Listview- filter Android

Question

我有一個ListView與單個行中的多個TextView。 TextView值是名稱，組名，日期和一些隱藏字段。並在這ListView以外的微調。一旦我從Spinner ListView中選擇物品需要過濾。那是另一排將會消失。我已嘗試setVisibility()方法，但效果不佳。我正在使用簡單的適配器。我怎樣才能做到這一點。請幫幫我。

我的樣例代碼爲：

Spinner draft_filter = (Spinner) findViewById(R.id.draft_filter); 
    draft_filter.setOnItemSelectedListener(new OnItemSelectedListener() { 



        public void onItemSelected(AdapterView<?> arg0, View arg1, 
          int arg2, long arg3) { 
         // TODO Auto-generated method stub 
         Spinner draft_spinner = (Spinner) arg0; 
         String selected_string = (String) draft_spinner.getSelectedItem(); 
    //Save this String and filter the listview using this 
    } 

        public void onNothingSelected(AdapterView<?> arg0) { 
         // TODO Auto-generated method stub 

        } 
       }); 
    ListView level1 = (ListView) findViewById(R.id.listview); 
    level1.setOnScrollListener(new OnScrollListener() { 

        public void onScrollStateChanged(AbsListView view, int scrollState) { 
         // TODO Auto-generated method stub 

        } 

        public void onScroll(AbsListView view, int firstVisibleItem, 
          int visibleItemCount, int totalItemCount) { 
         // TODO Auto-generated method stub 
         for (int i=0; i<level1.getChildCount(); i++) 
         { 
    // Set the Visibility of the row here 
    } 
       }); 

    //For loading listview 
//Here fillmaps is the arraylist contains hashmap values 
    String[] drafts = new String[] { "child_name", "age"}; 
    int[] controls = new int[] { R.id.item1, R.id.item2}; 
    adapter = new SimpleAdapter(getApplicationContext(), fillMaps, 
         R.layout.draft_observation_list_layout, drafts, controls); 
       level1.setAdapter(adapter); 

如何過濾列表視圖這個請大家幫忙。

Answer 1

我試過很多東西，但解決的方法很簡單：

((SimpleAdapter) MyActivity.this.adapter).getFilter().filter(filter_text); 

Answer 2

每當Spinner項目值隨過濾列表值發生變化時調用適配器。
