If you are giving a try to an alternate solution by doing it in java file you can try the code below in onCreate method ,this will create a button on top of google map

Button button = new Button(this);
button.setText("Click me");
addContentView(button, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent i=new Intent(this,SecondActivity.class);
                    startActivity(i);

                }
            });
