为什么没有在Android的进度对话框取消按钮？ [英] Why is there no cancel button in Android's progress dialogs?

问题描述

我现在面临一个头刮时刻类似于<一href="http://groups.google.com/group/android-developers/browse_thread/thread/cdae98b7832b4754/567ffa7107a73f70"相对=nofollow>这个人（从2008年1月）出现时，我意识到，没有在Android的进度对话框或微调取消按钮。现在是2009年7月，我刚刚安装的Andr​​oid的蛋糕版本。有这个事情改变了吗？如果没有，你添加一个取消按钮进入对话框和你怎么办呢？

I'm facing a head-scratching moment similar to what this person (from Jan 2008) experienced when I realized that there is no cancel button in Android's progress dialog or spinners. It is now July 2009 and I've just installed the cupcake version of Android. Has this thing changed? If not, are you adding a cancel button into the dialogs and how do you do it?

推荐答案

我不是Android的用户还是开发者，但我觉得在链接到的线程是pretty的体面给出了答案：有一个的硬件的背在所有Android设备的关键。用户应该知道，以preSS背靠背出什么活动，他们目前正在研究。

I'm no Android user or developer, but I think the answer given in the linked-to thread is pretty decent: there's a hardware "back" key on all Android devices. Users are supposed to know to press Back to back out of whatever activity they're currently in.

因此​​，UI设计师觉得这是不必要的，包括一个图形用户界面回/取消键。这可以被视为干原则的用户界面应用程序;如果有已经在做事情的一种方式，这就足够了。

Thus, the UI designers feel it's unnecessary to include a GUI back/cancel button. This could be viewed as the UI application of the DRY principle; if there's already one way of doing something, that's enough.
