android - 搜索 View :Triggering onQueryTextChange on Collapsing of the searchView

Question

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            search(newText);

            return true;
        }
    });

我不想在 searchview 时执行 search(newText)折叠。

我试过了

if(searchView.isShown) search(newText);

和

if(!searchView.isIconified) search(newText);

但是当我关闭 searchview , searchView.isShown和 searchView.isIconified值将在触发后更新 onQueryTextChange .

我的 onCreateOptionMenu 代码:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_contacts, menu);

        addContactMenuItem = menu.findItem(R.id.action_add_contact);
        searchViewMenuItem = menu.findItem(R.id.action_search);
        searchView = (SearchView) MenuItemCompat.getActionView(searchViewMenuItem);
        MenuItemCompat.setOnActionExpandListener(searchViewMenuItem, new MenuItemCompat.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                addContactMenuItem.setVisible(false);
                if (contactListAdapter != null)
                    contactListAdapter.getFilter().filter(searchView.getQuery());
                return true;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                addContactMenuItem.setVisible(true);
                contactListAdapter.performGroupBasedFiltering(groupSpinner.getAdapter().getItemId(groupSpinner.getSelectedItemPosition()));
                return true;
            }
        });

        return true;
    }

请帮帮我!提前致谢。

试试这个用法 setOnActionExpandListener

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.search_menu, menu);

        MenuItem item = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
        searchView.setOnQueryTextListener(this);

               MenuItemCompat.setOnActionExpandListener(item,
            new MenuItemCompat.OnActionExpandListener() {
                @Override
                public boolean onMenuItemActionExpand(MenuItem menuItem) {
                    // perform your action here 
                    return true;
                }

                @Override
                public boolean onMenuItemActionCollapse(MenuItem menuItem) {
                    // perform your action here 
                    return true;
                }
            });




        return true;

    }

as per your comment

我需要 search(newText) 不在折叠时执行。

than set this searchView.setOnQueryTextListener(null); when you don't need
