change the color of TextView when clicking on Button

Question

I have a text box with the title of a book There is a button next. How can I change the color in the textbox when the button is clicked?

Answer 1

In the onClick method of the button you are using you can something like this:

TextView title1 = findViewById(R.id.myTextView);
//Your "onclick" method
myButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        
        title1.setTextColor(Color.MyColor); //changing text color
    }
});

Here instead of myTextView, use your TextView id. Instead of MyColor choose your color, you either have to use the built in colors(i.e. WHITE, BLACK) or add a color of your own in values\colors.xml file with your desired name and use that here.
