Additionally, you can feel free to use the Search bar selection mechanism as a replacement for tabs since it’s really just a fast pivot on a data set. If you have more than 3 data sets, tabs become problematic since no more than 3 can be onscreen at once. For example, look at how we implemented the Profile switching mechanism below:

The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app

The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app. QuickContact for Android provides instant access to a contact's information and communication modes.

<!-- Variation on the Light theme that turns off the title --><style name="Theme.IOSched" parent="android:style/Theme.Light">    <item name="android:windowNoTitle">true</item>    <item name="android:windowContentOverlay">@null</item></style>

The android:windowContentOverlay is your shadow, and setting it to @null in your theme will eliminate it. You can see this in action in the Google I|O 2010 conference app, which uses many of the same UI conventions as does the new Twitter app. However, right now, the Twitter app has not yet been open-sourced, which is why I point you to the I|O app. The code fragment above is from that app's styles.xml resource.

This is a demo Android project showing how it's possible to have QuickActions and Popdown menu interface actions like those in the Twitter App.

思路转换的失败

针对的用户群体动辄就是全球目标用户，在商业判断和分析上，最基础的一个考量就是用户群体和业务模式的总量的收益是否足够大，对用户群体的研究和商业判断分析完全根据市场分析报告和数据来做判断。因此，不可避免地在程序创意思路上会沿用以前的工作思路和分析方法。 在考虑Android上的创意的同时，不自觉地就考虑和分析了如下几个方面的问题： 1. 是否为用户所必需？ 2. 技术上是否领先？ 3. 程序的粘性是否足够？ 4. 用户群体是否足够大？ 因此，沿用这个思路，不可避免地就会往大的应用和大的服务上去思考和做出判断。

经过反复地反省和对比，初步得出了这样的失败教训： 1. 对于个人开发者和小型团队来说，不适合做过于基础的程序。操作的模式和理念上的创新与用户的接受度有相当的距离。这样的事情只有大公司才有财力和可能进行推广。比如说手机生产商，他们可以通过预置的方式进行推广。而对个人开发者来说，得先证明你的想法是成功的，不能假设一个会成功的需求和应用，然后卖给设备厂商。 2. 个人开发者和小型团队不适合做大的程序，尤其是开发时间不要超过2个月。4个人，3个月的时间，对于一个小团队来说 ，是相当宝贵的。这不仅仅是时间和金钱的问题，更多的是信心问题。 3. 用户能否真正接受你的想法，是一个关键性的问题。设想和推导都很完美，唯独缺了用户是否真正喜欢和接受这一条，又没有方法进行快速地验证和试错，基本上不能成功。

The concept of ActionBar has been introduced with the Twitter application for Android. More recently, we have seen this widget in the Google I/O 2010 schedule application. To sum up, an ActionBar can be considered as an advanced title bar that is capable of: containing several ActionBaritems (similar to buttons) being styled so that the general look’n'feel of the application is in accordance with the underlying brand/visual identity containing a title to show the user a summary of the screen content featuring several user interaction pattern.
