Question

当我搜索事件时，它可以工作，但是当我单击事件时，即使它更改了ListView，但在ListView上却给了我错误的项目。我应该怎么做才能使其正常工作？

public class Searchable extends Activity {

ListView lv;
SearchView sv;

问题已解决。使用代码：

在arraylist中。

    @Override
    public String toString() {
        return name;
    }

}

在我的可搜索内容中：添加了这一行。

final Adapter adapter=new Adapter(this, getPlayers());
lv.setAdapter(adapter);


lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //ArrayListe item= (ArrayListe) Adapter.getItem(position);

        String name = lv.getItemAtPosition(position).toString();

        for (int index = 0; index < names.length; index++){
            if (name.equals(names[index])) {
                position = index;
                break;
            }
        }

        if(position==0){
            startActivity(new Intent(view.getContext(), Activity1.class));
            MainActivity.editClick++;
        }
