Using android studio.

Create an Android Application that displays in a column: a text, a square, and a button - text on top, a square in the middle, and the button underneath it. Initially the text is displayed in black and the square has a white background and the border in black. The button has an image as its background.

If the user clicks on the button, then the text color becomes red and the square's background green. On the next click the colors are switched: the text is now in green and the square is in red. The next click on the button, the text goes back to red and the square in green. This circular operation of changing colors keeps going on every time the user clicks on the button.
