我是 Android 开发的新手，只是想创建一个程序，如果我收到一条短信，它将显示一个 Toast ......这是到目前为止的代码

SMSReceiveActivity.java

package sms.receive.sample;
import android.content.*;
import android.os.Bundle;
import android.telephony.*;
import android.util.Log;
import android.widget.Toast;

public class SMSReceiveActivity extends BroadcastReceiver {

private static final String TAG = "Message recieved";

@Override
public void onReceive(Context context, Intent intent) {   

 Bundle pudsBundle = intent.getExtras();
 Object[] pdus = (Object[]) pudsBundle.get("pdus");
 SmsMessage messages =SmsMessage.createFromPdu((byte[]) pdus[0]);    
 Log.i(TAG,  messages.getMessageBody());
 Toast.makeText(context, "SMS Received : "+messages.getMessageBody(),
 Toast.LENGTH_LONG).show();
}
  }

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="sms.receive.sample"
android:versionCode="1"
android:versionName="1.0" >    
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_SMS" /> 
<application icon="@drawable/ic_launcher" label="@string/app_name">
<receiver 
     android:name=".SMSReceiveActivity" 
     android:exported="true" 
     android:enabled="true">
     <intent-filter android:priority="999">
         <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
     </intent-filter>
</receiver>
</application>

当我向 AVD 发送（telnet）短信时，我会在抽屉中收到通知，但不会收到 Toast。我也试过我的手机，我也得到了同样的结果......非常感谢任何帮助。
