Onesignal通知显示在OneSignal仪表板上，但未在通知栏中显示（android） _通知栏

卧疾丰暇豫，翰墨时间作。这篇文章主要讲述Onesignal通知显示在OneSignal仪表板上，但未在通知栏中显示（android）相关的知识，希望能为你提供帮助。
对于发送通知我使用Onesignal.I在我的设备中收到通知但未在通知栏中显示。我也可以在Alert Dialog中获得通知并显示。但是当我想在通知栏中显示时，不显示任何内容
【Onesignal通知显示在OneSignal仪表板上，但未在通知栏中显示（android）】androidManifest.xml中

< application android:name=".MyApplication" android:allowBackup="true" android:icon="@mipmap/logo16" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> < activity android:name=".SplashActivity"> < intent-filter> < action android:name="android.intent.action.MAIN" /> < category android:name="android.intent.category.LAUNCHER" /> < /intent-filter> < /activity> < !-- Disbale opening of launcher Activity --> < meta-data android:name="com.onesignal.NotificationOpened.DEFAULT" android:value="https://www.songbingjia.com/android/DISABLE" /> < activity android:name=".MainActivity" android:screenOrientation="portrait" /> < service android:name=".MyNotificationExtenderService" android:exported="false"> < intent-filter> < action android:name="com.onesignal.NotificationExtender" /> < /intent-filter>

MyNotificationExtenderService

public class MyNotificationExtenderService extends NotificationExtenderService {@Override protected boolean onNotificationProcessing(OSNotificationReceivedResult receivedResult) { receivedResult.payload.lockScreenVisibility = Integer.parseInt("-1"); JSONObject data = https://www.songbingjia.com/android/receivedResult.payload.additionalData; OverrideSettings overrideSettings = new OverrideSettings(); overrideSettings.extender = new NotificationCompat.Extender() { @Override public NotificationCompat.Builder extend(NotificationCompat.Builder builder) { // Sets the background notification color to Green on Android 5.0+ devices. builder = builder.setVisibility(Integer.parseInt("-1")); builder = builder.setVibrate(new long[]{0L}); return builder.setColor(new BigInteger("800d2f66", 16).intValue()); } }; OSNotificationDisplayedResult displayedResult = displayNotification(overrideSettings); Log.d("OneSignalExample", "Notification displayed with id: " + displayedResult.androidNotificationId); return true; } }

我的应用程序

public class MyApplication extends Application {private static Context context; public static Context getContext() { return context; }@Override public void onCreate() { super.onCreate(); context = getApplicationContext(); //OneSignal.setLogLevel(OneSignal.LOG_LEVEL.DEBUG, OneSignal.LOG_LEVEL.DEBUG); //MyNotificationOpenedHandler : This will be called when a notification is tapped on. //MyNotificationReceivedHandler : This will be called when a notification is received while your app is running. OneSignal.startInit(this) .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification) .unsubscribeWhenNotificationsAreDisabled(true) .init(); } }

的build.gradle

dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.onesignal:OneSignal:[3.6.2, 3.99.99]' compile 'com.android.support:cardview-v7:21.+' compile 'com.android.support:appcompat-v7:25.3.1' compile 'com.android.support:recyclerview-v7:25.3.1' compile 'com.mcxiaoke.volley:library:1.0.19' compile 'com.squareup.picasso:picasso:2.5.2' compile 'com.android.support:design:25.3.1' compile 'com.android.support.constraint:constraint-layout:1.0.2' compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2' testCompile 'junit:junit:4.12' }

答案试试这样，它对我来说很好。
在你的Myplication类文件里面就像这样创建write。

OneSignal.startInit(this) .setNotificationOpenedHandler(new SSNotificationOpenedHandler()) .setAutoPromptLocation(true) .init();

现在创建SSNotificationOpenedHandler类文件和SSNotificationOpenedHandler中的代码，如下所示。

public class SSNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler { /** * Callback to implement in your app to handle when a notification is opened from the Android status bar or * a new one comes in while the app is running. * This method is located in this Application class as an example, you may have any class you wish implement NotificationOpenedHandler and define this method. * * @param messageThe message string the user seen/should see in the Android status bar. * @param additionalData The additionalData key value pair section you entered in on onesignal.com. * @param isActiveWas the app in the foreground when the notification was received. */ @Override public void notificationOpened(String message, JSONObject additionalData, boolean isActive) { String additionalMessage = ""; try { Intent in = new Intent(MyApplication.getInstance(), MainActivity.class); in.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK); if (additionalData != null ) { if (additionalData.has("link")) { Log.d("OneSignalExample additionalData.getString("link") : " + additionalData.getString("link")); in.setData(Uri.parse(additionalData.getString("link"))); } additionalMessage = message + " Full additionalData: " + additionalData.toString(); }Log.d("OneSignalExample" +additionalData + ",additionalData"); Log.d("OneSignalExample", "message: " + message + " additionalMessage: " + additionalMessage); ShopSmartApplication.getInstance().startActivity(in); } catch (Throwable t) { t.printStackTrace(); } } }

最后在您的清单文件中，在application标记内声明以下内容
