如何让alertDialog框在点击按钮时消失？

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("提示");
builder.setMessage("确定要执行该操作吗？");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 执行相关操作
        dialog.dismiss(); // 关闭对话框
    }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.dismiss(); // 关闭对话框
    }
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
