来电无振铃事件

Question

我不知道哪里有问题。监听器没有捕捉到onRinging事件（所以我可以决定是接受还是拒绝传入呼叫）。清单上是这样的：

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

在主活动onCreate中是这样的：

IntentFilter filter = new IntentFilter();
filter.addAction("android.SipDemo.INCOMING_CALL");
callReceiver = new IncomingCallReceiver();
this.registerReceiver(callReceiver, filter);
...
SipManager manager = SipManager.newInstance(this);
Intent i = new Intent();
i.setAction("android.SipDemo.INCOMING_CALL");
PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, Intent.FILL_IN_DATA);
manager.open(me, pi, null);

在BroadcastReceiver类中是这样的：

public void onReceive(Context context, Intent intent) {
SipAudioCall incomingCall = null;
try {
SipAudioCall.Listener listener = new SipAudioCall.Listener() {
...
@Override
public void onCallEnded(SipAudioCall call) {
// TODO Auto-generated method stub
super.onCallEnded(call);
}
@Override
public void onRinging(SipAudioCall call, SipProfile caller) {
try {
call.answerCall(30);
call.startAudio();
call.setSpeakerMode(true);
if(call.isMuted()) {
call.toggleMute();
}
} catch (Exception e) {
e.printStackTrace();
}
}
};
WalkieTalkieActivity wtActivity = (WalkieTalkieActivity) context;
incomingCall = wtActivity.manager.takeAudioCall(intent, listener);
wtActivity.call = incomingCall;
...

我收到了CallEnd事件和onChanged（在我结束呼叫后），但我没有收到onRinging事件。什么可能是问题？Thnx

编辑：我改变了一切。我把新的意图过滤器这样的接收器（粗体）：

<receiver android:name=".IncomingCallReceiver" android:label="Call Receiver">
    **<intent-filter>  
        <action android:name="android.intent.action.PHONE_STATE" />  
    </intent-filter>**  
</receiver>

我更改了BroadcastReceiver继承类，如下所示（粗体）：

@Override
public void onReceive(Context context, Intent intent) {
    try {
        **PhoneStateListener phoneListener=new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
        // TODO Auto-generated method stub
        Log.d("DEBUG", "Phone listener....");
        String stateString = "N/A";
        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
        stateString = "Idle";
        break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
        stateString = "Off Hook";
        break;
        case TelephonyManager.CALL_STATE_RINGING:
        stateString = "Ringing";
        break;
    }
}
};**
WalkieTalkieActivity wtActivity = (WalkieTalkieActivity) context;
SipSession ses=wtActivity.manager.getSessionFor(intent);
**TelephonyManager telephony = (TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE);  
telephony.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);**
...

现在我只有IDLE状态，但仍然没有铃声。

Answer 1

SipAudioCall类的源代码中存在错误。

解决这个问题：

incomingCall = wtActivity.manager.takeAudioCall(intent, null);
incomingCall.setListener(listener, true);

Answer 2

我在sip演示中实现了接受或拒绝传入呼叫的相同场景。使用Accept和Reject两个按钮创建自己的Activity（IncomingGui.java）。在BroadcastReciever类中，在传入调用事件上调用您的Activity（IncomingGui.java）。

        WalkieTalkieActivity wtActivity = (WalkieTalkieActivity) context;
        incomingCall = wtActivity.manager.takeAudioCall(intent, listener);
        showIncomingCallGui(intent, context); 
        wtActivity.call = incomingCall;

然后在BroadcastReciever类中定义以下方法

    public void showIncomingCallGui(Intent intent,Context context) {
       Intent incomingCall=new Intent(context,IncomingCallGui.class);
       context.startActivity(incomingCall);
    }
public static void answerIncomingCall(){
    try {
            incomingCall.answerCall(30);
            incomingCall.startAudio();
            incomingCall.setSpeakerMode(true);
                if (incomingCall.isMuted()) {
                incomingCall.toggleMute();
            }
    }
    catch(Exception e){
        System.out.println(e.toString());
    }
}
public static void rejectIncomingCall(){
    try {
            if (incomingCall !=null) {
                incomingCall.endCall();
                incomingCall.close();
            }
    }
            catch(Exception e){
        System.out.println(e.toString());
    }

然后在IncomingGui.java中，在"Accept"one_answers"Reject"按钮后面定义以下方法。现在，在来电中，您将有自己的来电活动来接受或拒绝来电。

    public void onCallAcceptButton(View view){
    IncomingCallReceiver.answerIncomingCall();
}
    public void onCallRejectButton(View view){
    IncomingCallReceiver.rejectIncomingCall();
    this.finish();
}
