帶有ListView的SearchView更改物品位置，需要其他活動的確切物品ID

Question

您好，我有一個搜索視圖來過濾短列表中的結果。我目前使用整數傳遞到下一個活動來加載需要顯示的內容。但是，如果您搜索，則您搜索的項目現在位於第0個位置，即第一個項目所在的位置。那麼，如何爲此設置一個唯一的ID系統，或者我可以爲此調用一個方法嗎？

@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; 
}

我有同樣的問題，我這樣固定的話，請注意我想我的科特林邏輯轉換成Java，糾正我，如果有錯，首先我們需要實現我們的過濾邏輯，檢查onQueryTextChange在執行邏輯
