列表视图上的搜索过滤器在单击项目时返回错误结果 [英] Search filter on listview returns wrong results on item click
问题描述
我做了相当多的研究，发现了3个与我的问题有关的案例.
I have done my fair share of research and found three cases related to my problem.
我并不是说我的案子是独一无二的，而是我不能用自己的绳索使他们的回答对我有用.
I am not saying that my case is unique or anything,it is jus that i cannot make their answers work for me with my cord.
问题::我有一个 listview 顶部被 edit文本过滤.但是，当我单击搜索的项目时，我得到了选择另一张图像的结果.文本可以正常工作，但是图像是问题所在.
PROBLEM: I have a listview getting filtered by an edit text on top.However when i click on the item searched i get the result of another image being selected.Text works fine but images is the problem.
例如:列表中的行包含图像A，B，C，D
For example: list has rows with images A,B,C,D
在搜索C时，您得到的结果被过滤为C.但是单击它会显示A的图像.就像位置不会更改图像，而是使用原始的 ArrayList 适配器位置
On searching C you get the result filtered as C.But clicking on it results on showing image from A.It is like the position does not change for the images but uses the original ArrayList adapter position.
任何帮助将不胜感激.
我的适配器:

List<Model> mStringFilterList;
ValueFilter valueFilter;

this.activity = activity;
this.modelItems = modelItems;
mStringFilterList = modelItems;

mDefaultImageId = defaultImage;

@Override

thumbNail.setTag(position);
// title
title.setText(m.getTitle());

String genreStr = "";

genreStr += str + ", ";
}
genreStr = genreStr.length() > 0 ? genreStr.substring(0,

genre.setText(genreStr);
return convertView;

推荐答案
您可以更改代码
String name = ((TextView) view.findViewById(R.id.title)).getText().toString();
bitmap = ((Model) modelList.get(position)).getThumbnailUrl();
String rate = ((TextView) view.findViewById(R.id.rating)).getText().toString();
String genres = ((TextView) view.findViewById(R.id.genre)).getText().toString();
到
Model model=(Model)adapter.getItem(position);
它将获得您单击的位置的模型，并将该模型作为序列化或您要执行的操作传递.
It will get the model on which position you clicked and pass this model as Serialized or what you want to do.
希望这可以解决问题.
