另外，我使用自定义列表视图，并希望从搜索视图中输入应该与列表视图项特定文本视图相关的关键词进行过滤。

I have an Activity which has a Action Bar on the top with a Search View. Also i am using Custom List View and want to filter from the key words entered in the search view should be associated with a particular text view in the List View Item.

：
。adapter.getFilter（）过滤（Text.toString（））;在你BaseAdapter类实现你的过滤器。
这里是样本code：

in your onQueryTextChange(String Text) method of Listener use: adapter.getFilter().filter(Text.toString()); and implement your filter in your BaseAdapter class. here is the sample code:

 @Override
        public Filter getFilter() 
        {
             return filter;
        }

     private GameFilter filter;

     private class GameFilter extends Filter 
     {
         public GameFilter() { }
            @Override
                  protected FilterResults performFiltering(CharSequence constraint) {
                       FilterResults oReturn = new FilterResults();
                      ArrayList<ItemDetails> results = new ArrayList<ItemDetails>();
                    if (orig == null)
                      orig = itemDetailsrrayList;                    
                      if (constraint != null)
                   {
                        if (orig != null && orig.size() > 0) {
                          for (ItemDetails g : orig) {
                                  if (g.getName().toLowerCase().contains(constraint.toString().toLowerCase()))
                                 results.add(g);
                        }
                   }
                       oReturn.values = results;
                    }
                     return oReturn;
                  }

                 @SuppressWarnings("unchecked")
                 @Override
                protected void publishResults(CharSequence constraint, FilterResults results)
                 {
                     itemDetailsrrayList = (ArrayList<ItemDetails>)results.values;
                   notifyDataSetChanged();
                 }
            }
