带有 ListView 的 SearchView 更改项目位置，需要其他活动的确切项目 ID

Question

您好，我有一个搜索视图来过滤短列表中的结果。我目前使用一个整数传递给下一个活动来加载需要显示的内容。但是，如果您搜索，您搜索的项目现在位于位置 0，这就是第一个项目。那么我该如何为此设置一个唯一的 ID 系统，或者我可以为此调用一种方法吗？

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search_clinics);
    listView = (ListView) findViewById(R.id.listView);
    final ArrayList<String> clinicInfoArrayList = new ArrayList<String>();
    clinicInfoArrayList.add("Phoenix Urgent Care \n 3931 E Camelback Rd, Phoenix, AZ 85018");
    clinicInfoArrayList.add("Pain Stop North Phoenix Clinic \n 3329 East Bell Road, Suite A2-A5, Phoenix, AZ 85032");
    clinicInfoArrayList.add("The Little Clinic \n 2727 W Bell Rd, Phoenix, AZ 85053");
    clinicInfoArrayList.add("Native Health \n Building C, 4041 N Central Ave, Phoenix, AZ 85012");
    clinicInfoArrayList.add("Allied Clinic, PLLC \n 1147 E Glendale Ave, Phoenix, AZ 85020");
    clinicInfoArrayList.add("Neighborhood Clinic \n 1929 W Fillmore St, Phoenix, AZ 85009");
    clinicInfoArrayList.add("MinuteClinic \n 4742 E Indian School Rd, Phoenix, AZ 85018");


    mSearchView = (SearchView) findViewById(R.id.menu_search);


    listView.setTextFilterEnabled(true);

    final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_list_item_1,
            clinicInfoArrayList);

    listView.setAdapter(arrayAdapter);


    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapter, View v, int position,
                                long arg3) {



            Intent intent = new Intent(SearchClinics.this,ClinicInfoView.class);


            int something = (int)arrayAdapter.getItemId(position);



         intent.putExtra("Another", something);
        startActivity(intent);
        }
    });


    }


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.search_menu, menu);

    SearchManager searchManager = (SearchManager)
            getSystemService(Context.SEARCH_SERVICE);
    MenuItem searchMenuItem = menu.findItem(R.id.menu_search);
   mSearchView = (SearchView) searchMenuItem.getActionView();

    mSearchView.setSearchableInfo(searchManager.
            getSearchableInfo(getComponentName()));


    mSearchView.setIconifiedByDefault(false);
    mSearchView.setOnQueryTextListener(this);
    mSearchView.setSubmitButtonEnabled(true);
    mSearchView.setQueryHint("Search Here");
    return true;

}


@Override
public boolean onQueryTextChange(String newText) {
    if (TextUtils.isEmpty(newText)) {
        listView.clearTextFilter();
    } else {
        listView.setFilterText(newText.toString());
    }
    return true;
}

 @Override
 public boolean onQueryTextSubmit(String query) {
    return true;
 }
