ScrollView问题：子布局无法适配父容器

在scrollview下加入的组件无论如何也不能自动扩展到屏幕高度,最后在这里找到解决办法，给ScrollView设置一个属性就可以解决了。

Found the solution myself in the end. The problem was not with the LinearLayout,  but with the ScrollView(seems weird, considering the fact that the ScrollView was expanding, while the LinearLayout wasn't).

The solution was to use android:fillViewport="true" on the ScrollView

android:fillViewport="true"
