推荐答案

这正是一个线性布局应该是prevent。但是，您可能能够覆盖使用负填充下一个元素的定位。这样做的问题是不同的屏幕密度会发生什么。

This is exactly what a linear layout is supposed to prevent. You may however be able to override the positioning of the next element using negative padding. The problem with that is what happens on different screen densities.

我想这是从表面上看是为。它提供了一个透明的绘图表面整个屏幕让您在其他意见绘图。

I think this is what a surface view is meant for. It provides a transparent drawing surface over the entire screen allowing you to draw in top of other views.

最后一个想法是把你的第一个形象在你的线性布局内的框架布局。然后，你可以使用填充来定位它的叠加图像添加到框架布局。

One last idea would be to place your first image in a frame layout inside your linear layout. Then you could add your superimposed image to the frame layout using padding to position it.
