Question

想知道如何在不使用Manifest文件的情况下创建SMS广播接收器。例如，这是我当前的清单文件行：

<receiver android:name="com.paradopolis.randomnotifications.SMSListener">
        <intent-filter>
          <action android:name="android.provider.Telephony.SMS_RECEIVED" />
       </intent-filter>
</receiver>

并且它工作正常，但我希望能够删除该行并在我的服务中注册我的广播接收器，如：

registerReceiver(new SMSListener() , [?????]);

但我找不到要使用的Intent过滤器，因为SMS_RECEIVED是Telephony包的一部分。所以问题是：那个意图过滤器是什么？

Answer 1

在您的java文件中创建IntentFilter，然后registerReceiver(Receiver, IntentFilter)

该操作将android.provider.Telephony.SMS_RECEIVED作为字符串。

IntentFilter i = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(new SMSListener() , i);

    mSmsReceiver = new SMSreceiver();
    IntentFilter filter = new IntentFilter();
    filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
    filter.addAction(SMS_RECEIVE_ACTION); // SMS
    filter.addAction(WAP_PUSH_RECEIVED_ACTION); // MMS
    this.registerReceiver(mSmsReceiver, filter);

    class SMSreceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (!getSMSBlockEnable()) {
            return;
        }

        if (TextUtils.equals(intent.getAction(), SMS_RECEIVE_ACTION)) {

            Bundle bundle = intent.getExtras();
            if (bundle == null) {
                return;
            }
            Object[] messages = (Object[])bundle.get("pdus");

            SmsMessage smsHeader = SmsMessage.createFromPdu((byte[])messages[0]);
            if (smsHeader != null) {
                mReceiveNumber = smsHeader.getOriginatingAddress();
                if(TextUtils.isEmpty(mReceiveNumber)) {
                    mReceiveNumber = INVALID_NUMBER;
                }
            }

           for (Object message : messages) {
                SmsMessage sms = SmsMessage.createFromPdu((byte[])message);
                  if (sms != null) {
                    body.append(sms.getDisplayMessageBody());
                  }
          }
          mReceiveBody = body.toString();
        }
    }
}
