在我的 Android 应用程序中,我想在 ios 等应用程序图标中显示推送通知徽章计数。

如何在应用程序图标中显示徽章计数?

Android 没有此特定功能。

另一种方法可能是有一个显示数字的通知,但应用程序图标本身在正常情况下无法使用。

如果你真的想打破设计准则,你可以制作一个看起来像你的应用程序图标的小部件,并且小部件可以更好地控制它的绘制方式。已经发布了一些应用程序来为 Gmail、谷歌语音、标准消息应用程序执行此操作,以及电话应用程序的未接来电,它们伪装成常规应用程序图标,因此这是可能的。我真的不推荐这种方法,但它是可用的。

1. 使用 ShortcutBadger 库进行徽章计数

        dependencies {
            compile 'me.leolin:ShortcutBadger:1.1.4@aar'
        }

2.

       public class MyFirebaseMessagingService extends FirebaseMessagingService {

            private static final String TAG = "MyFirebaseMsgService";

            Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

            @Override
            public void onMessageReceived(RemoteMessage remoteMessage) {

                // Check if message contains a data payload.
                if (remoteMessage.getData().size() > 0) {
                    Log.d(TAG, "1. remoteMessage.getData().size() > 0");
                    Log.d(TAG, "Message data payload: " + remoteMessage.getData()); // {mobile=9458074124, name=Arvind}
                    Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
                    Log.d(TAG, "Message getTitle: " + remoteMessage.getNotification().getTitle());
                    Map<String, String> notificationData1 = remoteMessage.getData();

                    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

                    Log.d(TAG, sharedPreferences.getString("userid", "") + ".....id"+notificationData1.get("action"));

                    try {

                        if (notificationData1.get("actionID").equalsIgnoreCase(sharedPreferences.getString("userid", ""))) {

                        } else {
                            showNotificationForEvent(remoteMessage);
                            // }

                        }


                    }catch (Exception e)
                    {
                        e.printStackTrace();
                    }

                }

            }

            // Show Notification for Attend,Like,Comment,Rate

            private void showNotificationForEvent(RemoteMessage remoteMessage) {

                        .setSound(defaultSoundUri)
