListener class. I am looking at the Logcat when the outgoing call is answered to see which state it goes into (IDLE, OFFHOOK or Ringing). As per the documentation I would think it would go into the OFFHOOK but that is not the case.
Any ideas on how I can detect the outgoing call being answered?
回答1:
Phone state is Phonestate.Offhook as you are answering the call by offhooking the phone, it's obvious.
