在来电时和当我打电话给某人时停止音乐

Question

嗨我想完全停止音乐，当有人打电话给我，如果我现在打电话给某人就像应用程序把音量调低，我仍然可以在背景中听很低但是我想停止音乐继续我现在的代码：

PhoneStateListener phoneStateListener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        if (state == TelephonyManager.CALL_STATE_RINGING) {
            wasPlayingBeforePhoneCall = radioService.isPlaying();
            radioService.stop();
        } else if (state == TelephonyManager.CALL_STATE_IDLE) {
            if (wasPlayingBeforePhoneCall) {
                radioService.play();
            }
        } else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
            // A call is dialing, active or on hold
            wasPlayingBeforePhoneCall = radioService.isPlaying();
            radioService.stop();
        }
        super.onCallStateChanged(state, incomingNumber);
    }
};

播放方法：

public void play() {
    if (hasConnectivity()) {
        if (getCurrentStationType().equals(TYPE_AAC)) {
            prepare();
        } else {
            if (isPrepared) {
                isRadioPlaying = true;
                mediaPlayer.start();
                System.out.println("RadioService: play");
                setStatus(STATUS_PLAYING);
                sendBroadcast(new Intent(MODE_PLAYING));
            } else {
                prepare();
            }
        }
    } else
        sendBroadcast(new Intent(MODE_STOPPED));

}

停止方法：

public void stop() {
    timeCounter = -1;
    resetMetadata();
    isPrepared = false;
    System.out.println("RadioService: stop");

    if (getCurrentStationType().equals(TYPE_AAC)) {
        if (isRadioPlaying) {
            isRadioPlaying = false;
            multiPlayer.stop();
        }
        // else
        // sendBroadcast(new Intent(MODE_STOPPED));
    } else {
        mediaPlayer.stop();
        mediaPlayer.reset();

        isRadioPlaying = false;
        setStatus(STATUS_STOPPED);
        sendBroadcast(new Intent(MODE_STOPPED));
    }
    // clearNotification();
}

我做错了什么？

谢谢。
