Another method to change the button color in Android Studio is by using Java code. This method provides greater flexibility and allows you to change the button color dynamically at runtime. Here are the steps to change the button color via Java code:
Step 1: Open the Java file corresponding to the activity where the button is located. It is usually named "MainActivity.java" or similar.
Step 2: Declare a button object and initialize it with the corresponding button from the XML layout file. For example, if the button has the id "btnSubmit", you can use the following code:
Button btnSubmit = findViewById(R.id.btnSubmit);
Step 3: Set the background color of the button using the setBackgroundColor() method. For example, to set the button color to red, you can use the following code:
btnSubmit.setBackgroundColor(Color.RED);
Step 4: Save the Java file and run your app to see the changes reflected in the button’s color.

Method 3: Via Styles and Themes
Using styles and themes is a powerful method to change the button color in Android Studio. It allows you to define a common style for multiple buttons and apply it across your app. By modifying the styles and themes, you can easily change the button color in one central place. Here are the steps to change the button color via styles and themes:
Step 1: Open the "styles.xml" file located in the "res/values" directory.
Step 2: Define a new style or modify an existing style for the button. For example, to create a style named "ButtonStyle.Red", you can add the following code:
Step 3: Modify the XML layout file to apply the style to the button. You can do this by adding the "style" attribute to the button element and setting its value to the newly created style. For example:
Step 4: Save the XML file and run your app to see the changes reflected in the button’s color.
Pros:
1. Provides a centralized approach to change the button color.
2. Allows for easy customization of multiple buttons with a single modification.
3. Supports inheritance and cascading styles for efficient styling management.
