resource\/layout folder<\/h2>\n
This is the preferred way of managing the layouts. By convention, Android expects landscape specific layout file in Sometimes we may need to restrict the layout to specific orientation. For example, if you are displaying a list of items, then you would prefer to display in portrait mode because here more number of list items can be displayed as compared to landscape mode. You can restrict the activity layout to the portrait mode with the help of Create a project, give an appropriate project and package name for this project. In the main layout file add three buttons. These three buttons will launch different Activities and these Activities handle layout in a specific way. Attach Define the Create a layout file named Now create another layout file with the same name( Create another class called Now, create the landscape and portrait layout files which will be selected and populated programmatically. In this part, we are going to detect the orientation of the phone and manually set the appropriate layout. As you can notice, I have named the layout files as Now define the We are going to restrict the orientation of the Activity below in landscape mode by defining this attribute Define the After adding the three Activities in it, the AndroidManifest.xml file should look similar to the one given below:<\/p>\n Once you are done with coding, just execute the project and you will see the application as shown below. Please feel free to leave comments about post or website.Thanks Sometimes the same layout doesn\u2019t scale well for both the orientations i.e landscape and portrait. It\u2019s always suggested to have different layout file for different screen orientation. Managing two layout for different orientations is quite easy. You can manage in two different ways. By using resource\/layout folder. By dynamically set the layout. resource\/layout folder This […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-36","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/code4reference.com\/index.php?rest_route=\/wp\/v2\/posts\/36","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/code4reference.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/code4reference.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/code4reference.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/code4reference.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=36"}],"version-history":[{"count":0,"href":"https:\/\/code4reference.com\/index.php?rest_route=\/wp\/v2\/posts\/36\/revisions"}],"wp:attachment":[{"href":"https:\/\/code4reference.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=36"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/code4reference.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=36"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/code4reference.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=36"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}res\/layout-land<\/code> and portrait layout file in res\/layout-port<\/code>.<\/p>\nDynamically set the layout<\/h2>\n
Configuration<\/code> class helps to determine the current orientation. Configuration<\/code> class object is being passed as an argument in onConfigurationChanged<\/code> method. This method is a callback method and gets called whenever there is change in configuration specified in the Activity attribute in AndroidManifest.xml file. This android:configChanges<\/code> attribute should be set to orientation<\/code> in the Manifest file. If you don\u2019t include this attribute in Android Manifest file, then the onConfigurationChanged<\/code> will not get invoked when there is change in the orientation.<\/p>\nRestricted layout<\/h2>\n
android:screenOrientation<\/code> attribute. You can notice this attribute in the AndroidManifest.xml file below. This attribute android:screenOrientation=\"landscape\"<\/code> of activity will restrict the activity in landscape mode whereas android:screenOrientation=\"portrait\"<\/code> will restrict the activity in Portrait mode. When you define this attribute in the AndroidManifest file, make sure to put the xml layout file in res\/layout<\/code> folder.<\/p>\nSource code<\/h3>\n
