Listview在Android中填充

在我的应用程序中，我有1个listview，使用arrayadapter从数据库填充数据。Listview在Android中填充

这里是下面的代码：

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); 

       }

但是示值误差：

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

什么，我在做advance.I认为wrong.Thanks我们不能能填补点击功能里面光标适配器??

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

改变这一行：

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

到这一点：

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

这里MyActivity应该是你的活动的实际名称。

与此同时，我会从SimpleCursorAdapter的javadoc提请您注意以下摘录：

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.
