Layout不设置背景色，图片设置为透明的PNG，应该是最简单快速的方法吧~

之前虽然发现 RelativeLayout 能够堆叠，但是没有去仔细看过API，这回稍微查了下，发现这样的解释：

请输入图片描述

经过试验，确实也是这样。

最外层用 FrameLayout ,底部为 LinearLayout ，底部背景设置成透明， layout_gravity 设置为 bottom

我比较喜欢的方式是：最外层用 RelativeLayout ,底部为 LinearLayout ， android:layout_alignParentBottom="true" background 设置为透明背景即可
