如何在Android中更改顶部布局？

Question

When I need to change an activity skin, can I change top layout while maintaining the activity?

like... change orientation of display.

For example,

I have 1 activity file,
MainActivity.java

and I have 2 layout xmls,
main_a.xml main_b.xml

My start activity is main_a.xml

In this situation, Can I change layout as main_b.xml programmatically?

Answer 1

Easy

setContentView(main_b.xml);

If you have 2 different layouts for portrait and landscape - it is even easier - just place landscape layout file into layout-land folder (not layout ) - and your layout will be applied automatically during orientation change
