此例項實現功能為通過接收廣播讀取簡訊

實現很簡單，但使用到了廣播接受者，以免遺忘在此記錄：

程式碼

• AndriodMainfest檔案

申明許可權

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

配置廣播

        <receiver android:name="activity.SMSBroadcastReceiver">
            <intent-filter android:priority
 
="999">  
               <action android:name="android.provider.Telephony.SMS_RECEIVED" />  
           </intent-filter>
        </receiver>

• BroadcastReceiver檔案

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

public class SMSBroadcastReceiver extends BroadcastReceiver{
    //指定動作的名稱
    public static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";  

    @Override  
    public void onReceive(Context context, Intent intent) {  
        if (ACTION.equals(intent.getAction())) {
            //根據接收到的意圖物件獲取簡訊
 

            SmsMessage[] msgs = getMessageFromIntent(intent);
            //提取簡訊內容  
            StringBuilder sBuilder = new StringBuilder();  
            if (msgs != null && msgs.length > 0 ) {  
                for (SmsMessage msg : msgs) {  
                    sBuilder.append("接收到了簡訊：\n發件人是：");  
                    sBuilder.append(msg.getDisplayOriginatingAddress());  
                    sBuilder.append("\n------簡訊內容-------\n");
                    sBuilder.append(msg.getDisplayMessageBody()); 
                }  
            }

            System.out.println(sBuilder.toString());  
        }       
    }  

    //從意圖獲取簡訊物件的具體方法
    public static SmsMessage[] getMessageFromIntent(Intent intent) {  
        SmsMessage retmeMessage[] = null;  
        Bundle bundle = intent.getExtras();  
        Object pdus[] = (Object[]) bundle.get("pdus");  
        retmeMessage = new SmsMessage[pdus.length];  
        for (int i = 0; i < pdus.length; i++) {  
            byte[] bytedata = (byte[]) pdus[i];  
            retmeMessage[i]  = SmsMessage.createFromPdu(bytedata);  
        }  
        return retmeMessage;  
    }
}
