 android kotlin change background color programmatically

Introduction:

Popular programming language Kotlin is frequently employed in the creation of android applications. The ability to alter the background colour of buttons in an Android application is one of its key features. We will go into great detail in this tutorial on how to modify the background colour of buttons in Kotlin Android.

Understanding Button Background Color:

The colour of the button background plays a significant role in the overall aesthetic appeal and user experience of any android application. Any Android application must include buttons because they are used to start actions when clicked. There are several ways to modify the background colour of buttons in Kotlin Android applications, and doing so can further personalise the software.

Setting Button Background Color:

There are two ways to set the background color of a button in Kotlin Android. The first way is to use the XML layout file and set the background color property directly. The second way is to use the Kotlin code and set the background color programmatically.

Method 1: XML Layout File

In this method, we will set the background color property directly in the XML layout file. This can be done by using the following code snippet:

<Button

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:background="#FF0000" />

In the above code snippet, the android:background property is used to set the background color of the button. The color code "#FF0000" represents the color red.

Method 2: Kotlin Code

In this method, we will set the background color programmatically using Kotlin code. This can be done by using the following code snippet:

button.setBackgroundColor(Color.parseColor("#FF0000"))

In the above code snippet, the setBackgroundColor function is used to set the background color of the button. The Color.parseColor function is used to parse the color code and convert it into an integer value that can be used as the background color of the button.

Conclusion:

The procedure for altering the background colour of buttons in Kotlin Android has been explained in this post. Your Android application can be further customised by altering the background colour of buttons, whether manually using Kotlin code or programmatically through the XML layout file. As a result, it can improve the application's overall aesthetic appeal and user experience.
