Android 2.3.3姜饼中的选项是什么?就像Android 4.0.4中的辅助功能选项("Explore by touch") ICECREAMSANDWICH一样

Question

我想使用谷歌的无障碍对讲机应用程序，以便盲人可以访问它。我试着在我的安卓系统4.0.4 IcecreamSandwich和2.3.3姜饼上使用它。

   Settings for 4.0 Icecreamsandwich are as follow:
         settings --> accessibility --> talkback - ON --> back --> Explore by touch - ON

   And Settings for 2.3.3 Gingerbread are as follow:
         settings --> accessibility - check --> talkback - check

  There is no option for "Explore by touch" in android 2.3.3 gingerbread.
   What is the alternative for "explore by touch" option in Android 2.3.3 Gingerbread ?

我在谷歌群https://groups.google.com/forum/?fromgroups=#!topic/android-developers/bqsP6Hbs5kE上也问过同样的问题

Answer 1

在姜饼中没有与触摸探索相同的功能。它是和冰激凌三明治一起推出的。

在ICS之前，Talkback只能说出可聚焦的视图。

对Android 2.3.3 touch by explore的回答表明，来自Eyes-Free Project的AccessibilityShim库可以用来在你的应用程序中实现触摸浏览功能。
