I have layouts for portrait mode (in folder layout) and for landscape one (in the folder layout-land). This screen is located under one of the tabs, so I had to handle screen rotating (after screen has been rotated, no default screen restart occurs).
I would like to update view from 'layout-land' when screen rotates to landscape mode and from 'layout' when screen rotates to portrait one.
How can I do this?
You can use onConfigchange method in that setContentView(R.layout.name) this way will work.

Right now I have two different layout files, one for Large and one for large-land. Both are using constraint layouts. However whenever the tablet switches from portrait to landscape mode, the landscape mode layout displays correctly. But after switching back to portrait and back to landscape mode, the landscape layout no longer displays correctly. The right side of the layout seems to have extended past the actual screen.
To simplify,
Portrait -> Landscape: Landscape displays correctly
Portrait -> Landscape -> Portrait -> Landscape: Landscape layout breaks and extends past the screen for some reason.
Any idea why this may be happening? Thanks in advance!
I am developing an android application that supports multi-windows feature on Android 7.0.
I followed this guide on https://developer.android.com.
, imported sample project https://github.com/googlesamples/android-MultiWindowPlayground
I create a new resource named layout-land and did some testing. I recognized that landscape layout is inflated even though the device is in portrait mode.
Check out attached images.
How can I set portrait layout when device is in portrait mode.
Assume you have two screens. One is in landscape and one in portrait.
How can you say which one is in landscape and which one in portrait?
In portrait width of the screen is less than height.
And for landscape width of the screen is greater than height.
Agree?
So, here, when you enter multiwindow mode your app's window no longer fits screen - width is greater than height and it is considered as landscape.
That is why landscape layout resource is used.
There is no separate modifier for layout resource to be used in split-screen mode.
The only thing you can do to achieve portrait in your case is to remove layout-land.
Or you can create two separate layouts (without any modifiers such as -land) and in activity call activity.isInMultiWindowMode(); to choose corresponding layout you want to use.
i have two layouts here one is portrait and one is landscape the landscape is located in the layout-land folder and the the portrait is located in the layout folder both have the same name. what i want to do here is that when the emulator screen is portrait it will load portrait and when the screen is landscape it will load a landscape layout but it is not happening when the first view is portrait and when i change orientation it still loads the portrait layout in landscape view and when its landscape first and i change orientation to portrait it loads the landscape layout on portrait screen what seems to be the problem here.

Remove android:configChanges="orientation" in your AndroidManifest.xml section for this particular Activity.
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.
Supporting multiple screens
i want to have two buttons with vertical orientation when the device is in portrait mode,and in horizontal orientation when it is in landscape.How will i get it with only an .xml file?May i use something like "styles.xml" and say that if i have portrait do this and if i have landscape do the other one?Thanks
The layouts in /res/layout are applied to both portrait and landscape.
To use a different layout in landscape, create a folder /res/layout-land and create another xml file here with the same name. Android will automatically choose the layout corresponding to the current screen orientation.
EDIT :
If you cannot create a second folder or are concerned about performances, then you can override the onConfigurationChanged() method, as explained here.
