Using GreenDroid ItemAdapter with regular Activity

Question

I want to use GreenDroid's ItemAdapter and custom list items with a regular ListActivity (or in Future in SherlockListActivity). I extracted ItemAdapter, Item and View classes and created a custom project. (Note: Yesterday I tried the same thing using whole GreenDroid project. So, there is no problem with my new extracted project)

My example 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);
    }
}

crashes and gives this output:

I think the most important part is:

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

There should be something in GreenDroid's dimension files.

How to fix? How can be used GreenDroid's ItemAdapter without GDActivity?

Answer 1

It's not actually a GDActivity issue, but rather a theme issue. I'm currently using a stripped down version of GreenDroid with ActionbarSherlock 4.

To remedy your problem you will need to make a theme that has parent=Theme.Sherlock. Unfortunately you cannot add multiple parents, so you will need to copy and paste the contents of the GD theme into your custom theme.

Mine looks something like this: 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>

Make sure to set your activitie's theme to your custom theme.

If you care, you can grab my stripped down version of GD from https://github.com/croemmich/GreenDroid. I've removed all of the ActionBar stuff.
