How to Change the Background Color of Button in Android using ColorStateList?
ColorStateList is an object which can define in an XML file that can be used to apply different colors on widgets (such as Buttons, etc) depending on the state of Widgets to which it is being applied. For Example, There are many states of Buttons like (pressed, focussed, or none of them ) and other widgets states like enable, checkable, checked, etc, Using Color State List is a nice way to change the color of the button without using shape drawables or custom images. One should remember the color state list can be used anywhere, where color is used. The color state list is defined in XML and saved under the res/color folder. The root element of the color state list is a selector and the item element is defined for each state that you want to define the color by using color and alpha attributes. The default color should be the last element which is used when color for a specific state is not defined. A sample GIF is given below to get an idea about what we are going to do in this article.
