习惯用户中未更新字符串的图像将填充列表视图
我会尽力解释发生了什么，所以我的代码有一个forloop填充列表视图，这个listview显示json文件中的所有正确数据，图像的excpet，图像总是从最后位置在列表视图中，然后复制到上面的那个，例如
这是一个单一的活动，我只是为了使其适合而进行片段化。我猜它与我为创建图像而创建的字符串有关，它们以某种方式被使用了两次，然后再次用于填充列表视图，即使所有其他字符串都被重置并在其获取时被填充来自JSON的新信息。如果有人能告诉我为什么这只发生在图像而不是创建项目名称的字符串

1 个答案:
答案 0 :(得分：0)
所以我做错了是因为我只是使用了一个字符串，它只包含listview上最后一个条目的信息，因此为什么它只显示来自它的图像，所以为了解决这个问题，我必须将其更改为以下;
ItemNameInLowerCase = holder.champitem1.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName2InLowerCase = holder.champitem2.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName3InLowerCase = holder.champitem3.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName4InLowerCase = holder.champitem4.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName5InLowerCase = holder.champitem5.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName6InLowerCase = holder.champitem6.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemNameInLowerCaseHW = holder.champitem1HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName2InLowerCaseHW = holder.champitem2HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName3InLowerCaseHW = holder.champitem3HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName4InLowerCaseHW = holder.champitem4HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName5InLowerCaseHW = holder.champitem5HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
ItemName6InLowerCaseHW = holder.champitem6HW.getText().toString().toLowerCase().replaceAll("'", "").replaceAll(" ", "");
