使用GreenDroid ItemAdapter與常規活動

我想使用GreenDroid的ItemAdapter和自定義列表項與常規ListActivity（或未來在SherlockListActivity中）。我提取了ItemAdapter，Item和View類並創建了一個自定義項目。（注：昨天我試着用整個GreenDroid項目同樣的事情，所以，有一個與我的新解壓縮的項目沒有問題）使用GreenDroid ItemAdapter與常規活動

我的例子ListActivity：

public class TestActivity extends ListActivity { 
    /** Called when the activity is first created. */ 

    ItemAdapter adapter; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     adapter=new ItemAdapter(this); 
     adapter.add(new TextItem("test")); 
     adapter.notifyDataSetChanged(); 
     setListAdapter(adapter); 
    } 
}

崩潰，並給出了這樣的輸出：

我覺得最重要的部分是：

java.lang.UnsupportedOperationException: Can't convert to dimension: 
type=0x2 01-30 17:07:33.983: E/AndroidRuntime(21042):

應該有這樣在GreenDroid的維度文件中進行計算。

如何解決？如何在沒有GDActivity的情況下使用GreenDroid的ItemAdapter？

這實際上不是一個GDActivity問題，而是一個主題問題。我目前正在使用ActionbarSherlock 4的精簡版GreenDroid。

要解決您的問題，您需要製作一個擁有parent = Theme.Sherlock的主題。不幸的是，您不能添加多個父母，因此您需要將GD主題的內容複製並粘貼到您的自定義主題中。

礦看起來是這樣的：theme.xml

<resources> 
    <style name="Theme.MyTheme" parent="Theme.Sherlock"> 
     <item name="actionBarStyle">@style/Widget.MyTheme.ActionBar</item> 
     <item name="android:actionBarStyle">?actionBarStyle</item> 

     <!-- GreenDroid stuff --> 
     <item name="gdTextAppearance">@style/TextAppearance</item> 
     <item name="gdTextAppearanceLarge">@style/TextAppearance.Large</item> 
     <item name="gdTextAppearanceMedium">@style/TextAppearance.Medium</item> 
     <item name="gdTextAppearanceSmall">@style/TextAppearance.Small</item> 
     <item name="gdTextAppearanceSeparator">@style/TextAppearance.Separator</item> 

     <item name="gdDrawableWidth">@dimen/gd_drawable_width</item> 
     <item name="gdDrawableHeight">@dimen/gd_drawable_height</item> 
     <item name="gdDrawableMargin">@dimen/gd_drawable_margin</item> 

     <item name="gdItemViewPreferredHeight">@dimen/gd_item_view_height</item> 
     <item name="gdItemViewPreferredHalfHeight">@dimen/gd_item_view_half_height</item> 
     <item name="gdItemViewPreferredPaddingLeft">@dimen/gd_item_view_padding_left</item> 
     <item name="gdSeparatorItemViewPreferredHeight">@dimen/gd_separator_item_view_height</item> 

     <item name="gdTextItemViewStyle">@style/GreenDroid.Widget.ItemView.TextItemView</item> 
     <item name="gdLongTextItemViewStyle">@style/GreenDroid.Widget.ItemView.LongTextItemView</item> 
     <item name="gdDescriptionItemViewStyle">@style/GreenDroid.Widget.ItemView.DescriptionItemView</item> 

     <item name="gdSeparatorItemViewStyle">@style/GreenDroid.Widget.ItemView.SeparatorItemView</item> 

     <item name="gdProgressItemViewStyle">@style/GreenDroid.Widget.ItemView.ProgressItemView</item> 
     <item name="gdProgressItemViewStyleText">@style/GreenDroid.Widget.ItemView.ProgressItemView.Text</item> 
     <item name="gdProgressItemViewStyleProgressBar">@style/GreenDroid.Widget.ItemView.ProgressItemView.ProgressBar</item> 

     <item name="gdDrawableItemViewStyle">@style/GreenDroid.Widget.ItemView.DrawableItemView</item> 
     <item name="gdDrawableItemViewStyleText">@style/GreenDroid.Widget.ItemView.DrawableItemView.Text</item> 
     <item name="gdDrawableItemViewStyleDrawable">@style/GreenDroid.Widget.ItemView.DrawableItemView.Drawable</item> 

     <item name="gdSubtitleItemViewStyle">@style/GreenDroid.Widget.ItemView.SubtitleItemView</item> 
     <item name="gdSubtitleItemViewStyleText">@style/GreenDroid.Widget.ItemView.SubtitleItemView.Text</item> 
     <item name="gdSubtitleItemViewStyleSubtitle">@style/GreenDroid.Widget.ItemView.SubtitleItemView.SubtitleText</item> 

     <item name="gdSubtextItemViewStyle">@style/GreenDroid.Widget.ItemView.SubtextItemView</item> 
     <item name="gdSubtextItemViewStyleText">@style/GreenDroid.Widget.ItemView.SubtextItemView.Text</item> 
     <item name="gdSubtextItemViewStyleSubtext">@style/GreenDroid.Widget.ItemView.SubtextItemView.Subtext</item> 

     <item name="gdThumbnailItemViewStyle">@style/GreenDroid.Widget.ItemView.ThumbnailItemView</item> 
     <item name="gdThumbnailItemViewStyleText">@style/GreenDroid.Widget.ItemView.ThumbnailItemView.Text</item> 
     <item name="gdThumbnailItemViewStyleSubtitle">@style/GreenDroid.Widget.ItemView.ThumbnailItemView.Subtitle</item> 
     <item name="gdThumbnailItemViewStyleThumbnail">@style/GreenDroid.Widget.ItemView.ThumbnailItemView.Thumbnail</item> 
    </style> 
</resources>

確保您的應用工作的主題設置爲自定義主題。

如果你在意，你可以從https://github.com/croemmich/GreenDroid上獲取我的精簡版GD。我已經刪除了所有的ActionBar的東西。
