Implement Different Types of AlertBox using Alerter Library in Android

In this article, we are going to implement a very important feature related to the AlertBox. Usually, we create an AlertBox to show some important content. Here we are going to learn how to implement that feature in our Android App using Alert Library. 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: Add dependency and JitPack Repository

Navigate to the Gradle Scripts > build.gradle(Module:app) and add the below dependency in the dependencies section.   

implementation ‘com.tapadoo.android:alerter:2.0.4’

Add the JitPack repository to your build file. Add it to your root build.gradle at the end of repositories inside the allprojects{ } section.

allprojects {

 repositories {

   …

   maven { url “https://jitpack.io” }

     }

}

After adding this dependency sync your project and now we will move towards its implementation.  

Step 3: 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. 

XML

Step 4: 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.
