我想刪除一行中的列表視圖使用該行中的按鈕沒有cursor.requery，因爲它是貶值

Question

我正在使用3個TextViews和1按鈕的CursorAdapter。我想在按下按鈕時從數據庫中刪除條目。
注：存在於這個很多職位，但他們都使用現在貶值「cursor.requery」

@Override 
public void bindView(View view, final Context context, final Cursor cursor) { 

    TextView viewID = (TextView) view.findViewById(R.id.viewID); 
    TextView viewAmount=(TextView) view.findViewById(R.id.viewAmount); 
    TextView viewCategory=(TextView) view.findViewById(R.id.viewCategory); 
    Button buttonDelete = (Button) view.findViewById(R.id.buttonDelete); 

    final int id = cursor.getInt(cursor.getColumnIndexOrThrow("_id")); 
    String amount = cursor.getString(cursor.getColumnIndexOrThrow("amount")); 
    String category = cursor.getString(cursor.getColumnIndexOrThrow("category")); 

    viewID.setText(String.valueOf(id)); 
    viewAmount.setText(amount); 
    viewCategory.setText(category); 

    buttonDelete.setOnClickListener(new View.OnClickListener() { 
     @Override 
      public void onClick(View v) { 
       Toast.makeText(context, "Deleted item " + id, Toast.LENGTH_SHORT).show(); 
      //Do I create a DB handler here and run a dbHandler.deleteItem(id) 
      //method or do something else?  

      } 
     }); 

    }

相同的代碼試圖表明這一個

buttonDelete.setOnClickListener(new View.OnClickListener() { 
    @Override 
     public void onClick(View v) { 
      Toast.makeText(context, "Deleted item " + id, Toast.LENGTH_SHORT).show(); 
      String query = "DELETE * from *table_name* where _id = "+ id + ""; 
      db.execQuery(query) // db is your DatabaseHelper 
      startActivity(getIntent()); 
      finish();     
     } 
    }); 

}
