android - 搜索后使用 android 搜索 View 小部件搜索未显示正确位置

Question

我想在我的 android 应用程序中搜索 ListView ，所以我为此使用了 android 搜索 View 小部件。我成功地实现了搜索，但问题是在搜索后出现。当我搜索时，它会给我过滤后的结果，但是当我单击过滤后的项目时，它会给我错误的位置。请帮我解决这个问题。

主 Activity

public class MainActivity extends AppCompatActivity implements 
SlidingPaneLayout.PanelSlideListener,
  android.widget.SearchView.OnQueryTextListener

   MyContactsAdapter mMyContactsAdapter;
   SlidingPaneLayout sp;
   Context context=this;
   android.widget.SearchView sv;
    public static String number;
   public static String email;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    context = this;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    right = (RelativeLayout) findViewById(R.id.rightSide);
    left = (RelativeLayout) findViewById(R.id.leftSide);
    mcontact = (ListView) findViewById(R.id.contact);

    sv= (android.widget.SearchView) findViewById(R.id.searchView1);

    sp = (SlidingPaneLayout) findViewById(R.id.Sliding);
    assert sp != null;
    sp.setSliderFadeColor(Color.TRANSPARENT);
    sp.openPane();
    mList = new ArrayList<Contacts>();
    readContacts();
    mcontact.setTextFilterEnabled(true);

    mcontact.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id)

Answer 1

问题是搜索正在过滤适配器coverList内部的数组。所以，在适配器中，项目的位置是确定的。

但是随后，您调用适配器的外部 操作(在类中)mList。在那一点上，您正在查看没有过滤器的原始数组。所以位置不对。

您需要从适配器中过滤后的数组中恢复联系人。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);
    }
});
