        <ScrollView

            android:scrollbars="none">

如果我从xml中删除背景图像，这也适用于nexus 4。我该如何解决这个问题？提前致谢

Answer 1

您可能已将图片放入 drawable-v21 文件夹中，该文件夹指的是Api 21级及以上。这些文件夹特定于 Lolipop 和发布Lolipop 版本。这就是为什么它不在Kitkat或更低版本中工作的原因。将您的图像放在 drawable 文件夹中，以便所有api版本都可以访问它。很高兴帮忙......

Answer 2

只需将图像放入drawable文件夹即可。 drawable -v21适用于Android版本＆gt; 19。因为如果这在android 4.4（api 19）中，它无法获取图像，而且可能会抛出错误

由于背景图片
