android - 接听电话后正在播放媒体播放器？

Question

我正在使用此代码来收听电话的状态。当电话到达时，它会暂停媒体播放器，但一旦我接听电话，它就会从监听扬声器（而不是铃声）再次开始播放。我也尝试在这种情况下删除mediaPlayer.start()fromcase TelephonyManager.CALL_STATE_IDLE:它工作正常，但它不会再次启动（恢复）。有没有可用的标志来做到这一点？

 private final PhoneStateListener phoneListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
    try {
        switch (state) {
        case TelephonyManager.CALL_STATE_RINGING: 
            Toast.makeText(context, "Call is Coming",Toast.LENGTH_SHORT).show();
            mediaPlayer.pause();
        break;

        case TelephonyManager.CALL_STATE_OFFHOOK: 

        break;

        case TelephonyManager.CALL_STATE_IDLE: 
            mediaPlayer.start();

        break;

        default: 
        }
        } catch (Exception ex) {
            mediaPlayer.release();
        }
    }
};

}

或者有没有其他方法可以做到这一点？

尝试这个：

PhoneStateListener phoneStateListener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        if (state == TelephonyManager.CALL_STATE_RINGING) {
            //Incoming call: Pause music
        } else if(state == TelephonyManager.CALL_STATE_IDLE) {
            //Not in call: Play music
        } else if(state == TelephonyManager.CALL_STATE_OFFHOOK) {
            //A call is dialing, active or on hold
        }
        super.onCallStateChanged(state, incomingNumber);
    }
};
TelephonyManager mgr = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
if(mgr != null) {
    mgr.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}
