Many apps represent data in the form of huge lists and for filtering these lists we have seen the SearchView present inside these apps. So for filtering this list of data we generally use a SearchView. In this article, we will take a look at the implementation of Search View in Android with a RecyclerView in Android.
What we are going to build in this article?
We will be building a simple application in which we will display a list of data in the RecyclerView. We will be displaying the list of courses with its description and on that recycler view, we will add a SearchView which will be used to filter the data in our Recycler View. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Working with the activity_main.xml file
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
Step 3: Creating a modal class for storing our data
Navigate to the app > java > your app’s package name > Right-click on it > New > Java class and name your class as CourseModal and add the below code to it.
Step 4: Creating a layout file for our item of RecyclerView
Navigate to the app > res > layout > Right-click on it > New > layout resource file and name your layout as course_rv_item and add the below code to it.
Step 5: Creating an adapter class for setting data to items of our RecyclerView
Navigate to the app > java > your app’s package name > Right-click on it > New > Java class and name it as CourseAdapter and add the below code to it.
Step 6: Creating a menu file for our SearchView
Navigate to the app > res > Right-click on it > New > Directory and give a name to your directory as the menu. After creating a new directory we have to create a new menu file inside it. For creating a new menu file. Navigate to the app > res > menu > Right-click on it > New > menu resource file, name it as search_menu and add the below code to it.
Step 7: Working with the MainActivity.java file
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
Now run your app and see the output of the app.
