The appearance of applications along with their correct and better performance is very important and care must be taken in designing a user-friendly interface and attractive graphical interface.

What is a theme?

The theme is actually the style that is considered and applied to the whole application. For example, when we want to define what color is the application menu, we can give it a theme and by defining the theme, apply the desired color to the application menu. Of course, it should be noted that we apply the desired feature and value that is the desired color in the theme for the application menu, in this case, it is no longer necessary to specify the attribute and value for each activity separately.

What is style?

A style is placed inside the XML file. The XML file that has the attributes and style values ​​is in the res / values ​​/ directory. It should be noted that this file will have resources tags and will also have features and values ​​for styling.You should note that the name of this file can be selected as you wish and you can choose anything as the name of this file, but the important point here is that it must be an XML file extension.

Styling and styling in Android

Android system allows programmers to change the appearance of the application by applying and assigning some features to the XML file and produce an attractive graphical user interface. In this case, programmers can make all the appearance changes they want inside the XML file and then see the result in its appearance. Appearance changes that programmers can apply include changing the background color, creating some attractive images and boxes, using attractive fonts and animations, and more.Note that if an entry inside the source file is used to style and style the view, it is called a style. But if the same entry is used to style and style the activity, it is known as a theme.Just create an XML file inside the / res / values folder to change the style or theme. Note that the root node of the XML file must be resources. This file must use style tags that have names.The code below shows an example of creating and assigning style.
