Android的cursoradapter過濾器列表視圖

Question

我想用cursoradapter過濾我的列表視圖。這是我迄今爲止所嘗試的：

CustomAdapter adapter; 
Cursor cursor; 

etSearch.addTextChangedListener(new TextWatcher(){ 

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

     } 

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

     } 

     public void onTextChanged(CharSequence cs, int arg1, int arg2, 
       int arg3) { 
      // TODO Auto-generated method stub 

      adapter.getFilter().filter(cs.toString()); 

     } 

    }); 

cursor = dbHelper.getAllItemInventoryListings(); 

    adapter = new CustomAdapter(this, cursor); 

    lv.setAdapter(adapter); 
    lv.setTextFilterEnabled(true); 

    adapter.setFilterQueryProvider(new FilterQueryProvider() { 

     @Override 
     public Cursor runQuery(CharSequence constraint) { 

      String strItemCode = constraint.toString(); 
      return dbHelper.getAllItemInventoryListings(strItemCode); 

     } 
    }); 

當我嘗試它不過濾。什麼似乎是錯的？您的幫助將不勝感激。謝謝。

嘗試添加adapter.notifyDataSetChanged();後adapter.getFilter().filter(cs.toString());
