getView（）をオーバーライドしてリストアイテムのカスタムビューを提供するカスタムArrayAdapterを含むListFragmentがあります。
private class DirListAdaptor extends ArrayAdapter<DirItem> {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View aView = convertView;
if (aView == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// TODO: can we not access textViewResourceId?
aView = vi.inflate(R.layout.dir_list_entry, parent, false);
}
etc...
dir_list_entry.xmlは次のとおりです。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight">
<ImageView
android:id="@+id/dir_list_icon"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginRight="6dp"
android:src="@drawable/ic_launcher"
/>
<TextView
android:id="@+id/dir_list_details"
android:textAppearance="?android:attr/textAppearanceListItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/dir_list_icon"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:singleLine="true"
android:ellipsize="marquee"
android:textSize="12sp"
android:text="Details" />
<TextView
android:id="@+id/dir_list_filename"
android:textAppearance="?android:attr/textAppearanceListItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/dir_list_icon"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_above="@id/dir_list_details"
android:layout_alignWithParentIfMissing="true"
android:gravity="center_vertical"
android:textSize="14sp"
android:text="Filename"/>
</RelativeLayout>
奇妙なことに、これはAndroid 4.1エミュレーターでは正常に機能しますが、Android2.3では次のエラーが発生します。

私は明らかにフラグメントサポートのためにAndroidサポートライブラリを使用しています。
カスタムリストビューエントリを膨らませるのに問題があるようです。これはディメンションと関係がありますが、なぜJellyBeanで機能するのでしょうか。この分野で何か変わったことはありますか？
