Question

我正在尝试使用以下代码在onCreate的服务中布局Inflate：

// ...
public void onCreate() {    
    telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    call = new PhoneCall();

    IntentFilter intentFilter = new IntentFilter(outgoingIntent);
    registerReceiver(callReceiver, intentFilter);

    final LayoutInflater myInflator = (LayoutInflater) ctext.getSystemService(Context.LAYOUT_INFLATER_SERVICE );        

    onPhoneStatelistener = new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {

// ...

这是我的日志猫：

我刚刚收到“Null Pointer”错误。有什么建议吗？

当我尝试让LayoutInflater投入使用时，我通常会这样做：

LayoutInflater inflater = LayoutInflater.from(Context);

希望这对你有用！
