android 监听去电接通

Question

Android如何监听去电接通，是去电，不是来电。

Answer 1

去电接通和来电接通都是接通吧，应该都是一样的state，TelephonyManager.CALL_STATE_OFFHOOK

Answer 2

要在AndroidManifest.xml注册广播接收器:
<receiver android:name=".PhoneReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
<receiver android:name=".PhoneReceiver"> <intent-filter> <action android:name="android.intent.action.PHONE_STATE"/> <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> </intent-filter> </receiver>
还要添加权限:
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
