Android Screen Orientation size - android

I have created various layout resource files in order to ensure that my app supports all screen and devices sizes.
My problem is which one of the below is suitable to use in my AndroidManifest file. Once the user switches the device to landscape I would like Android to choose the landscape resource file instead of portrait.
android:configChanges="screenSize|keyboardHidden"
android:configChanges="orientation"
Which one is more suitable to use?.

You just create One extra folder in your res folder named layout-land and put all landscape layouts in this folder then operating system automatic show the layouts according device orientation.
No need to add anything Manifest File.

Android system does it automatically. You don't need to put anything in your manifest.

Android manually select layout folder

In Android is it possible to select layout directory programmatically (in my case select the layout-land layout when I request)?
The reason I am asking is that in my application I am having hard time adopting it do various screen proportions, and the default Android logic of picking the layout file from layout-land or from layout does not work for me. It would be much better if I could manually decide which proportion is considered landscape. And I do not want to fix the screen orientation.
You can force your activities to be always in a landscape mode see here
<activity
...
android:screenOrientation="landscape"
...
/>
but note that
If your application targets Android 3.2 (API level 13) or higher, then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.
And you can set the same data in your code as well.
myActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

No, sorry.

Then use other resource set qualifiers, such as -wNNNdp (use these layouts for devices whose current width is NNN dp or larger) or -swNNNdp (use these layouts for devices whose smallest width, in any orientation, is NNN dp or larger).
If none of those suffice, you will need to have distinct layout resources (e.g., activity_main.xml and activity_main_other.xml), and request those yourself based on your own criteria.

Android Default layout

so I have this folders with corresponding xml
layout-sw200dp
layout-sw600dp
layout-sw600dp-land
layout-sw800dp
layout
my problem is the layout folder automatically detects android wear on device selection preview. I don't want to use my app for android wear How can i remove it? If I change it to another let say Nexus 5 preview I'll be redirect to sw600dp. I want my layout folder to use like a normal handset let say nexus one
If you don't want your layout to be different on different devices, you can just delete all layout-* folders, leaving only the layout folder.
Delete
layout-sw200dp
layout-sw600dp
layout-sw600dp-land
layout-sw800dp
And keep only layout directory
if you want to disable the screen support then u can do it by using
<supports-screens android:anyDensity="false"
android:largeScreens="false"/>
and more...by just mentioning it in your AndroidManifest file

Different layout for orientation AND screen size - Android

I know you can specify a different layout file for orientation by creating a directory;
layout-land
And I know you can create another layout file for a large(tablet) screen size by creating a directory;
layout-large
My question is, can you create a directory that supports both? Something like;
layout-land-large
It's vital for a piece of work that a certain screen layout is displayed only on a tablet device in landscape mode, otherwise it's the default. If my solution isn't valid, is there another way to do this?
Thanks.
Change the folder name to: layout-large-land

How to handle size and position of controls in Android's Activity for portrait and landscape orientation?

I want to desing a GUI for android's tablet. By default i want to use landscape orientation of this application, so i placed the controls (text boxes, text views etc) accordingly, but when i change the orientation of tablet from landscape to portrait, whole GUI of activity gets distrubed. Can anybody guide/help me what is the best approach for designing of GUI in android such that controls appearance should remain correct in either orientation (portrait or landscape)? Thanks in advance.
You have to create another folder in the res directory called "layout-land". Put the layout file for landscape in this folder and the one for protrait mode in the normal "layout" folder. Both files must have the same name. Android will automatically chose the correct layout depending of the current orientation of the device.
Check the link below, it will provide all information about how to design an application to support multiple screens with different sizes and resolutions.

How do I specify different layouts for portrait and landscape orientations?

I've seen references to being able to specify two separate layout xml files for an activity, one for Portrait and one for Landscape. I've not been to find any information on how to do that though. How do I specify for each activity which xml file is it's portrait layout and which is the Landscape layout?
Is it also possible to specify different layouts for different screen sizes? If so, how is this done?
Create a layout-land directory and put the landscape version of your layout XML file in that directory.
You just have to put it under separate folders with different names depending on orientation and resolution, the device will automatically select the right one for its screen settings
More info here:
http://developer.android.com/guide/practices/screens_support.html
under "Resource directory qualifiers for screen size and density"
For Mouse lovers! I say right click on resources folder and Add new resource file, and from Available qualifiers select the orientation :
But still you can do it manually by say, adding the sub-folder "layout-land" to
"Your-Project-Directory\app\src\main\res"
since then any layout.xml file under this sub-folder will only work for landscape mode automatically.
Use "layout-port" for portrait mode.
Just a reminder:
Remove orientation from android:configChanges attribute for the activity in your manifest xml file if you defined it:
android:configChanges="orientation|screenLayout|screenSize"
Fastest way for Android Studio 3.x.x and Android Studio 4.x.x
1.Go to the design tab of the activity layout
2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation
Update: On newer versions the options have been moved to the context menu of the .xml filename button. (Big thanks to Oliver Hoffmann for pointing that out).
I think the easiest way in the latest Android versions is by going to Design mode of an XML (not Text).
Then from the menu, select option - Create Landscape Variation.
This will create a landscape xml without any hassle in a few seconds. The latest Android Studio version allows you to create a landscape view right away.
I hope this works for you.
Create a new directory layout-land, then create xml file with same name in layout-land as it was layout directory and align there your content for Landscape mode.
Note that id of content in both xml is same.
The last line below is an example for applying two quantifiers: landscape and smallest width(600dp) screen. Update 600dp with the ones you need.
res/layout/main_activity.xml # For handsets
res/layout-land/main_activity.xml # For handsets in landscape
res/layout-sw600dp/main_activity.xml # For 7” tablets
res/layout-sw600dp-land/main_activity.xml # For 7” tablets in landscape
The above applies to dimens as well
res/values/dimens.xml # For handsets
res/values-land/dimens.xml # For handsets in landscape
res/values-sw600dp/dimens.xml # For 7” tablets
res/values-sw600dp-land/dimens.xml # For 7” tablets in landscape

Or use this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:scrollbars="vertical"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- Add your UI elements inside the inner most linear layout -->
</LinearLayout>
</ScrollView>
Right click res folder,
New -> Android Resource File
in Available qualifiers, select Orientation,
add to Chosen qualifier
in Screen orientation, select Landscape
Press OK
Using Android Studio 3.4.1, it no longer creates layout-land folder. It will create a folder and put two layout files together.
In Android Studio Chipmunk, the options you are looking for are here.
For landscape, the option is "Create Landscape Qualifier" in the XML name drop-down.
For different screen sizes, the option is "Create Tablet Qualifier"
these have been moved from previous Android Studio versions.
