The following gif is an overview of what we are about to build
First of all create a new project in android studio
now setup the following dependencies in your app level build.gradle file
Now setup all the assets like shown below
go to res >> drawable and create brown_border.xml,pedit.png,pdelete.png
brown_border.xml
Now go to res >> values >> colors.xml and add the following
Now go to res >> values >> strings.xml and add the following
Now create res >> menu >> menu_main.xml like this
Now create res >> layout and add the following
activity_main.xml add_contact_layout.xml contact_list_layout.xml
Now let us look into some java code
First of all create a helper class which extends SQLiteOpenHelper as shown below
SqliteDatabase.java
The above helper class provides methods to perform all the basic CRUD operations like add, update, delete etc.Now we should create a model class for the contacts object, it should be like
Contacts.java
Now we should create a recyclerview adapter for our recyclerview. It will include a Filter method which would be used to do search operations within our contacts list.
ContactAdapter.java
Below is the code for ContactViewHolder.java which is used in the above adapter class
Update your MainActivity.java file like shown below
With this, we have come to the end of this tutorial, now try running the app!
