Java 在listview中滚动时，选择会消失，并伴有奇怪的行为
我的listview遇到了一些奇怪的问题。我使用listview创建了一个列表，并使用一个自定义适配器显示带有文本字段和多个图像的行。我相信我的那部分工作得很好。我还将两个按钮放在listview的底部，以便选择行并使用这两个按钮修改它们。我通过简单地更改背景颜色，然后设置一个布尔标志来实现高亮显示，该标志是每行的一部分，这样我就可以知道高亮显示了哪些行。现在我遇到两个问题。第一种情况是，如果我选择一行，然后滚动，使该行在屏幕之外，那么该行将不突出显示，这是不好的。我只希望在用户再次单击某行或发出命令时，该行不高亮显示。第二个问题是，一旦适配器被更新或一行移出视图，如果您尝试单击一行，它将立即取消高亮显示；这种情况只发生一次。之后，您可以单击该行，它将保持高亮显示。我将非常感谢您的帮助。 问候 HelmetList.javaJava 在listview中滚动时，选择会消失，并伴有奇怪的行为,java,android,listview,android-arrayadapter,Java,Android,Listview,Android Arrayadapter,我的listview遇到了一些奇怪的问题。我使用listview创建了一个列表，并使用一个自定义适配器显示带有文本字段和多个图像的行。我相信我的那部分工作得很好。我还将两个按钮放在listview的底部，以便选择行并使用这两个按钮修改它们。我通过简单地更改背景颜色，然后设置一个布尔标志来实现高亮显示，该标志是每行的一部分，这样我就可以知道高亮显示了哪些行。现在我遇到两个问题。第一种情况是，如果我选择一行，然后滚动，使该行在屏幕之外，那么该行将不突出显示，这是不好的。我只希望在用户再次单击某行或发
