Android Layout Folders: Layout, Layout-Port, Layout-Land

Android layout folders: layout, layout-port, layout-land

If you are in landscape or portrait Android looks for the layout file in either the -port or -land directory first, if it's not found then it falls back to the default layout directory.

You can read about providing alternative resources here. There are many more options than just land and port.

How to use layout and layout(land) xml files correctly?

You are preventing the activity from reloading by specifying android:configChanges in the manifest.

Removing this will allow the activity to reload on rotation change and therefore handle the layout correctly. You will then need to handle the life cycle events of the activity to save and restore transient data during the rotation.

Could a layout exist only in layout-land folder?

Hi please have a read

layout: it is all about general layouts

layout-port: it is all about a layout for widget that must change for portrait orientation

layout-land: it is all about alayout for widget that must change for landscape orientation

If in any case if you are in a landscape/portrait mode. Android firstly looks for the layout file in either the -portrait or -landscape directory first respectively, if it's not found then it will be back to the default layout directory to look.

There is no need to put layouts in layout-land folder if you know that you will be be using the landscape mode only. Use the default layout folder simply

what you can do is in yours case is

You can set the default orientation in your androidmanifest.xml

<activity android:name=".YoursActivity" android:screenOrientation="landscape" "/>

by means you can write and go for

<activity
        android:name=".YoursActivity"
        android:label="@string/app_name" 
        android:screenOrientation="landscapre" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Android Studio - layout-land folder not appearing

That's the slightly confusing 'android' view of Android Studio. It shows only one layout folder (also shows only one drawable folder) which really contains all folders. Switch the view to 'project' and you'll see all folders.

Layout landscape mode and Categories of layout folders

By default, the layouts in /res/layout are applied to both portrait and landscape device screeens.

For example you have main.xml

/res/layout/main.xml

you just need to add a new folder /res/layout-land, copy main.xml into it and make the needed adjustments, and so on for all of your layout files.

You just need to have same files for land and portrait but with different folders and of course with different modifications.

Hope this to help!

The layout layout in layout has no declaration in the base layout folder [error]

I had copied the xml files in the folder using Windows Explorer. It seems to have caused an encoding issue.
After deleting the files and coping them inside Android Studio, the problem was resolved.

How to create layout-small-land folder?

layout-small-land and layout-small-port are the correct answers, and they compile just fine for me. Perhaps there is something else amiss in your directory structure.

How to use fragment_main.xml in layout-land folder?
