RecyclerViews are popular because of their flexibility and ease of use. Especially data coming from databases like sqlite and webservices qualify as good for being rendered in recyclerview. RecyclerView on the other hand is an adapterview that allows us render large datasets. ItвЂ™s also free and actively maintaied since itвЂ™s inception in the year 2000.

We are using this layout to inflate the records we are inserting. SQLite is another data storage available in Android where we can store data in the userвЂ™s device and can use it any time when required.In this article, we will take a look at creating an SQLite database in the Android app and adding data to that database in the Android app. When there are no contacts, we are showing the вЂњNo RecordsвЂќ and when user inserts the data, we hide that section. This layout holds all the records and an Add button to add records. We will need to create three layouts for our project And from that screen you can update the record.
