Answer 1

Create a static object in order to listen to the button clicks.Based on this object handle events in all activities.

For example say Constants.class:

public class Constants {
    private static int buttonState1;
        public static int getButtonState(){
        return buttonState1;
    }
    public static int  setButtonState(int x){
        buttonState1=x;
    }


}

And in your activity:

Button bt1=(Button)  findViewById(R.id.bt1);

bt1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                                   Constants.setButtonState(1);
                         }
            });

And in other activities

if(Constants.getButtonState()==1)
                //do something
