本文介绍了一种方法，即在接收到短信后，通过自定义通知的方式展示短信内容，并在用户点击通知时直接跳转至短信显示界面。具体实现包括创建短信通知、设置通知详情及点击事件响应。

本文主要实现接收到短信后，屏蔽系统Notification，自己建立所接短信的Notification，并且点击该通知，进入显示短信界面（自己设置）。

现将代码贴下

package com.lusgarden.texts.sms;

import com.lusgarden.texts.activity.R;
import com.lusgarden.texts.activity.SMSActivity;
mport android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SMSReceiver extends BroadcastReceiver {
private Context context;
public static int NOTIFICATION_ID = 21321;
private SmsMessage[] msg = null ;
private static final String strACT = "android.provider.Telephony.SMS_RECEIVED";
SmsManager smsMgr = SmsManager.getDefault();

public void onReceive(Context context, Intent intent) {
this.context = context;
if (intent.getAction().equals(strACT)) {
StringBuilder sb = new StringBuilder();
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
msg = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
for (SmsMessage currMsg : msg) {
sb.append("From:");
sb.append(currMsg.getDisplayOriginatingAddress());
sb.append("\nMessage:");
sb.append(currMsg.getDisplayMessageBody());
}
}
abortBroadcast();
Toast.makeText(context, sb.toString(), Toast.LENGTH_LONG).show();
/**
* call an intent to start the activity DisplayMessage with variable
* message data.
*/

/*
* Intent i = new Intent(context, SMSActivity.class);
* i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); i.putExtra("message",
* sb.toString()); context.startActivity(i);
*/
showNotification() ;
}
}

private void showNotification() {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"您有新短消息，请注意查收", System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, SMSActivity.class), 0);
notification.setLatestEventInfo(context, msg[0].getDisplayOriginatingAddress(),
msg[0].getDisplayMessageBody(), contentIntent);
notificationManager.notify(NOTIFICATION_ID, notification);
}
}
