Chrome自定义标签：图标状态并响应用户操作

[英]Chrome Custom Tabs: Icon state and responding to user actions

原文 2015-06-19 09:42:38 3 2 android/ google-chrome/ chrome-custom-tabs

It looks like the custom tab icon is static, so it couldn't respond to user changes or external changes? 看起来自定义选项卡图标是静态的，因此它无法响应用户更改或外部更改？

To take the Pinterest example, if Pinterest has a custom tab icon like "Pin It" and user clicks on it, can it be changed to "Pinned". 要获取Pinterest示例，如果Pinterest有一个自定义选项卡图标，如“Pin It”并且用户点击它，可以将其更改为“Pinned”。 If not, how should the app/tab provide user feedback after such an action? 如果没有，应用程序/选项卡应该如何在此类操作后提供用户反馈？

2 个解决方案

Icon can not be changed at the moment. 目前无法更改图标。 Not sure how to handle that though. 不知道如何处理。

This feature is now [implemented in Chrome 46] ( https://codereview.chromium.org/1291083004/ ) together with the next version of android support library that will be released soon. 此功能现在[在Chrome 46中实现]（ https://codereview.chromium.org/1291083004/ ）以及即将发布的下一版Android支持库。

There are two ways to update the icon of action button: 有两种方法可以更新操作按钮的图标：

Using support library, you could call CustomTabSession#setActionButton(), once you have got an CustomTabSession object after creating a custom tab. 使用支持库，在创建自定义选项卡后获得CustomTabSession对象后，可以调用CustomTabSession＃setActionButton（）。
If you prefer not to use the easy and beautiful support library, you could also achieve the same goal by binding to the CustomTabsService , call updateVisuals() and pass the IBinder object you got previously when binding. 如果您不想使用简单而美观的支持库，您也可以通过绑定到CustomTabsService来实现相同的目标，调用updateVisuals（）并传递绑定时先前获得的IBinder对象。
