how to access layout-large layout in the activity?

I am having layout which I want to render on to different sizes of mobile (like WVGA854). Resource structure is like

res\layout\main.xml res\layout-large\main.xml

By default it is taking layout main.xml file itself of layout. Its 开发者_JAVA百科not pointing to layout-large\main.xml

its throwing exception:Activity can not start resource not found

So can any one guide me how can I acheive this and how to support mutiple screens with different layouts like large,small and default along with images specified in respective dip folders.

Thanks in advance

If your files are what you say they are, you should not get this error for main.xml. You have a main.xml in the res/layout/ directory, so that will be used if nothing better is found. I suspect your error may be related to some other resource.

Here are some sample projects from one of my books that demonstrate using multiple screen sizes and densities.
