问题描述
我已经开发了一个应用程序为视障人士。我创建了简单的手势触摸一样，双水龙头我的应用程序和使用的读数文本TTS。我有一个奇怪的问题：
I have developed an app for visually impaired. I created easy gestures like touch, double taps for my app and using tts for readings texts. I have a strange problem:
当我喜欢启用对讲功能辅助。我的应用程序的手势被停用，我不能用我的任何应用程序内的手势。
When I enable accessibility function like talkback. My apps gesture get disabled, I can't use any of my in-app gestures.

推荐答案
的Android版本，你定位？
Which version of Android are you targeting?
您可能想看看的http：// support.google.com/nexus/bin/answer.py?hl=en&answer=2692469 为Android 4.1 +
You may want to look at http://support.google.com/nexus/bin/answer.py?hl=en&answer=2692469 for the Android 4.1+.
基本上，对讲将取代许多手势，但在Android的某些版本中，你可以通过访问
Basically, Talkback will replace many of the gestures, but on some versions of Android you can adjust these by going to
Settings > Accessibility > TalkBack > Settings > Manage shortcut gestures.
因此，这将是有意义的只接受已经被支持的价值观，而不是试图绕过它。
So it would make sense to just accept the values that are already supported, and not try to get around it.
此外，如果用户使用浏览触摸你没有提到（的 http://support.google.com/nexus/bin/answer.py?hl=en&answer=2692788 ）
Also, you didn't mention if the users are using Explore Touch (http://support.google.com/nexus/bin/answer.py?hl=en&answer=2692788)
如果你想捕捉这些，看来您可以使用 onHoverEvent 根据这样的问题：
If you want to catch these, it appears that you can use onHoverEvent according to this question:

更新：
您可以看看关于如何判断对讲激活了这个问题：
You can look at this question on how to tell if Talkback is active:
<一个href=\"http://stackoverflow.com/questions/11831666/how-to-check-if-talkback-is-active-in-jellybean\">How检查对讲活跃在软糖
如果是，告诉他们需要把它关掉你的程序工作，也许是用户。
If it is on, tell the user they need to turn it off for your program to work, perhaps.
