inflate包含gone布局的Layout 性能是比较差的

Conclusion

So, to conclude about this, inflating a layout with some views with a visibility set to GONE is bad for performances, especially if the view is a bit complex. If you don’t want to show this view verry often, I would suggest you to create a separate xml file containing your view, inflating this layout when needed, and adding it to your main layout programmatically.
