SearchManager.on遣散listener从未被调用

Question

我的目标是复制"播放音乐"应用程序的搜索功能。从我收集到的信息来看，当我按下搜索按钮时，将创建一个新活动，并自动展开搜索视图。当按下箭头或后退按钮(用于关闭搜索小部件)时，活动将关闭。一切正常，除了on解散方法没有被调用。非常感谢任何帮助。谢谢!

搜索活动是通过一个意图，当搜索图标被按下。下面是在搜索活动中创建搜索小部件的代码，它模仿了上面描述的播放音乐。

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu items for use in the action bar
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu_option, menu);
        // Associate searchable configuration with the SearchView
        SearchManager searchManager =
                (SearchManager) this.getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView =
                (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(
                searchManager.getSearchableInfo(getComponentName()));
        MenuItem searchMenuItem = menu.findItem(R.id.action_search);
        searchMenuItem.expandActionView();
        searchManager.setOnDismissListener(new SearchManager.OnDismissListener() {
            @Override
            public void onDismiss() {
                //Method never called. Logs don't show up/
                Log.i("1234Dismiss", "onDismiss called");
                finish();
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

请用这个代替。它在我所有的应用程序中都非常适合我。

MenuItemCompat.setOnActionExpandListener(searchMenuItem,
                new MenuItemCompat.OnActionExpandListener() {
                    @Override
                    public boolean onMenuItemActionCollapse(MenuItem item) {
                        // Do what you want to do when the search is collapsed
                        return true; // Return true to collapse action view
                    }
                    @Override
                    public boolean onMenuItemActionExpand(MenuItem item) {
                        // Do what you want to do when the search is expanded
                        return true; // Return true to expand action view
                    }
                });
