在android中弹出菜单没有关闭？

// 在Activity或Fragment中
Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        PopupMenu popupMenu = new PopupMenu(MainActivity.this, v);
        MenuInflater inflater = popupMenu.getMenuInflater();
        inflater.inflate(R.menu.popup_menu, popupMenu.getMenu());
        
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.action_item1:
                        // 处理第一个菜单项点击事件
                        return true;
                    case R.id.action_item2:
                        // 处理第二个菜单项点击事件
                        return true;
                    default:
                        return false;
                }
            }
        });
        
        popupMenu.show();
    }
});
