android - 滚动视图高度

Question

我的布局包含页眉、滚动视图中的内容和页脚。页眉和页脚的位置应该是固定的，但是当我启动应用程序时，页脚是不可见的，我只能滚动到内容的底部，仅此而已。我怎样才能使它仍然可以向下滚动到内容的底部，但我的页脚始终可见？

Answer 1

您应该layout_weight为 ScrollView 使用 a ，这样它就不会占用所有剩余空间：

    <ScrollView
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1">

Answer 2

添加android:layout_weight到ScrollView
