问新手求教 如何把if丢进去方法里面调用？

        public void duoxuan() {
        Intent intent=new Intent(MainActivity.this,SecanActivity.class);
        if(ck1.isChecked() && ck2.isChecked() && ck3.isChecked() && ck4.isChecked()) {
            intent.putExtra("Aihao","唱"+"跳"+"rap"+"篮球");
            startActivity(intent);
            finish();//关闭界面
        }
        else if(ck1.isChecked() && ck2.isChecked() && ck3.isChecked()) {
            intent.putExtra("Aihao","唱"+"跳"+"rap");
            startActivity(intent);
            finish();//关闭界面
        }
        else if(ck1.isChecked() && ck3.isChecked() && ck4.isChecked()) {
            intent.putExtra("Aihao","唱"+"rao"+"篮球");
            startActivity(intent);
            finish();//关闭界面
        }
