自定义通知：java.lang.RuntimeException的：坏数组的长度 [英] Custom notification: java.lang.RuntimeException: bad array lengths

问题描述

我试图用使用谷歌的距离样品这里（第<一href="http://developer.android.com/guide/topics/ui/notifiers/notifications.html#CustomExpandedView">Creating自定义通知布局）。 自从我使用这个确切的code我有一个的RuntimeException 每隔几次通知解雇了。

I'm trying to use custom notifications in my Android application using Google's sample from here (section Creating a Custom Notification Layout). Since I'm using this exact code I got a RuntimeException every few times a notification is fired.

我的堆栈跟踪：

我的code：

My code:

private final Intent updateInProgressIntent = new Intent(this.context, PodcastListActivity.class);
private RemoteViews updateInProgressContentView = null;
private PendingIntent updateInProgressPendingIntent = null;
private Notification updateInProgressNotification = null;
...
    @Override 
    public void onCreate() { 
        super.onCreate();    
...
        this.updateInProgressPendingIntent = PendingIntent.getActivity(this, UPDATE_INPROGRESS_NOTIFICATION_ID, 
        this.updateInProgressIntent, PendingIntent.FLAG_UPDATE_CURRENT);     
        this.updateInProgressContentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
...
    }

    public void notifyUpdateProgress(final int index, final int size, final Podcast podcast) {

        this.updateInProgressContentView.setImageViewBitmap(
                R.id.image, ActivityHelper.getBitmap(context, podcast.getThumbnailAsset()));
        this.updateInProgressContentView.setTextViewText(R.id.title, "some msg");
        this.updateInProgressContentView.setTextViewText(R.id.text, podcast.getName());
        this.updateInProgressNotification.contentView = this.updateInProgressContentView;       
        this.updateInProgressNotification.contentIntent = this.updateInProgressPendingIntent;               
        this.notificationManager.notify(UPDATE_INPROGRESS_NOTIFICATION_ID, this.updateInProgressNotification);

        ...
        }       

如果我更换一个标准的自定义通知（与 setLatestEventInfo（））我没有问题。

If I replace the custom notification with a standard one (with setLatestEventInfo()) I have no problems.

推荐答案

好了，我终于找到了解决办法。 不能重复使用同一个远程视窗的对象像我一样！ 我创建了远程视窗中的onCreate（）方法，然后我设置其属性在notifyUpdateProgress（）。 如果我创建notifyUpdateProgress（对象），只是使用它之前，我不再有例外。

Ok, so I finally find the solution. You cannot re-use the same RemoteView object like I did! I was creating the RemoteView in the onCreate() method, then I was setting its attributes in notifyUpdateProgress(). If I create the object in notifyUpdateProgress() just before using it, I'm not having exception anymore.
