Listview在Android中填充

在我的應用程序中，我有1個listview，使用arrayadapter從數據庫填充數據。Listview在Android中填充

這裏是下面的代碼：

public void onClick(View v) { 
        // TODO Auto-generated method stub 

         Cursor c = db.gethouseholdTitle(); 
         startManagingCursor(c); 
//     if(cat.equals("Income")) 
//     { 
////       System.out.println("inside if="+select); 
////       Cursor cin = db.income(); 
         String[] fromdes = new String[] {db.KEY_DATE,db.KEY_DESC,db.KEY_INCOME,db.KEY_TOTAL}; 
         int[] todes = new int[] {R.id.text1 ,R.id.text3,R.id.text5,R.id.text7}; 
         SimpleCursorAdapter notes = 
            new SimpleCursorAdapter(this, R.layout.columnview, c, fromdes, todes); 
         // System.out.println("notes="+notes.getCount()); 
         // setListAdapter(notes);  
          lv.setAdapter(notes); 

       }

但是示值誤差：

The constructor SimpleCursorAdapter(new View.OnClickListener(){}, int, Cursor, String[], int[]) is undefined

什麼，我在做advance.I認爲wrong.Thanks我們不能能填補點擊功能裏面光標適配器??

在onclick的背景下被改變。所以，你必須在放置'** this **'之前放置YourActivityName。提供YourActivity的背景。 – 2012-07-16 13:42:18

改變這一行：

SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.columnview, c, fromdes, todes);

到這一點：

SimpleCursorAdapter notes = new SimpleCursorAdapter(MyActvity.this, R.layout.columnview, c, fromdes, todes);

這裏MyActivity應該是你的活動的實際名稱。

與此同時，我會從SimpleCursorAdapter的javadoc提請您注意以下摘錄：

This constructor is deprecated. This option is discouraged, as it results in Cursor queries being performed on the application's UI thread and thus can cause poor responsiveness or even Application Not Responding errors. As an alternative, use LoaderManager with a CursorLoader.
