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

你好，我有一个搜索视图来筛选短列表中的结果。 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，则您搜索的项目现在位于第一个项目所在的位置0。 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个方法吗？

@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; }

我有同样的问题，我这样解决它，注意我试图将我的kotlin逻辑转换为java，纠正我，如果有任何错误，首先我们需要实现我们的过滤逻辑，检查onQueryTextChange实现逻辑
