Question

我正在尝试在启动拨出电话后识别并转移到某个活动。我在Intent过滤器中使用了ACTION_NEW_OUTGOING_CALL。但是我怎么认识到呼叫是外向的。我为来电做了这个（如下所示），但我可以使用什么而不是EXTRA_STATE_RINGING。

public class OutgoingBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
        {
            Intent i = new Intent(context, OutgoingCallScreenDisplay.class);
            i.putExtras(intent);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}

Answer 1

public class OutgoingBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
           // If it is to call (outgoing)
           Intent i = new Intent(context, OutgoingCallScreenDisplay.class);
           i.putExtras(intent);
           i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           context.startActivity(i);
        }
    }
}

ACTION_NEW_OUTGOING_CALL 是Intent类中的常量声明，而不是TelephonyManager中的常量声明。当出现呼出呼叫时，系统使用此常量广播意图。如果您真的想使用TelephonyManager接听拨出电话，请执行以下操作：

TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);   
tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
PhoneStateListener listener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        // TODO Auto-generated method stub

        super.onCallStateChanged(state, incomingNumber);
        switch(state) {
            case TelephonyManager.CALL_STATE_IDLE:
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                if(incomingNumber==null) {
                    //outgoing call
                } else {
                    //incoming call
                }
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                if(incomingNumber==null) {
                    //outgoing call
                } else {
                    //incoming call
                }
                break;
        }
    }
};

检测外拨电话事件

<强> 1。创建OutgoingCallBroadcastReceiver

public class OutgoingCallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(OutgoingCallReceiver.class.getSimpleName(), intent.toString());
        Toast.makeText(context, "Outgoing call catched!", Toast.LENGTH_LONG).show();
        //TODO: Handle outgoing call event here
    }
}

<强> 2。在AndroidManifest.xml中注册OutgoingCallBroadcastReceiver

<receiver android:name=".OutgoingCallReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
    </intent-filter>
</receiver>

第3。在AndroidManifest.xml中添加权限

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
