我有一个布局,我希望最后一个LinearLayout
在最底部对齐。我试图设置重力和android:layout_marginbottom=0dp
,似乎没有人将它对齐到底部。

答案 0 :(得分:5)
您必须使用android:layout_gravity
来执行此操作,而不是android:gravity
。
http://developer.android.com/reference/android/widget/FrameLayout.html
layout_gravity
指定相对于父级的引力,gravity
控制内容在视图中的位置。

You should take a relative layout as inner layout of linear layout. Like this example. I hope its useful for you.
