I find that the problem why scrollToPosition, and others API, does not work is because the dataset is not yet ready. When to scroll RecyclerView to a certain position? The right question to ask about scrollToPosition is not How, but When. Try to reduce the delay, usually 500 milliseconds is enough. This is a bit hacky, but always works (in my scenario). Import 7.widget.Enter fullscreen mode Exit fullscreen mode Create the source code of the main AndroidRecyclerViewActivity ActivityĪdd a new Java class inside src// so that we are going to have the src//AndroidRecyclerViewActivity.java file and paste the code below.ĪndroidRecyclerViewActivity.java package We should have the /res/layout/main_activity.xml file and paste the code below.ģ. Now,we are going to make the layout of this Activity, which will be a simple layout xml for the AndroidRecyclerViewActivity.class, that consists of a LinearLayout with vertical orientation, that includes a RecyclerView.Īdd a new xml file inside /res/layout folder, with name main_activity.xml.
The AndroidRecyclerViewActivity is the main Activity of our example, and this is the Activity in which we are going to create a RecyclerView, set its RecyclerView.Adapter and its RecyclerView.LayoutManager. Create the layout of the main AndroidRecyclerViewActivity You can lear more in the Android developers’ documentation. We can find the RecyclerView class, in the v7 support library, and this gives us the opportunity of the backwards compatibility with Android versions prior to Lollipop. You can also set default animations for adding and removing items from the RecyclerView. One of these features, is that Android RecyclerView can help you position a bunch of items either horizontally, or vertically, generally, in whichever way you may want, as the RecyclerView can help you set a LayoutManager and define the layout mode of its items. However, there are also new features about Android RecyclerView. However, the Android Lollipop introduces a new and faster way to represent list layouts, with the use of Android RecyclerView.Īndroid RecyclerView is an improved version of Android ListView and has many common things and ideas, such as the ViewHolder pattern, which is a pattern that is used to store references to the views for each RecyclerView item. For years now, in Android, if you wanted to create an application that uses lists to display data, the most common, choice, would be the ListView solution.
