need help with this android stuido mobile app question:

For this first part, you will create a single UI screen having one text field, centered at the top of the screen, and one bu#on. The text field will ini!ally display the text "Tap to Change Color". A user should be able to click into the text field and then type whatever he or she wants through the devices so$ware keyboard. Every !me the user taps the change color bu#on, the app will generate a random color using RGB values and then change the text in the text field to that color. The app will further display the RGB values of the color chosen in the format COLOR: xr, xg, xb where x is the value of the color on the red, green and blue channel respec!vely. The app must also display the HTML color code of the color generated. For example: COLOR: 255r, 0g, 0b, #FF0000 would be displayed if the random color picker chooses pure Red.
