Elevate Your App's Aesthetic: Customize Android Status Bar Color with Kotlin in 3 Easy Steps

In Android development, creating visually appealing and cohesive user interfaces is essential for a positive user experience. One way to enhance the look and feel of your Android app is by customizing the Android status bar color. In this tutorial, we’ll explore how to programmatically change the status bar color using Kotlin.

Why Customize the Android Status Bar Color?

The status bar is the horizontal bar at the top of an Android device’s screen, displaying important information such as time, battery level, and notifications. By default, Android assigns a system-wide color to the status bar. However, customizing this color can help your app stand out, maintain brand consistency, and provide a more immersive user interface.

Step 1: Project Setup

Assuming you have an existing Android Studio project, open your MainActivity.kt file.

Step 2: Change the Status Bar Color Programmatically

Inside the onCreate method, where your main activity is initialized, add the following code snippet:

import android.os.Build
import android.os.Bundle
import android.view.Window
import android.view.WindowManager
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // Change the status bar color
        changeStatusBarColor("#3498db") // Replace with your desired color code
    }

    private fun changeStatusBarColor(color: String) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            val window: Window = window
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            window.statusBarColor = android.graphics.Color.parseColor(color)
        }
    }
}

Replace "#3498db" with the hexadecimal color code of your choice.

Step 3: Run Your App

Build and run your app to see the changes in action. The status bar at the top should now reflect the color you specified in the code.

Conclusion

Customizing the Android status bar color in Android apps can be a simple yet impactful way to enhance the overall aesthetic. Whether you’re aligning with your brand’s color scheme or creating a unique visual identity, taking control of the android status bar color adds a personal touch to your app.

In this tutorial, we’ve walked through the process of changing the status bar color programmatically using Kotlin. Experiment with different color codes to find the perfect match for your app’s design. Happy coding!
