Android Service与Activity之间传值

Service：

  //在你需要传值的地方发送一个 
  /intent.putExtra("mesSum", data):这是需要传的参数
  //intent.action = "com.wimi.wsapp.framework.MessageService":这是Service所在位置
  val intent = Intent()  intent.putExtra("mesSum", data)  intent.action = "com.wimi.wsapp.framework.MessageService"  sendBroadcast(intent)

Activity：

    //注册广播接收器    var receiver = MyReceiver()    val filter = IntentFilter()    filter.addAction("com.wimi.wsapp.framework.MessageService")    activity.registerReceiver(receiver,filter)
inner class MyReceiver : BroadcastReceiver() {    override fun onReceive(context: Context, intent: Intent) {        val bundle = intent.extras        val count = bundle!!.getInt("mesSum")        if(count>0){            isViewActiveRunNow{                pointRed.visibility=View.VISIBLE            }        }else{            isViewActiveRunNow {                pointRed.visibility = View.GONE            }        }    }}
