推荐答案

看看BroadCastReceivers您必须实现并注册Reciever为 android.provider.Telephony.SMS_RECEIVED

Take a look at BroadCastReceivers you must implement and register a Reciever for android.provider.Telephony.SMS_RECEIVED

下面是一个code片段，让您阅读邮件送达。

Here is a code snippet that lets you read messages as they arrive.

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SMSReceiver extends BroadcastReceiver
{
    public void onReceive(Context context, Intent intent)
    {
        Bundle myBundle = intent.getExtras();
        SmsMessage [] messages = null;
        String strMessage = "";

        if (myBundle != null)
        {
            Object [] pdus = (Object[]) myBundle.get("pdus");
            messages = new SmsMessage[pdus.length];

            for (int i = 0; i < messages.length; i++)
            {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                strMessage += "SMS From: " + messages[i].getOriginatingAddress();
                strMessage += " : ";
                strMessage += messages[i].getMessageBody();
                strMessage += "\n";
            }

            Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();
        }
    }
}

在这里，你有什么要添加到您的Andr​​oidManifest.xml文件：

And here what you have to add to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.RECEIVE_SMS" />

<receiver android:name=".SMSReceiver">
    <intent-filter> 
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/> 
    </intent-filter> 
</receiver>
