+
+Android apps often populate the UI using
+:android:`RecyclerView <reference/androidx/recyclerview/widget/RecyclerView.html>`
+or :android:`ListView <reference/android/widget/ListView>` components.
+Realm offers **adapters** to display realm object 
+:ref:`collections <java-client-collections>`. These collections implement 
+the ``OrderedRealmCollections`` interface. :ref:`RealmResults <java-results-collections>`
+and :ref:`RealmList <java-list-collections>` are examples of these adaptors. 
+With these adapters, UI components update when your app changes 
+Realm objects.
+
+Install Adapters
+----------------
+
+Add these dependencies to your application level ``build.gradle`` file:
+
+.. code-block:: gradle
+   :copyable: false
+
+   dependencies {
+      implementation 'io.realm:android-adapters:4.0.0'
+      implementation 'androidx.recyclerview:recyclerview:1.1.0'
+   }
+
+Realm hosts these adapters on the
+`JCenter <https://mvnrepository.com/repos/jcenter>`_
+artifact repository. To use ``jcenter`` in your Android app, add it to your 
+project-level ``build.gradle`` file:
+
+.. code-block:: gradle
+   :emphasize-lines: 3, 9
+   :copyable: false
+
+   buildscript {
+       repositories {
+           jcenter()
+       }
+   }
+
+   allprojects {
+       repositories {
+           jcenter()
+       }
+   }
+
+.. seealso::
+
+   Source code: :github:`realm/realm-android-adapters` on GitHub.
+
+.. _java-adapters-model-item:
+
+Example Models
+--------------
+
+The examples on this page use a Realm object named ``Item``. 
+This class contains a string named "name" and an identifier number named 
+"id":
+
+.. tabs-realm-languages::
+
+   .. tab::
+      :tabid: java
+
+      .. literalinclude:: /examples/generated/java/local/JavaItem.snippet.complete.java

+
+.. _java-adapters-listview:
+
+Display Collections in a ListView
+---------------------------------
+
+Display Realm objects in a
+:android:`ListView <reference/android/widget/ListView>` by extending
+:github:`RealmBaseAdapter
+<realm/realm-android-adapters/blob/master/adapters/src/main/java/io/realm/RealmBaseAdapter.java>`.
+The adapter uses the ``ListAdapter`` interface. Implementation works
+like any ``ListAdapter``. This provides support for automatically-updating 
+Realm objects.
+
+Subclass ``RealmBaseAdapter`` to display
+:ref:`Item <java-adapters-model-item>` objects in a ``ListView``:
+
+.. tabs-realm-languages::

+         :language: java
+         :copyable: false
+
+      To display list data in an activity, instantiate a ``ListView``. Then, 
+      attach an ``ExampleListAdapter``:
+
+      .. literalinclude:: /examples/generated/java/local/AdapterTest.snippet.list-adapter.java
+         :language: java
