I developed an application in portrait mode in Android.
What changes do I have to do, that my application will be also fit for landscape orientation?
Thanks in advance.
Technically speaking, you don't HAVE to make any changes for it to fit to landscape. It you're using the standard wrap_content and fill_parent for your width and height, your layout will automatically adjust when you change orientations.
With that said, you will often WANT to change to a different layout when switching from portrait to landscape, as a layout that looks good vertically may be unusable when horizontal. You can add a new folder beside your /layout folder titled layout-land. In this, make a new XML file with the same title as your previous layout, and then change the layout from there. Be sure that any and all defined android:ids exist in both the original and landscape layout.
Make sure you use layout_width as "fill_parent" where ever required.

How do I change the orientation of a LinearLayout when a device changes orientation? What changes would be needed in the *.xml's associated *.kt file?
For example, the device is in Portrait and displays a LinearLayout with a vertical orientation. When the device turns and becomes Landscape, the LinearLayout should have a horizontal orientation.
I imagine that two different layouts would be called depending on the configuration change but I'm not sure.
You need to use separate folders for your layouts : layout for portrait mode and layout-land for landscape mode, and put two separate xml files with the same name in each one.
One of xml files with LinearLayout with a vertical orientation and another xml file with LinearLayout with horizontal orientation.
For instance look at How to Add/Create Landscape Layout in Android Studio
i'm working on an android app , trying to make it responsive in different screen sizes, so i'm using constraintlayout . But i had a problem when i test it in a tablet in mode portrait (vertical) there is so much space in the bottem i've tried to work with PercentRelativeLayout(supports percentage based margin and dimensions for Views) it has a good result but it's deprecated. Any idea please ?
You could also use ConstraintLayout Chaining to connect your Views into a group and then you can center, expand, pack these into the available space as desired. This layout will change dynamically based on the screen size and orientation.
Using alternate layouts as mentioned (layout-sw600dp) is also a good idea. The system will automatically use this layout instead of the default layout. 600dp is a good display width to make the breakpoint for tablets.
I have downloaded the google io application and I noticed that for landscape layout, its only the dashboard layout that have a landscape layout (in the layout-land folder).
My question is the following, is it for all the layout available in our project that we must create a landscape layout or it is only for the dashboard layout?
Thanks.
Kind Regards.
You are allowed to create a landscape layout for any layout in your app. You should do this when you want to have a different layout in portrait vs. landscape. Sounds to me like the Google IO app specifies a different landscape layout for only one screen (the home screen/dashboard), presumably because that's the only screen the developers felt needed a different landscape layout. Point is, it's up to you which screens have alternate layouts.
It depends on the data you have to show.
Sometimes there is more data which can be shown because of extra width in landscape and you have to compress data vertically in landscape. For such cases use different layouts
Can we fix the orientation for one imageview in framelayout, and orientation of other children of frame layout be controlled by the sensor?
I want to fix the orientation of image in background and on top of that need to show some reults in textviews. If I fix the activity in landscape then I can't draw the text portrait wise.
You can use separate xml for portrait and landscape mode.
1.you have to create separate folders layout-land, layout-port
2.save the xml in it.
3.Be sure with both have the same name.
You can refer here
Orientation can only be applied on activities,we cannot set the orientation of views.
I have a ViewFlipper with several ScrollViews inside. Depending on the child ScrollView I need to force the ViewFlipper's orientation to portrait or landscape. How can I achieve this ? Thanks.
Take a look at http://developer.android.com/guide/practices/screens_support.html and http://developer.android.com/reference/android/widget/HorizontalScrollView.html
In the first document, note that you can provide different layout files for landscape versus portrait modes. For example, for landscape mode, you could have a layout file in res/layout-land.
If you want more help putting the pieces together, just ask.
Edit: It looks like I misread the original question. Take a look at these two posts:
Force an Android activity to always use landscape mode
Android force Horizontal (landscape) layout
