DialogFragment中ListView的子项显示不可用

昨天碰到一个很奇怪的总是:DialogFragment中ListView的子项显示不可用

有两个同类型的ListView,相同的Adapter,相同的view,内容也相同.唯一区别是一个是放到Fragment中,一个是放到DialogFragment中,结果放到Fragment中显示正常.放到DialogFragment中显示不下常,所有子项全变成灰色了(就是 enable=false的那种灰色).原因不明...

1.这是放在Fragment中ListView中的子项,显示正常

2.这是放在DialogFragment中的ListView中的子项,显示为灰色.

虽然现在显示的两个item长的不一样.但是我自己也用相同的view,相同的adapter试过,放到DialogFragment中的item就是灰色的,不知道什么原因.

现在还没解决,先mark

Code:

1. normal ListView:

public class SearchFragment extends BaseFragment{
    ListView searchListView;
    SearchListAdapter searchListAdapter;
    …

    init(){
        searchListAdapter = new SearchListAdapter(getActivity(), searchList);
        searchListView.setAdapter(searchListAdapter);
    }
}

class SearchListAdapter{
    	public View getView(int position, View convertView, ViewGroup parent) {
		if (convertView == null) {
			convertView = viewHelper.getView(parent, list, position);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}

		return convertView;
	}

	private static class ViewHelper {
		Context context;

		public ViewHelper(Context context) {
			this.context = context;
		}


		public View getView(ViewGroup parent, List<Apply> list, int position) {
			return getView(parent, list.get(position), position);
		}

		private View getView(ViewGroup parent, Apply item, int position) {
			LayoutInflater inflater = LayoutInflater.from(context);
			View convertView = inflater.inflate(R.layout.search_list_item, parent, false);

			SearchItemViewHolder holder = new SearchItemViewHolder(convertView);
			holder.binderData(position, item);
			convertView.setTag(holder);

			return convertView;
		}
	}
}

总算解决了:

在listview的子项中显式调用 setColor,setstyle之类的...

不过还是不太清楚不设置color时,设计UI时显示正常,实机测试为啥就不对了呢?
