Question

How can i get one button to perform 2 operations.

Answer 1

something like this, set up a global variable i and set it to 0. then when you click the button the first time it will do the first code then set i to 1. the second time it will do the second code and set i back to 0, so you can loop through those 2 every other push of the button.

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.button1:
        if (i == 0) {
            //display 1 code
            i = 1;
        }
        if (i == 1) {
            // display 4 code
            i = 0;
        }

        break;
    }

}
