Android App Background Image

In this article we will show you the solution of android app background image, any application can be made more beautiful by using background images.

As a result, the majority of social media platforms, like WhatsApp and Messenger, offer this to their users as a feature.

In light of this, we'll be creating an Android application that allows users to change the background image simply by hitting a button. Consider creating a background for an activity.

Building a straightforward application will involve showing a button and changing the background images of the application by leveraging the button's click event.

With the Random class, we will randomly retrieve images from a drawable folder.

So let's move on to the implementation without spending any more time. Below is a sample GIF that will help you understand what this post will cover.

You must use a beautiful wallpaper or image as the background if you want your UI (user interface) to be appealing.

When the background image you use does not have the same aspect ratio as the device it is running on, it gets stretched or compressed, compromising the background's appearance.

Furthermore, ImageView provides an alpha value for the background which is another advantage.

They determine the transparency/opacity of the background, with 1 equaling full visibility and 0 equaling full transparency.

You can also set a small value for alpha, like 0.28, if you think your text doesn't seem to be clear because it is the same color as the background.

It will be possible to create a simple application in which a button appears upon clicking its event.

The background images in the application we will make will be changed in this application.

The Random class will be used to access images randomly from the array of images saved in the drawable folder.

In this project, we intend to use Java as a programming language. Let's move on to implementation without wasting any more time.

Step By Step Guide On Android App Background Image :-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
                        android:layout_width="fill_parent"
                         android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
 android:background="@drawable/icon">
</LinearLayout>
  1. The first method accomplishes the task quickly, but it is not the most efficient method.
  2. Simply add the following code to your activity's layout XML file to get started.
  3. You can create a backdrop using any image saved in your app's drawable folder, where the background is the name of the image. android:background="@drawable/background"
  4. Make sure your app's drawable folder contains the background image you want to use.
  5. Put the following code in the parent layout of your activity's XML layout: Use android:background=@drawable/background instead of android:background=@drawable/background where the background is the name of the image in your app's drawable folder that you wish to use as the background.
  6. The background has been modified!

Conclusion :-

Background images play an instrumental role in the beautification of any application.

Hence, most social media applications like WhatsApp, and Messenger provide this as a part of their feature to their users.

So, keeping this in mind we will be planning to develop an Android application in which background images will get changed by button clicking.

I hope this article on android app background image helps you and the steps and method mentioned above are easy to follow and implement.
