我正在为 android 开发简单的购物清单应用程序。因为我能够在列表视图中删除和取消删除项目。但是在打开关闭的应用程序后，我无法获得项目的更新（保存）删除线，所有项目都从删除线中清除

这是我为 onItemClickListener 实现的部分代码

    if (checkedVals[position]==true)
                      {                   
                          TextView text1 = (TextView)arg1.findViewById(R.id.customitemsrowTV);
                          text1.setPaintFlags(text1.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
                          text1.setTextColor(0xff000000);
                          String strikethrough1 = "false";
                          dbAdapterItems.updateItemsStrikethroughRecord(rowitemsid, strikethrough1);
                          //checkedVals[position] = false;
                      }
                      else
                      {
                          TextView text1 = (TextView)arg1.findViewById(R.id.customitemsrowTV);
                          text1.setPaintFlags(text1.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
                          text1.setTextColor(0xff888888);
                          String strikethrough1 = "true";
                          dbAdapterItems.updateItemsStrikethroughRecord(rowitemsid, strikethrough1);
                          //checkedVals[position] = true;
                      }

这是为列表视图填充的代码：

TextView itemsRowTv = (TextView)convertView.findViewById(R.id.customitemsrowTV);
            TextView quantityRowTv = (TextView)convertView.findViewById(R.id.customquantityrowTV);
            TextView priceRowTv = (TextView)convertView.findViewById(R.id.custompricerowTV);

            cItems.moveToPosition(position);
            String itemName = cItems.getString(1);
            checkedVals[position] = Boolean.parseBoolean(cItems.getString(3));
            String itemQuantity = cItems.getString(4);
            String itemPrice = cItems.getString(5);


             if (checkedVals[position]==true)
             {                   
                 itemsRowTv.setText(itemName);
                 //TextView text1 = (TextView)arg1.findViewById(R.id.customitemsrowTV);
                // itemsRowTv.setPaintFlags(itemsRowTv.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
                // itemsRowTv.setTextColor(0xff000000);
                // checkedVals[position] = false;
             }
             else
             {
                // TextView text1 = (TextView)arg1.findViewById(R.id.customitemsrowTV);
                 itemsRowTv.setText(itemName);
                 itemsRowTv.setPaintFlags(itemsRowTv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
                 itemsRowTv.setTextColor(0xff888888);
                // checkedVals[position] = true;
             }

请为我的问题提出解决方案...谢谢。

是的，在对 getView 块进行小幅编辑后，我得到了解决方案：就是这样，

 if (checkedVals[position]==true)
             {                   
                 itemsRowTv.setPaintFlags(itemsRowTv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
                 itemsRowTv.setTextColor(0xff888888);

             }
             else if(checkedVals[position]==false)
             {

                 itemsRowTv.setPaintFlags(itemsRowTv.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
                itemsRowTv.setTextColor(0xff000000);
             }
