搜索時，我不得不數據庫

Question

我有數據庫，但我不kwow如何使用列表視圖搜索。我搜索互聯網，但我用「串」，但我有一個數據庫，所以我不能使用字符串，請幫助使用搜索列表視圖中，從數據庫中加載，而不是設置字符串產品[] = {}固定字符串

數據

lv = (ListView) findViewById(R.id.listView); 

    wordAdapter = new ArrayAdapter<Word>(this, R.layout.list_item, 
      R.id.product_name); 
    lv.setAdapter(adapter); 
    dbHandler=new DatabaseHandler(getApplicationContext()); 


    inputSearch = (EditText) findViewById(R.id.inputSearch); 
    inputSearch.addTextChangedListener(new TextWatcher() { 

     @Override 
     public void onTextChanged(CharSequence cs, int arg1, int arg2, 
       int arg3) { 
      MainActivity.this.wordAdapter.getFilter().filter(cs); 

     } 


     @Override 
     public void beforeTextChanged(CharSequence arg0, int arg1, 
       int arg2, int arg3) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
     public void afterTextChanged(Editable arg0) { 
     // TODO Auto-generated method stub 


    } 
    }); 

    and this is database
