嘗試刪除@RemoteViews標記，如果你有一個，那對我有用。正在絞盡腦汁想出來。 – DeliveryNinja 2011-03-20 15:36:27

什麼是com.org.BatteryManager.BatteryView？

如果你想使用自定義視圖，那麼它是可能的。實現它的方法是在Java中創建一個自定義視圖類，以擴展一些基本視圖組件類。

例如，我在很多應用程序中使用自定義圖庫組件。畫廊類只會在與默認行爲不同的滑動中左右移動一幀。

，我把我的自定義庫的方式是擴展了基本庫類 -

package com.testing.whatever; 

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

在我的XML代碼

然後，代碼看起來類似於你已經有 -

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

我懷疑你得到你的錯誤，因爲你還沒有編碼com.org.BatteryManager.BatteryView或它在你的java文件中的錯誤的地方。

這不適用於應用程序小部件。應用程序小部件不能使用自定義類。 – CommonsWare 2012-11-12 17:35:23

我有同樣的困惑問題。爲了解決這個問題，你的自定義視圖應該提供一個帶有兩個參數的構造函數：Context和AttributeSet，提供建議here。
