android - 在 Notification 的操作按钮上设置 onClickListener

Question

我正在向用户发送一个通知，它有两个操作按钮“接受”和“拒绝”。

一旦用户点击“接受”，我想检查几个条件然后相应地进行。我不希望用户只导航到 Intent 中指定的屏幕。

更新:在执行以下代码时，通知已到达，但在单击“接受”或“拒绝”按钮时，没有任何反应!

这是我正在做的:

        public class MyService extends Service {

        DatabaseReference firebaseDatabaseFollowers;
        boolean newRequestBool;
        NotificationCompat.Builder mBuilder;
        String pBy, ss;
        GeoFire geoFire;
        GeoQuery geoQuery;
        Query query;

        @Nullable
        @Override
        public IBinder onBind(Intent intent) {
            return null;
        }

        @Override
        public void onCreate() {
            super.onCreate();

            firebaseDatabase = FirebaseDatabase.getInstance().getReferenceFromUrl("https://***-***.firebaseio.com/");
            geoFire = new GeoFire(FirebaseDatabase.getInstance().getReferenceFromUrl("https://***-***.firebaseio.com/geofire"));
            query = firebaseDatabaseFollowers.child("users").child(MainActivity.uid).child("child");

            final SharedPreferences sharedPref2 = PreferenceManager.getDefaultSharedPreferences(this);
            newRequestBool = sharedPref2.getBoolean(SettingsActivity.KEY_PREF_NOTIF_NEW_REQUEST, true);

            ReactiveLocationProvider locationProvider = new ReactiveLocationProvider(getBaseContext());

                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // here to request the missing permissions, and then overriding

                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.
                return;
            }
            locationProvider.getLastKnownLocation()
                    .subscribe(new Action1<Location>() {

                            currentLngDouble = location.getLongitude();
                            geoQuery = geoFire.queryAtLocation(new GeoLocation(currentLatDouble, currentLngDouble), Double.parseDouble(MainActivity.radiusValue));

            // Because clicking the notification opens a new ("special") activity, there's
            // no need to create an artificial back stack.

                    PendingIntent.getActivity(
                            getBaseContext(),

            @Override

Log.d("BROADCAST", "Broadcast received");
            if (intent.getAction() != null && intent.getAction().equals(getString(R.string.broadcast_id))) {

                Intent intent1 = new Intent(MyService.this, MainActivity.class);
                startActivity(intent1);

                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        if (String.valueOf(difference).contains("-")) {
                             // do the logic
                        } else if (String.valueOf(difference).equals("0")){
                            // do the logic
                        } else if (!String.valueOf(differenceCurrentStartTime).contains("-")) {
                            // do the logic
                        } else if (!String.valueOf(difference).equals("0") && !String.valueOf(difference).contains("-") && String.valueOf(differenceCurrentStartTime).contains("-")) {
                            // do the logic

                        }
                    }
                }, 1000);

            }
}
        }

    }

这是AndroidManifest.xml:

<receiver android:name=".MyBroadcastReceiver">
        <intent-filter>
            <action android:name="com.abc.ccc.BROADCAST_EVENT">
            </action>
        </intent-filter>

    </receiver>

这是 strings.xml:

// define a Broadcast Intent Action in String resources
    <string name="broadcast_id">com.abc.ccc.BROADCAST_EVENT</string>

请告诉我。

Answer 1

您可以使用 BroadcastReceiver 来执行此操作。当用户点击“接受”按钮时，在 BroadcastReceiver 的 onReceive() 中处理其操作。

// for notification itself
Intent notificationIntent = (new Intent()).setAction(INTENT_ACTION_HERE);
PendingIntent notificationPendingIntent = PendingIntent
        .getBroadcast(context, NOTIFICATION_INTENT_REQUEST_ID, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

// for action button
Intent actionIntent = new Intent(this, YourBroadcastReceiver.class);
PendingIntent actionPendingIntent = PendingIntent
        .getBroadcast(context,  ACTION_INTENT_REQUEST_ID, actionIntent, PendingIntent.FLAG_UPDATE_CURRENT);

// execute onNotificationClick
mNotificationBuilder.setContentIntent(notificationPendingIntent);

// execute onButtonClick
mNotificationBuilder.addAction(R.drawable.button_icon, BUTTON_TEXT, actionPendingIntent);

我做了this repository at github更好地理解和实现这一点。
