Overlay ActivityIndicator / Progress Bar / Loading Spinner in React Native

This is an Example of Overlay ActivityIndicator / Progress Bar / Loading Spinner in React Native. This is the most common thing that we use in every application. We will use the react-native-loading-spinner-overlay library to make an overlay Loader. This is basically used to block the screen while the application is doing some work like fetching data from the server or processing any big data which needs some resources.

To make an Overlay ActivityIndicator we will use Spinner component provided by react-native-loading-spinner-overlay.

Spinner

In this example, we will make an overlay Spinner which will be visible in every 3 seconds using an interval function. So Let’s get started.

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 Dependency

To use Spinner component you need to install react-native-loading-spinner-overlay dependency.

To install this open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module directory named react-native-loading-spinner-overlay.

–save is optional, it is just to update the react-native-loading-spinner-overlay dependancy in your package.json file.

Dependency Version for this Example Used is

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

App.js

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).

     

That was the example of Overlay ActivityIndicator/Progress Bar/Loading Spinner in React Native. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

Example to Show the Working of Slider in React Native

This is an Example to Show the Working of Slider in React Native. React Native Slider is a component to select a single value from a range of values. We have mostly seen slider while increasing or decreasing the volume or brightness of our phone. Here is the example of the slider which will be helpful for you to integrate slider in your app.

Under the Lean Core Project Slider has been moved to its new home @react-native-community/react-native-slider after the launch of React Native 0.59. If you are using React Native >= 0.59 then please follow the instruction for React Native >= 0.59.

This will make a project structure with an index file named App.js in your project directory.


Additional Step for React Native >= 0.59

as we are using @react-native-community/react-native-slider in React Native >= 0.59 then we have to install and link the dependency.

Installation of Dependency

To use Slider we need to install @react-native-community/react-native-slider dependency.

To install this open the terminal and jump into your project using

Run the following command to install

This command will copy all the dependency into your node_module directory.

–save is optional, it is just to update the @react-native-community/react-native-slider dependancy in your package.json file.

Linking of Dependency

After installing the dependency 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.


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

App.js

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).

That was the example to show the working of Slider in React Native. If you have any doubt or you want to share something about the topic you can comment below or contact us here. The remaining components will be covered in the next article. Stay tuned!
