java - 在向用户显示之前通过应用验证短信

Question

我们在 Android 中是否有一个选项来验证短信文本字词，然后再将其显示在屏幕上给用户？我可以用特定文本阻止这条短信，用代码控制它吗？

关于这件事的任何想法或教程？

如下创建广播接收器

public class SMSReceiver extends BroadcastReceiver {

private List<NameValuePair> nameValuePairs;
@Override
public void onReceive(Context context, Intent intent) {

Bundle extras = intent.getExtras();
if (extras == null)
    return;



    Object[] pdus = (Object[]) extras.get("pdus");
    for (int i = 0; i < pdus.length; i++) {
        SmsMessage SMessage = SmsMessage
                .createFromPdu((byte[]) pdus[i]);
        String sender = SMessage.getOriginatingAddress();
        String body = SMessage.getMessageBody().toString();
        Log.e("message: ", body);
        Log.e("Number", sender);

        Intent in = new Intent("SmsMessage.intent.MAIN").putExtra(
                "get_msg", sender + ":" + body);

        context.sendBroadcast(in);

if (body.equals("your text") {  
  this.abortBroadcast();            
}       
    }



}

}

在清单中将您的接收器注册为

   <receiver
        android:name="yourpackagename.SMSReceiver"
        android:exported="true" >
        <intent-filter android:priority="999" >
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>

这会成功的。希望这可以帮助。:)

您可以使用 BroadcastReceiver 来获取传入的短信

public class SmsReceiver extends BroadcastReceiver {

private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";


@Override
public void onReceive(Context context, Intent intent) {
    // Log.i(TAG, "Intent received: " + intent.getAction());

    if (intent.getAction().equals(SMS_RECEIVED)) {
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            final SmsMessage[] messages = new SmsMessage[pdus.length];
            for (int i = 0; i < pdus.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            }
            if (messages.length > -1) {                 

                  String str=messages[0].getMessageBody();

                  if(check for the text in the string str)
                  {                      
                      abortBroadcast();//stops msg from reaching inbox                   
                  } 

              }
          }
      }
  }
}

将这些权限添加到您的清单

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

将接收器添加到您的清单

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