Example of Searching in List using Search Bar in React Native

Example of Searching in List using Search Bar in React Native

Here is an Example of Searching in List using Search Bar in React Native. In our previous example of a search bar using TextInput, we have mentioned that searching is very important if we have a long list. It provides great user experience and control over the data to the App user. The user can easily search the data he/she requires using the search bar.

In this example of React Native Search Bar, we will make a search bar using a SearchBar component provided by react-native-elements.

The logic is simple

  • We will load the list from the network call and then show it to the user.
  • The user can search the data by entering the text in TextInput.
  • After inserting the text SearchFilterFunction will be called
  • We will compare the list data with the inserted data and will make a new data source.
  • We will update the data source attached with the ListView.
  • It will re-render the list and the user will be able to see the filtered data.

SearchBar Component

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run
npm install -g react-native-cli
Run the following commands to create a new React Native project
react-native init ProjectName
This will make a project structure with an index file named App.js in your project directory.

Installation of Dependencies

To use SearchBar we have to install react-native-elements and react-native-vector-icons dependencies.

For installation open the terminal and jump into your project using.

Run the following command.

This command will copy all the dependencies into your node_module directory, You can find the directories in node_module.

–save is optional, it is just to update the dependancies in your package.json file.

Linking of Dependencies

After installing the dependencies you need to link it with your project using

After linking the dependency if you face  Could not Compile Settings File project/android/settings.gradle error while building and installing the project then you can find the solution here.

Now Open App.js in any code editor and replace the code with the following code.


To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
