Answer 1

Button btn = findViewById(R.id.menu_btn);

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        if(!drawer.isDrawerOpen(Gravity.START)) drawer.openDrawer(Gravity.START);
        else drawer.closeDrawer(Gravity.END);
    }
});
