Question

我正在使用此代码，以收听手机的状态。当呼叫到达时它会暂停媒体播放器，但是一旦我接听电话，它就会从收听扬声器（而不是振铃器）开始播放。我也尝试从mediaPlayer.start()移除case TelephonyManager.CALL_STATE_IDLE:，在这种情况下，它工作正常，但它不会再次启动（恢复）。有没有可用的旗帜？

 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();
        }
    }
};

}

或者还有其他办法吗？

试试这个：

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);
}

接听电话后，媒体播放器正在播放？
