我想在我的Android应用程序中搜索列表视图，所以我使用了android搜索视图小部件。我成功实现了搜索，但问题是在搜索后到达。 当我搜索它给我过滤结果，但当我点击过滤的项目，它给我错误的位置。 请帮帮我。

您需要在mcontact按钮中单击
更新适配器mMyContactsAdapter.getItem(position);
Contacts mList = getSearchResults(sv.getQuery().toString()).get(position);
number = mList.get(position).getNumber();
email = mList.get(position).getEmail();

问题是搜索过滤了内部适配器coverList。因此，在适配器中项目的位置是OK。
但是，然后，您调用适配器的外部（在课堂上）mList。在那一点上，你正在寻找没有过滤器的原始数组。所以这个立场是错误的。
您需要从适配器中的已过滤阵列中恢复联系人。所以在您的 MainActivity ：
中mcontact.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
number = mMyContactsAdapter.getItem(position).getNumber();
email = mMyContactsAdapter.getItem(position).getEmail();
view.setSelected(true);
}
});
