Android, landscape only orientation? - android

How can I make it so the screen orientation is always landscape?
Do I need to add something to the manifest.xml?

Add this android:screenOrientation="landscape" to your <activity> tag in the manifest for the specific activity that you want to be in landscape.
Edit:
To toggle the orientation from the Activity code, call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) other parameters can be found in the Android docs for ActivityInfo.

Yes, in AndroidManifest.xml, declare your Activity like so: <activity ... android:screenOrientation="landscape" .../>

Just two steps needed:
Apply setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); after setContentView().
In the AndroidMainfest.xml, put this statement <activity android:name=".YOURCLASSNAME" android:screenOrientation="landscape" />
Hope it helps and happy coding :)

One thing I've not found through the answers is that there are two possible landscape orientations, and I wanted to let both be available!
So android:screenOrientation="landscape" will lock your app only to one of the 2 possibilities, but if you want your app to be limited to both landscape orientations (for them whom is not clear, having device on portrait, one is rotating left and the other one rotating right) this is what is needed:
android:screenOrientation="sensorLandscape"

When you are in android studio 3 or above
you need to add following lines AndroidManifest.xml file
<activity
android:name=".MainActivity"
android:configChanges="orientation"
android:screenOrientation= "sensorLandscape"
tools:ignore="LockedOrientationActivity">
One thing this is sensor Landscape, means it will work on both landscape sides
But if you only want to work the regular landscape side then, replace sensorLandscape to landscape

You can try with
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Screen orientation changes when unlock the device

I have an application in landscape orientation. This is how the manifest looks like:
<activity
android:name="Activity"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:launchMode="singleTask"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden">
</activity>
When I lock and unlock the device the orientation changes to portrait for half of second and then goes to landscape. I noticed that this is not happening on all devices. I could reproduce it on Samsung Galaxy SI.
Any ideas what can it be?
Adding "orientation|screenSize" to configChanges does not fix the issue.
EDIT:
Basically, the layout is losing its orientation when I slide the unlock screen(specially on Samsung devices) because it's taking the orientation of the slide activity which is portrait.
Changing the name of the layout folder to "layout-land" may fix this by only allowing drawing in landscape
You need to add the below properties in the activity tag of manifest you want,,,rather than adding your application tag
<activity
android:name="com.example,MainActivity"
android:configChanges="keyboardHidden|orientation"
android:screenOrientation="landscape"
android:windowSoftInputMode="adjustPan" >
</activity>
Or if this do not work,,, then add this code just below the setContentView() in your Activity
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

How to keep my views from being redrawn

I have a simple app. And I would prefer the views stay the way they are when the orientation change. How can I do that?
Thanks in advance!
Add android:configChanges="keyboardHidden|orientation" to the activity in the manifest file..
<activity
android:name="..." android:configChanges="keyboardHidden|orientation">
</activity>
And read Handling Runtime Changes
In addition to #Nunu's answer you may wish to override onConfigurationChanged(...) to make any essential changes to your views.
You can also lock activities to portrait or landscape in the manifest.
EDIT
To lock in portrait declare your activity in the manifest like this:
<activity
android:name="com.yourpackage.YourActivity"
android:screenOrientation="portrait" />
you should check the sample application of "Multiresolution" in your android-sdk-windows /samples directory

How can we set in application run only vertically not horizontally? [duplicate]

You can specify in your activity in manifest.xml how you want it to work
e.g
<activity
android:screenOrientation="landscape"> //for landscape ie horizontal
and
<activity
android:screenOrientation="portrait"> //for portrait ie vertical
If you want to make your application in force portrait mode you can to do by adding this in the manifest file :
<activity android:name=".activityName" android:screenOrientation="portrait" />
Your question is too vague.
To use your application only vertically (portrait) mode, then following changes you have to do in manifest file
<activity android:name=".YourActivity" android:screenOrientation="portrait">
This will allow your activity to run in vertical mode (portrait mode) only and its activity configuration will not be changed even if you change device orientation.
You do this in the AndroidManifest.xml file on the activity. Take a look at the Activity element documentation.
<activity android:name=".MyCustomActivity"
android:screenOrientation="portrait"
[...]
Programmatically you can do this in your activity as follows:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

Landscape mode creating issues in app

I had an application of timer and my app should always be in landscape mode. In manifest, I had used:
<activity android:name=".MActivity"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.NoTitleBar"
android:configChanges="keyboardHidden|orientation">
But sometimes, when I switch from background to foreground, it first appears in portrait mode and then resizes to landscape mode. What's happening here?
Thanks in advance.
Do you have the same situation if you paste this line in every of your activities (in the onCreate):
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
use android:configChanges="keyboard|keyboardHidden" not the orientation for this attribute

Forcing 'portrait' orientation not working - any tips?

Hey all - I have tried to only display my app in portrait view orientation to no avail.
I have the code: android:screenOrientation="portrait" in every button, ImageView, TextView, etc... in my xml files but when I tilt the phone to the side, it still goes into landscape view.
I do call the camera in my app, but I don't think that is the issue - any thoughts?
the layout is the wrong place. you have to place it in the activity like this:
<activity android:screenOrientation="portrait" ...>
Force an Android activity to always use landscape mode
is google that hard to understand? google "android force portrait" and the first four links shows the answer... (sorry.. just had to let it out :) )
You have to put the android:screenOrientation="portrait" in the AndroidManifest.xml.
In AndroidManifest.xml you have to do something like this:
<activity android:name=".Your_Activity_Name"
android:configChanges="keyboardHidden|orientation"
android:screenOrientation="portrait"/>
