Android 中的长通知标题在应用程序被终止时被裁剪

Question

我们正在推送来自内置 React JS 的 Web 应用程序的通知。通知标题有大约 95 个字符，在 phone 上收到时会被裁剪。我们如何像在 Inshorts 应用程序中那样包装标题？当应用程序位于前台时，我们没有任何问题。

这是我们用来推送通知的 React JS 代码：

message = {
            notification: {
              title:"Long title with 95 characters",                  
              seoLink:"google.co.in",               
               image: "abc.jpg",            
              content_available: 'true'
            },           
            data: { 
            title:"Long title with 95 characters",           
            body: "body msg",                         
            seoLink:"google.co.in",             
               image: "abc.jpg",                
            },
            to: fcmToken
          };

这是我们在 Android 中使用的代码 Native:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, channelId)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(image)
                .setContentText(title)
                .setAutoCancel(true)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(title))
                .setColor(context.getResources().getColor(R.color.colorPrimary))
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setColor(context.getResources().getColor(R.color.colorPrimary))
                .setVibrate(vibrate)
                .setLights(0xff00ff00, 300, 100)
                .setWhen(System.currentTimeMillis());

如果您需要自定义布局，可以将 NotificationCompat.DecoratedCustomViewStyle 应用于您的通知。

创建名为 notification_small.xml 的自定义 xml 文件：

<TextView
    android:layout_width="wrap_content"  //here for the wrap content for the title
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:text="@string/notification_title"
    android:id="@+id/notification_title"
    style="@style/TextAppearance.Compat.Notification.Title" />

然后像这样构建你的通知：

// Get the layouts to use in the custom notification
RemoteViews notificationLayout = new RemoteViews(getPackageName(), R.layout.notification_small);
RemoteViews notificationLayoutExpanded = new RemoteViews(getPackageName(), R.layout.notification_large);

// Apply the layouts to the notification
Notification customNotification = new NotificationCompat.Builder(context, CHANNEL_ID)
        .setSmallIcon(R.drawable.notification_icon)
        .setStyle(new NotificationCompat.DecoratedCustomViewStyle())
        .setCustomContentView(notificationLayout) 
        .setCustomBigContentView(notificationLayoutExpanded)
        .build();
