将GreenDroid ItemAdapter与常规活动一起使用

Question

我想将GreenDroid的ItemAdapter和自定义列表项与常规ListActivity一起使用（或在SherlockListActivity中的Future中）。我提取了ItemAdapter、Item和View类，并创建了一个自定义项目。（注意：昨天我使用整个GreenDroid项目尝试了同样的方法。所以，我的新提取项目没有问题）

我的示例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);
    }
}

崩溃并给出以下输出：

我认为最重要的部分是：

GreenDroid的维度文件中应该有一些内容。

如何修复？没有GDActivity，如何使用GreenDroid的ItemAdapter？

Answer 1

这实际上不是一个GDActivity问题，而是一个主题问题。我目前正在使用一个精简版的GreenDroid和ActionbarSherlock 4。

为了解决您的问题，您需要制作一个parent=theme.Sherlock的主题。不幸的是，您无法添加多个parent，因此您需要将GD主题的内容复制并粘贴到您的自定义主题中。

我的是这样的：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>

确保将活动的主题设置为自定义主题。

如果你介意的话，你可以从https://github.com/croemmich/GreenDroid.我已经删除了ActionBar的所有内容。
