Question

关于Kotlin中的某些代码，我遇到了一个小问题。我正在尝试在sendSMS函数中建立发送和传送的短信，然后在函数之后使用CURL发送结果，并每30秒调用一次函数以测试与其他手机的网络连接。

但是我有一个小问题：在onReceive操作期间，我的数据总是递归的。

经过大量研究，显然我需要使用一个unregisteredReceiver，但是如果使用它，我的应用程序将崩溃并且短信不会发送。

例如，在下面的代码中，如果我让unregisterReceiver进入我的函数，则我的应用程序将崩溃。

如果我删除了unregisterReceiver，它将正确加载我的函数，但是每隔30秒，它将添加一个“ testsent”：例如2分钟后，我将有4个testent，并且我的curl将执行4次。

您是否知道如何解决我的问题，以清理我的registerreceiver？

private fun sendSMS(phoneNumber: String, message: String, ID: String) {

   val SENT = "SMS_SENT"
   val DELIVERED = "SMS_DELIVERED"
   val sentPI = PendingIntent.getBroadcast(
       this, 0,
       Intent(SENT), 0
   )
   val deliveredPI = PendingIntent.getBroadcast(
       this, 0,
       Intent(DELIVERED), 0
   )
   //---when the SMS has been sent---
   val broadCastReceiver = object : BroadcastReceiver() {
       override fun onReceive(arg0: Context, arg1: Intent) {
           println("testsent")
           when (resultCode) {
               Activity.RESULT_OK -> Toast.makeText(
                   baseContext, "SMS sent",
                   Toast.LENGTH_SHORT
               ).show()

               SmsManager.RESULT_ERROR_NULL_PDU -> Toast.makeText(

                   Toast.LENGTH_SHORT
               ).show()
               SmsManager.RESULT_ERROR_RADIO_OFF -> Toast.makeText(
                   baseContext, "Radio off",
                   Toast.LENGTH_SHORT
               ).show()
           }
       }
   }
   registerReceiver(broadCastReceiver, IntentFilter(SENT))
   unregisterReceiver(broadCastReceiver)
   val url2 = URL("urltosendcUrl")
   var reqParam2 = URLEncoder.encode("sms sent", "UTF-8") + "=" + URLEncoder.encode(Activity.RESULT_OK.toString(), "UTF-8")
   reqParam2 += '&' + URLEncoder.encode("cdr_id", "UTF-8") + "=" + URLEncoder.encode(ID, "UTF-8")
   with(url2.openConnection() as HttpURLConnection) {
       requestMethod = "POST"  // optional default is GET
       val test = OutputStreamWriter(getOutputStream())
       test.write(reqParam2)
       test.flush()
       println("\nSent 'POST2' request to URL2 : $url2; Response Code : $responseCode")
   }
   //---when the SMS has been delivered---
   val broadCastReceiver2 = object : BroadcastReceiver() {
       override fun onReceive(arg0: Context, arg1: Intent) {
           println("testdelivered")
           when (resultCode) {
               Activity.RESULT_OK -> Toast.makeText(
                   baseContext, "SMS delivered",
                   Toast.LENGTH_SHORT
               ).show()
               Activity.RESULT_CANCELED -> Toast.makeText(
                   baseContext, "SMS not delivered",
                   Toast.LENGTH_SHORT
               ).show()
           }
       }
   }
   var reqParam3 = URLEncoder.encode("sms delivered", "UTF-8") + "=" + URLEncoder.encode(Activity.RESULT_OK.toString(), "UTF-8")
   reqParam3 += '&' + URLEncoder.encode("cdr_id", "UTF-8") + "=" + URLEncoder.encode(ID, "UTF-8")
   with(url2.openConnection() as HttpURLConnection) {
       requestMethod = "POST"  // optional default is GET
       val test = OutputStreamWriter(getOutputStream())
       test.write(reqParam3)
       test.flush()
       println("\nSent 'POST2' request to URL2 : $url2; Response Code : $responseCode")
   }
   registerReceiver(broadCastReceiver2, IntentFilter(DELIVERED))
   unregisterReceiver(broadCastReceiver2)
   val sms = SmsManager.getDefault()
   sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI)
   println("testdetest")

}

我只需要每30秒调用一次curl，而不是每增加1次调用就添加一次...
