One of the most often used User Interface elements is TextView. The user experience is improved, and the application looks better, due to the clear and organized text.

There are two methods of changing the color of a TextView and the code for that has been given in both Java and Kotlin Programming Language for Android, so it can be done by directly adding a color attribute in the XML code or we can change it through the MainActivity File. By default, the color of the text will be black until it is changed.
