Question

我的目标是复制“播放音乐”应用搜索功能。从我可以收集的信息中，当我按下搜索按钮时，会创建一个新活动，并自动展开搜索视图。当按下箭头或后退按钮以关闭搜索小部件时，活动将关闭。一切都有效，除了没有被调用的onDismiss方法。任何帮助深表感谢。谢谢！

当按下搜索图标时，搜索活动通过意图启动。您可以在下面看到在搜索活动中创建搜索小部件的代码，该代码模仿播放音乐，如上所述。

@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);
    }

请改用它。它在我的所有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
                    }
                });

从未调用过SearchManager.OnDismissListener
