android:layout_alignParentBottom在ListView中没有显式布局高度的情况下使用时被忽略 [英] android:layout_alignParentBottom is ignored when used without explicit layout height as a row in ListView
问题描述
当我使用RelativeLayout并将fill_parent或wrap_content作为高度，并指定一个元素:android:layout_alignParentBottom="true"时，它将被忽略，并在顶部对齐.将RelativeLayout的高度设置为显式值可以使其起作用.有任何线索吗?
When I use a RelativeLayout with either fill_parent or wrap_content as height and an element which specifies: android:layout_alignParentBottom="true" it is ignored and it is aligned at the top. Setting the height of the RelativeLayout to an explicit value makes it work. Any clues?
推荐答案
This seems to be a bug in Android itself, see http://code.google.com/p/android/issues/detail?id=1394.
我通过将RelativeLayout包裹在FrameLayout中并将底部对齐的视图作为FrameLayout的子级和android:layout_gravity="bottom"来解决此问题.这会阻止您从RelativeLayout内部引用它，因此您必须解决该问题(例如，使用边距).
I worked around it by wrapping my RelativeLayout in a FrameLayout and putting my bottom aligned view as a children of the FrameLayout with android:layout_gravity="bottom". This hinders you from referencing it from within the RelativeLayout so you'll have to work around that (for example using margins).
如果有人有更好的解决方法，请分享.
