Question

在我的Android应用中，我会在用户开始上传文件和文件上传完成时提供通知。上传开始时，导航栏中会显示“正在上传”消息。上传完成后，我希望导航栏中的“上传完成”消息闪烁，但消息永远不会出现在导航栏中。但是，展开“通知”抽屉时，会显示正确的消息。

如何在导航栏中将内容标题设为Flash？

NotificationManager mNotificationManager =
                        (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                Constant.currentlyUploading.decrementAndGet();
                Constant.totalUploadedImages.incrementAndGet();
                if(Constant.currentlyUploading.get()>0){
                    String files_count;
                    if(Constant.currentlyUploading.get() ==1){
                        files_count = "file";
                    }else{
                        files_count = "files";
                    }
                    Builder uploadBuilder = new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.logo)
                    .setContentTitle("Uploading")
                    .setContentText(Constant.currentlyUploading.get()+ " " + files_count +  " uploading");
                    Notification uploadNotif = uploadBuilder.build();
                    mNotificationManager.notify(Constant.NOTIFICATION_UPLOADING_ID, uploadNotif);
                }else{
                    // cancel uploading notification
                    CancelNotification(this.context, Constant.NOTIFICATION_UPLOADING_ID);

                    String uploaded_count;
                    if(Constant.totalUploadedImages.get()>1){
                        uploaded_count = "files";
                    }else{
                        uploaded_count = "file";
                    }
                    Builder uploadedBuilder = new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.logo)
                    .setContentTitle("Upload complete")
                    .setContentText(Constant.totalUploadedImages.get()+" " + uploaded_count + " uploaded")
                    .setAutoCancel(true);
                    Notification uploadNotif = uploadedBuilder.build();
                    mNotificationManager.notify(Constant.NOTIFICATION_UPLOADED_ID, uploadNotif);    
                    Constant.totalUploadedImages.getAndSet(0);      

                }
                //Removing one from the step's image upload counter
                uploadStep.decTotalUploading();
                if(stepAdapter!=null){
                    stepAdapter.notifyDataSetChanged();
                }

                //Removing the path from the list of currently uploading images
                uploadStep.removeCurrentlyUploading(filepath);

            }

和我的取消通知方法：

public static void CancelNotification(Context ctx, int notifyId){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
    nMgr.cancel(notifyId);
}

答案最终很简单;只需将以下行添加到我更新的通知中：

.setTicker("Upload Complete")

这是完整的代码：

Builder uploadedBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.logo)
                .setContentTitle("Upload complete")
                .setTicker("Upload Complete")
                .setContentText(Constant.totalUploadedImages.get()+" " + uploaded_count + " uploaded")
                .setAutoCancel(true);
                Notification uploadNotif = uploadedBuilder.build();
                mNotificationManager.notify(Constant.NOTIFICATION_UPLOADING_ID, uploadNotif);   
                Constant.totalUploadedImages.getAndSet(0);      

            }
