I am trying to add sliding drawer with scroll view but sliding drawer not working in scroll view, application collapse immediately showing error that scroll view can host only one child, i was unable to find out where is the error exactly and where to put sliding drawer in scroll view
please help me to resolve this issue
下面是我的android_main.xml代码，其中我将滚动视图作为所有元素的父容器，我无法在滚动视图中猜出滑动抽屉的确切位置，请帮我解决此问题。
提前谢谢
