Custom Progress Bar in Android using Kotlin.

This example demonstrates how to create a custom Progress Bar in Android using Kotlin.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

Step 3 − Add the following code to src/MainActivity.kt

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.ProgressBar
class MainActivity : AppCompatActivity() {
   lateinit var progressBar:ProgressBar
   override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)
      title = "KotlinApp"
      progressBar = findViewById(R.id.progressBar)
      progressBar.max = 100
      progressBar.progress = 20
   }
}

Step 4 − Add the following code to androidManifest.xml

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon  from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen.
