安卓intent接收短信

在Android应用开发中，Intent是用于启动活动、传递数据以及请求系统功能的核心组件。如果想让应用程序接收短信，你可以通过注册BroadcastReceiver来监听`ACTION_NEW_SMS`这个系统广播。以下是步骤：

1. **在AndroidManifest.xml中声明权限和BroadcastReceiver**:

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

2. **创建BroadcastReceiver类**:

   public class SMSReceiver extends BroadcastReceiver {
       @Override
       public void onReceive(Context context, Intent intent) {
           if (intent.getAction().equals(Telephony.Sms.Intents.SMS_RECEIVED_ACTION)) {
               Bundle bundle = intent.getExtras();
               SmsMessage[] messages = Telephony.Sms.Intents.getMessagesFromIntent(intent);
               // 处理接收到的短信数据
               for (SmsMessage message : messages) {
                   String smsBody = message.getMessageBody();
                   handleSMS(smsBody);
               }
           }
       }

       private void handleSMS(String smsBody) {
           // 这里编写处理接收到的短信的具体业务逻辑
       }
   }

3. **在需要的地方注册BroadcastReceiver**:

   registerReceiver(new SMSReceiver(), new IntentFilter(Telephony.Sms.Intents.SMS_RECEIVED_ACTION));

4. **记得在不需要接收短信时解绑BroadcastReceiver**:

   unregisterReceiver(SMSReceiver);
