I want to change the background image of a button when clicked or focused.
This is my code:
A Button is a Push-button which can be pressed, or clicked, by the user to perform an action. Following are the important attributes related to Button control. You can check Android official documentation for complete list of attributes and related methods which you can use to change these. Even though most phones don't have Oreo yet, Google has released Android 9.0 Pie. It's available on Google's own Pixel devices, and updates should soon be available to partnered devices from Essential, Nokia, Oppo, Sony, Vivo, and Xiaomi. We're already digging into it to highlight all of the features and changes.
Is this code right? Does it calls a button on its event?

you can implement in a xml file for this as follows:
now save this xml file in drawable folder and name it suppos abc.xml and set it as follows
Hope it will help you. :)
Its very easy to implement . For that you need to create a one xml file(selector file) and put it in drawable folder in res. After that set xml file in button's background in your layout file.
button_background_selector.xml
Now set the above file in button's background.
Sorry this is wrong.
For changing background color/image based on the particular event(focus, press, normal), you need to define a button selector file and implement it as background for button.
For example: button_selector.xml (define this file inside the drawable folder)
And apply it as:
use this codecreate xml file in drawable folder name:button
and in button xml file
To change the button background we can follow 2 methods
In the button OnClick, just add this code:
2.Create button_background.xml in the drawable folder.(using xml)
res -> drawable -> button_background.xml
Now set the above file in button's background file.
2nd method is better for setting the background fd button
You just need to set background and give previous.xml file in background of button in your layout file.
and done.Edit Following is previous.xml file in drawable directory
You can also create shapes directly inside the item
tag, in case you want to add some more details to your view, like this:
Beware that Android will cycle through the items from top to bottom, therefore, you must place the item
without condition on the bottom of the list (so it acts like a default/fallback).
- Create a file in drawable play_pause.xml
- In xml file add this below code
- In java file add this below code
and also add this

Ways To Change App Icon On Android
There are two ways in which you can change Android icons. The first method is to use a launcher while the second one is to use a standalone icon pack. Both of these methods do not require your phone to be rooted.
Method 1: Using a Launcher
There are quite a few launchers available on the Play store which you can choose from. Check the ratings and look for feedback to make sure you pick a launcher that works well and is suitable for your device. Once you pick the launcher you want to use on your phone, simply download and install the launcher.
After the launcher is installed, you will automatically be asked if you would like to start using the launcher when you press the home button. Choose the launcher as the default, and depending on the launcher you are using, you may be prompted with further steps to customize your screens.
Users who have been using a launcher before as well will be able to import the settings of their previous launcher, or else, you may need to spend some time to bring the different widgets and apps you use to your home screen.
Some launchers like Nova Launcher will even allow you to pick an image from your gallery for your app icon. With such amazing levels of flexibility in changing the app icons, you can continually assign your apps new icons either from images from your gallery or by using different launchers.
Launchers bring with them a spectrum of wallpapers, themes and app icons which can dress up your device the way you want it to be. Some of them may contain ads but they work well especially if you are a person who enjoys exploring variety when it comes to the way their phone looks.
Method 2: Using an App
Some of our readers do not find themselves to be comfortable using a launcher. But they do not mind changing the app icons to give their phones a fresh new look. In a situation like this, an app is a good way to change the app icons without changing the skin of your phone by using a launcher. Apps like Awesome Icons and Icon Changer are known to be user-friendly apps which can help you in changing Android icons.
Depending on the app, the steps for using it will vary. But for most of the apps that help in changing app icons, once the app is downloaded and installed, you must click on the app to open it and then choose the apps for which you want to change the icons. Some apps may even allow you to rename the app. This can be a fun way of giving your phone a new look.
It can also help in keeping prying eyes away from your phone, especially when you rename your banking apps or if you happen to be using adult apps, you can rename the app and change the icon and it is easier to use your phone without others knowing which apps are installed on your device.
Conclusion
Use these two methods to customize app icons so that you can give your phone a new look. Not only does it make Android interesting, it also ensures that you do not get tired looking at the same set of app icons on your phone. You can change the icon on your device as often as you like with these methods. Both of these methods can be used on phones without the need to root your device or by having a deep technical know-how of smartphones.
