在列表視圖中搜索數據存儲在數據庫中

我有一個listview不同的數據存儲在數據庫中，當我點擊特定的數據時，它將顯示該數據的細節，並且我還使用了適配器類的位置listview它會獲取要顯示的數據的詳細信息。在列表視圖中搜索數據存儲在數據庫中

我需要添加搜索listview和從結果listview，如果我點擊數據，它應該顯示的細節。請，任何人都可以爲此提供代碼。

列表視圖是工作，但我DONO添加搜索該列表視圖，從數據庫 – saran

[Rû有Mr.saran獲取詳細信息？你在這裏找到解決方案嗎？ –

您可以使用FilterQueryAdapter界面如下：

DataBaseHelper myDbHelper = new DataBaseHelper(this); 
    FilterQueryProvider fqp = new myFilterQueryProvider(myDbHelper); 
     <YourCursorAdapter>.setFilterQueryProvider(fqp); 
     <YourListView>.setTextFilterEnabled(true); 
     <YourEditTextSearchbox>.addTextChangedListener(new TextWatcher() 
     { 
      @Override 
      public void onTextChanged(CharSequence s, int start, 
        int before, int count) { 
       // TODO Auto-generated method stub 

      } 
      @Override 
      public void beforeTextChanged(CharSequence s, int start, 
        int count, int after) { 
       // TODO Auto-generated method stub 

      } 
      @Override 
      public void afterTextChanged(Editable s) { 
       // TODO Auto-generated method stub 
       this.adaptr.getFilter().filter(s); 
      }    
     }); 

    public class myFilterQueryProvider implements FilterQueryProvider { 
    DataBaseHelper myDbHelper; 
    public myFilterQueryProvider(DataBaseHelper mdb) { 
     myDbHelper = mdb; 
    } 
    public Cursor runQuery(CharSequence constraint) 
    { 

     try { 
      myDbHelper.openDataBase(); 
     }catch(SQLException sqle){ 
      throw sqle; 
     } 

     sql =""; //Your DB Query here 
     Cursor cursor = myDbHelper.getLobbyView(sql); 
     return cursor; 
    } 
}

不，我沒有得到解決方案，因爲我使用了適配器類。我已經用我的代碼更新了這個問題。 – saran

我有一個列表視圖，而在搜索列表視圖得到減少根據搜索，但問題是，通過列表的位置我會在onclick中獲取詳細信息，但是當列表視圖更改它沒有得到的細節。 – saran

如果您正在使用a DB

只需獲取一個Edittext textwatcher。
每個框TextChanged調用DB「LIKE」查詢，以顯示你的結果
