Change the text format of the switch and get a list of all countries and put it in Android spinner

Question

Hi below is a screenshot containing a list of details to fill in by the user. Since you can see that the gender selection switches do not match the rest of the text in action. This is a bold text. I would like to make it look like the remaining text in action, how can I do this?

In addition, instead of the user entering the name of the state and country, I would like to provide a list of all countries in the spinner, and depending on the country selected by the state, the counter should be filled with the cities of the selected country. How can i do this?

Below is my xml code for the above activity
