Place Holder can be anything like RelativeLayout with id, Linear Layout with id and Frame Layout with id. Instead of using fragment tag in Linear Layout, we have to use a PlaceHolder which can host a fragment, or we can say that we need a placeholder where the fragment will be added programmatically. Add a layout (placeholder) to the main XML that will host a Fragment. You can refer static method how to add those three stepsĤ. Set the layout file to the class which extends Fragment. Create a new Java class by extending Fragment.ģ.

To do that we will have to modify certain things, but still, the first three steps are same as we do in the static method.ġ.Create another layout XML file for fragment.Ģ. Instead of using XML file we will be using Activity. however, Fragments don't need to be registered in the manifest file because fragments exist when embedded in an activity.Īdding Fragment Dynamically to activity: Now we will see how to add a fragment to the activity dynamically. If the activity destroys then the fragments in it will also destroy. It is possible to create a Fragment that doesn't include UI but instead provide background behaviour for an activity.įragments can be added or remove to the activity while activity is runningĪ fragment is reusable.i.e., multiple Activities can use it.įragments have lifecycle methods similar to activitiesĪ fragment life cycle is closely related to the activity lifecycle in which they are being used. Like Activities, Fragments also have a separate layout by overriding onCreateView handler to inflate and return the required View hierarchy. To create a Fragment class, we need to create a new Extend Fragment class. We now see not just smartphones but other larger screens such as tablets and televisions that run in the Android platform. In this tutorial, we will learn about the basics of fragments and how they can be created.įragments: Fragments are added to the Android SDK at a crucial time when consumers were experiencing an explosion in the variety of Android devices coming to market.
