我使用RelativeLayout和LinearLayout创建了一个简单的ScrollView，ScrollView在较新的设备上运行良好，我在Nexus 5上进行了测试，一切正常，但当我在较旧的设备（不太旧）上进行测试时，滚动不起作用，布局仅显示视图的顶部，不允许我进行滚动

我试图用线性布局包围我的布局，试图遵循stackoverflow用户建议的方法，但没有成功

有什么想法吗？

试试看。我不确定它会不会工作，因为我不知道你的百分比布局

滚动视图的子视图应设置为包装内容。如果将其设置为匹配父项，它将填充ScrollView的区域，并且永远不会滚动，因为它不会比ScrollView大

尝试将子LinearLayout布局高度更改为包裹内容或特定大小（以dp为单位），而不是匹配父项

编辑：

另外，尝试将滚动视图的高度从匹配父对象更改为换行内容。因为只有当滚动视图的总高度大于父视图的高度时，滚动视图才会启用滚动
