How Do I Handle Layout Changes When Orientation Changes?

I am trying to simply alter the setlayout when I rotate my device so that I can have a layout of Views for a particular activity that is suited to the current orientation of the Android device but I am confused about the best way to achieve this.

I have referred to the following android doc:

Handling Runtime Changes

I do not n开发者_如何学JAVAeed to save any data from my Activity so don't think I really need to use the onRetainNonConfigurationInstance() method. I tried handling the orientation change myself through the onConfigurationChanged() method, where I find the current orientation then set the layout as required but this results in views that no longer work. Is there something else I need to do in onConfigurationchanged()?

Thanks

To get a different view for landscape as opposed to portrait, you would place your layout XML file in both of the following resource folders:

/res/layout - Portrait

/res/layout-land - Landscape

This is, of course, if you have the same views within both, otherwise you may get some NullPointerExceptions.

You can create a new directory under res called "res\layout-land", create an .xml layout file in both "res\layout" and "res\layout-land" that have the same name. For example: "myLayout.xml". Android will automatically use the layout from the -land directory when in landsacpe orientation and the other when in portrait.

in your projects res folder you should have a layout folder. Create a new folder in the res and call it layout-land. Now create your second set of layout.xml files that are specific to landscape oriented devices. Save them in this layout-land folder. The system will handle the rest for you.

check out this page and scroll down to "Providing Alernative Resources" for more detail about different qualifiers you can use on your res folders.

Edit: What device are you using? I created a quick test project that is nothing but hello world but displays different text from a layout stored in res/layout-land folder. I tried it once with and once without configChanges="orientation" in the manifest. When I run the app and switch orientations the layouts behave as expected. The layout from layout-land is displayed when device is landscape and layout from plain layout folder is shown when device is in portrait.

The device I tested on is Sidekick 4g. Download the test project and report back how it works on your device if you like.
