由於切換按鈕的空指針？

Question

我用這個代碼來設置視圖

setContentView(R.layout.main_activity); 

和我的話，我有這樣的代碼來獲得infromation了在屏幕上

Cursor MainPageCursor = databaseHelper.fetchAllReminders(); 
    startManagingCursor(MainPageCursor); 


    String[] empty = new String[] { DatabaseStore.MUTE_TITLE, DatabaseStore.START_KEY_TIME, DatabaseStore.END_KEY_TIME, DatabaseStore.COVERT_DAYS }; 



     int[] notempty = new int[]{R.id.text1,R.id.text2, R.id.text4, R.id.text5}; 
     SimpleCursorAdapter mainPageList = new SimpleCursorAdapter(this, R.layout.editinfo_row,MainPageCursor, empty, notempty); 
     setListAdapter(mainPageList); 

，但我的問題是我需要得到一個切換按鈕到simplecursoradapter中的每個項目行，但如果我把它放入simplecursoradapter佈局R.layout.editinfo_row我得到一個空指針異常我如何解決這個問題？

更新 - editinfo_row.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

聽起來像是你應該實現自己的適配器，覆蓋SimpleCursorAdapter.getView()得到你想要的東西。 Here是我找到的一個示例
