尝试删除@RemoteViews标记，如果你有一个，那对我有用。正在绞尽脑汁想出来。 – DeliveryNinja 2011-03-20 15:36:27

什么是com.org.BatteryManager.BatteryView？

如果你想使用自定义视图，那么它是可能的。实现它的方法是在Java中创建一个自定义视图类，以扩展一些基本视图组件类。

例如，我在很多应用程序中使用自定义图库组件。画廊类只会在与默认行为不同的滑动中左右移动一帧。

，我把我的自定义库的方式是扩展了基本库类 -

package com.testing.whatever; 

public class CustomGallery extends Gallery { 
    //CODE OVERRIDES HERE 
}

在我的XML代码

然后，代码看起来类似于你已经有 -

<com.testing.whatever.CustomGallery android:layout_width="fill_parent" android:layout_height="fill_parent" />

我怀疑你得到你的错误，因为你还没有编码com.org.BatteryManager.BatteryView或它在你的java文件中的错误的地方。

这不适用于应用程序小部件。应用程序小部件不能使用自定义类。 – CommonsWare 2012-11-12 17:35:23

我有同样的困惑问题。为了解决这个问题，你的自定义视图应该提供一个带有两个参数的构造函数：Context和AttributeSet，提供建议here。
