c# - 用MonoDroid接收短信

编辑:现在已解决-在这里发布解决方案，以防将来有人需要它或任何人都可以提出一种更好的方法来解决此问题。我从 list 中删除了 Intent 内容，并在SmsReceiver类中设置了BroadcastReceiver。现在可以使用了。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.Util;
using Android.Telephony;

namespace dummyAndroid
{
    [BroadcastReceiver(Enabled = true, Label = "SMS Receiver")]
    [IntentFilter(new string[] { "android.provider.Telephony.SMS_RECEIVED" })]
    public class SmsReceiver : Android.Content.BroadcastReceiver
    {
        public static readonly string INTENT_ACTION = "android.provider.Telephony.SMS_RECEIVED";

        public override void OnReceive(Context context, Intent intent)
        {
            if (intent.Action == INTENT_ACTION)
            {
                StringBuilder buffer = new StringBuilder();
                Bundle bundle = intent.Extras;

                if (bundle != null)
                {
                    Java.Lang.Object[] pdus = (Java.Lang.Object[])bundle.Get("pdus");

                    SmsMessage[] msgs;
                    msgs = new SmsMessage[pdus.Length];

                    for (int i = 0; i < msgs.Length; i++)
                    {
                        msgs[i] = SmsMessage.CreateFromPdu((byte[])pdus[i]);

                        Log.Info("SmsReceiver", "SMS Received from: " + msgs[i].OriginatingAddress);
                        Log.Info("SmsReceiver", "SMS Data: " + msgs[i].MessageBody.ToString());
                    }

                    Log.Info("SmsReceiver", "SMS Received");
                }
            }
        }
    }
}

我正在编写一个用于发送/接收SMS消息的应用程序，并且可以通过SMS Mananger发送工作。

我现在正尝试在Android版Mono中接收SMS，并且是Android开发的新手，所以可能做错了!

我在 list 中添加了以下内容

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto" package="com.me.dummyAndroid" android:versionCode="1" android:versionName="1">
  <uses-sdk android:targetSdkVersion="8" />
  <application
        android:label="meAndroidSMS"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
    <receiver android:name=".SmsReceiver">
      <intent-filter>
        <action android:name=
                    "android.provider.Telephony.SMS_RECEIVED" />
      </intent-filter>
    </receiver>
  </application>
  <uses-permission android:name="android.permission.SEND_SMS" />
  <uses-permission android:name="android.permission.RECEIVE_SMS" />
  <uses-permission android:name="android.permission.READ_SMS" />
</manifest>

然后，我创建了一个名为SmsReceiver.cs的新类，已在其中添加了onReceive函数，但在 Intent 中似乎没有getExtras函数，根据我阅读的在线教程(http://www.techques.com/question/1-3542320/IPhone-Android-SMS-intercept-and-redirection-to-an-application)。

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



        }
    }
}

我很肯定我对Android和MonoDroid有点过头了，但是也许有人可以为我指出正确的方向!

最佳答案

我在这里有一些有效的代码(我不记得源代码，但是我认为是与Xamarin关联的人编写了此示例)，在收到SMS时显示Toast。

using System.Text;

using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Util;
using Android.Widget;
using Android.Telephony;
using Environment = System.Environment;

namespace MonoDroid.SMSFun
{
    [BroadcastReceiver(Enabled = true, Label = "SMS Receiver")]
    [IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" })]
    public class SMSBroadcastReceiver : BroadcastReceiver
    {
        private const string Tag = "SMSBroadcastReceiver";
        private const string IntentAction = "android.provider.Telephony.SMS_RECEIVED";

        public override void OnReceive(Context context, Intent intent)
        {
            Log.Info(Tag, "Intent received: " + intent.Action);

            if (intent.Action != IntentAction) return;

            var bundle = intent.Extras;

            if (bundle == null) return;

            var pdus = bundle.Get("pdus");
            var castedPdus = JNIEnv.GetArray<Java.Lang.Object>(pdus.Handle);

            var msgs = new SmsMessage[castedPdus.Length];

            var sb = new StringBuilder();

            for (var i = 0; i < msgs.Length; i++)
            {
                var bytes = new byte[JNIEnv.GetArrayLength(castedPdus[i].Handle)];
                JNIEnv.CopyArray(castedPdus[i].Handle, bytes);

                msgs[i] = SmsMessage.CreateFromPdu(bytes);

                sb.Append(string.Format("SMS From: {0}{1}Body: {2}{1}", msgs[i].OriginatingAddress,
                                        Environment.NewLine, msgs[i].MessageBody));
            }

            Toast.MakeText(context, sb.ToString(), ToastLength.Long).Show();
        }
    }
}

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="internalOnly" package="monodroid.smsfun" android:versionCode="1" android:versionName="1.0">
  <uses-sdk android:targetSdkVersion="8" />
  <application android:label="SMSFun">
  </application>
  <uses-permission android:name="android.permission.RECEIVE_SMS" />
