        for (int i = 0; i < messages.length; i++) {
            messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            String sender = messages[i].getOriginatingAddress();
            String messageBody = messages[i].getMessageBody();

            // Add your logic here to check and intercept the sms
            if (sender.equals("1234567890") && messageBody.contains("keyword")) {
                abortBroadcast(); // Block the SMS
                Toast.makeText(context, "SMS from blocked sender intercepted", Toast.LENGTH_SHORT).show();
            } else {
                // Forward the SMS to default messaging app
            }
        }
    }
}

在AndroidManifest.xml中注册SmsReceiver接收器：

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

请注意，这段代码演示了如何拦截指定发送者和包含特定关键字的短信。您可以根据自己的需求对短信内容进行进一步的处理和拦截。在实际应用中，建议添加权限READ_SMS和RECEIVE_SMS。
