[英]Android Status Bar Notifications - Opening the correct activity when selecting a notification
[英]Firebase notifications: activity doesn't launch when status bar notification is clicked
我目前遇到以下問題:
怎么了:
能否請你幫忙?
啟動器活動代碼:
if (getIntent().getExtras() != null) {
Bundle extras = getIntent().getExtras();
String title = (String) extras.get(Constants.TOPIC_KEY_TITLE);
String imageUrl = (String) extras.get(Constants.TOPIC_KEY_IMAGE_URL);
String url = (String) extras.get(Constants.TOPIC_KEY_URL);
String description = (String) extras.get(Constants.TOPIC_KEY_DESCRIPTION);
Long sentTime = (Long) extras.get(Constants.TOPIC_KEY_SENT_TIME);
if (Util.isStringsNotNull(description)) {
News news = new News();
news.setTitle(title);
news.setMessage(description);
news.setDescription(description);
news.setImageUrl(imageUrl);
news.setUrl(url);
news.setDate(sentTime);
news.save();
EventBus.getDefault().post(new OnNewsUpdatedEvent(news));
AppPreferences.incrementUnseenNewsCount(this);
}
}
String action = getIntent().getAction();
if (Util.isStringNotNull(action) && action.equals(ACTION_SEARCH)) {
startActivity(MainActivity.getIntentActionSearch(this));
} else {
startActivity(MainActivity.getIntent(this));
}
自定義FirebaseMessagingService代碼:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
LogUtil.log(BASIC_TAG, "onMessageReceived called!");
String description = null;
String imageUrl = null;
String url = null;
String title = null;
Map<String, String> dataMap = remoteMessage.getData();
if (dataMap != null && !dataMap.isEmpty()) {
description = dataMap.get(Constants.TOPIC_KEY_DESCRIPTION);
imageUrl = dataMap.get(Constants.TOPIC_KEY_IMAGE_URL);
url = dataMap.get(Constants.TOPIC_KEY_URL);
title = dataMap.get(Constants.TOPIC_KEY_TITLE);
}
if (Util.isStringNotNull(description)) {
RemoteMessage.Notification notification = remoteMessage.getNotification();
News news = new News();
news.setDate(remoteMessage.getSentTime());
news.setTitle(Util.isStringNotNull(title) ? title : notification.getTitle());
news.setMessage(notification.getBody());
news.setDescription(description);
news.setImageUrl(imageUrl);
news.setUrl(url);
news.save();
EventBus.getDefault().post(new OnNewsUpdatedEvent(news));
AppPreferences.incrementUnseenNewsCount(this);
}
}
我將假設您在活動的onCreate()方法中擁有啟動器活動代碼。 創建活動后,如果單擊另一個通知,則不會再次調用onCreate()。
更新用戶已經看到的活動需要做的是覆蓋顯示數據的活動的onNewIntent(Intent intent)方法,並在那里更新您的視圖。
