android - 我如何将参数与 registerReceiver 一起传递？

Question

我创建了一个应用程序，用于将来电号码发送到蓝牙工作正常。现在我想将管理员号码用户从活动传递给接收者。我该怎么做？我尝试了一些东西，但我的 apk 崩溃了......在添加了传递变量方法之后.. .如果管理员呼叫，我想发送 bt 信号...

   public void onResume() {
 super.onResume();

 registerReceiver(new IncomingCallReceiver(), new   intentFilter("android.intent.action.PHONE_STATE"));

//Intent intent = new Intent("android.intent.action.PHONE_STATE");
//intent.putExtra("admin_no",strAdmin); // change number here.
//sendBroadcast(intent);

wl.acquire();

}

public void onReceive(Context context, Intent intent) {
            Bundle bundle = intent.getExtras();

           // String admin2 = intent.getStringExtra("admin_no");

            if(null == bundle)
                    return;

            Log.i("IncomingCallReceiver",bundle.toString());

            String state = bundle.getString(TelephonyManager.EXTRA_STATE);

            Log.i("IncomingCallReceiver","State: "+ state);

            if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
            {
                    String phonenumber =  bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
            Log.i("IncomingCallReceiver","Incomng Number: " + phonenumber);

                    String info = "Detect call... \nIncoming number: " + phonenumber;

                    Toast.makeText(context, info, Toast.LENGTH_LONG).show();

                   if(info.indexOf(admin)>0){


                     //Toast.makeText(context, "Alarm service!",Toast.LENGTH_LONG).show();

                          //Intent service = new Intent(context, Btservice.class);

                         //context.startService(service);

                         //String msg = intent.getStringExtra("data");

                   try {
                         //DetectCallBt.sendDataBT(bat);
                        Activity2.sendDataBT("1");
                    } catch (IOException e) {
                         //TODO Auto-generated catch block
                        e.printStackTrace();
                    }
   }
