我希望我的编辑按钮始终显示在屏幕底部。以下是我的代码。

            </android.support.design.widget.TextInputLayout>
        </RelativeLayout>
    </ScrollView>

</RelativeLayout>

问题：问题是按钮没有显示在底部而是显示在屏幕顶部，而ScrollView根本看不到。如果我将外部RelativeLayout的android：layout_height =“match_parent”中的match_parent更改为某个值（如500dp），那么它可以正常工作，但只要我将其更改为match_parent，按钮就会显示在顶部。任何人都可以帮我找到需要纠正的地方吗？感谢

Answer 1

我把FrameLayout放在scrollView中。并且在片段的布局中我试图再次使用scrollView，因此，我正面临着这个问题。我通过删除framelayout的滚动视图来解决它

RelativeLayoutwith ScrollView和Button未在屏幕底部设置
