Question

我目前有一个我想要使用的方法是OnReceive

public class IncomingSMSReceiver extends BroadcastReceiver {
private String senderNumber;

@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    SmsMessage[] msgs = null;

    String message = "";

    if (bundle != null) {
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];


        for (int i = 0; i < msgs.length; i++) {
            msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            message = msgs[i].getMessageBody();
            senderNumber = msgs[i].getOriginatingAddress();
        }
        senderNumber = msgs[0].getOriginatingAddress();

        Toast.makeText(context, message, Toast.LENGTH_LONG).show();
        sendMessage(senderNumber, "Thank you for sending me a message");
    }
}

我想在这个类中使用这个方法，但我不确定在调用方法时要放在方括号中。

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {


private GoogleMap mMap;
 IncomingSMSReceiver receiver = new IncomingSMSReceiver();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    receiver.onReceive();

有人可以帮我告诉我在onReceive（）括号中输入什么内容吗？

修改

我做了你说的并改变了我的代码，我也没有在ActivityMaps中调用onReceive。所以这是我的代码，它仍然不会回复＆＃34;测试＆＃34;短信，当＆＃34;更新＆＃34;短信发送给我。

public class IncomingSMSReceiver extends BroadcastReceiver {
private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";


@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(SMS_RECEIVED)) {
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            if (pdus.length == 0) {
                return;
            }
            SmsMessage[] messages = new SmsMessage[pdus.length];
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < pdus.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                sb.append(messages[i].getMessageBody());
            }
            String sender = messages[0].getOriginatingAddress();
            String message = sb.toString();
            String txtSMS="Testing";
            if (message.startsWith("UPDATE"))
            {

                Toast.makeText(context, message, Toast.LENGTH_SHORT).show();

                this.abortBroadcast();
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(sender, null, txtSMS, null, null);

            }

        }
    }
}

我的清单文件

receiver android:name=".IncomingSMSReceiver">
    <intent-filter android:priority="1000">
        <action android:name="android.intent.action.PHONE_STATE" />
        <action android:name="PACKAGE_NAME.android.action.broadcast"/>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
    </intent-filter>

尝试更新您的清单文件：

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

<!-- inside your application tag -->
<receiver android:name=".IncomingSMSReceiver">
    <intent-filter android:priority="2147483647" >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>
