Wish: Ability to call SetContentDescription() on Android views

[Steve]

Greetings,

Most native Android widgets provide a method called SetContentDescription() which allows developers to provide info useful to blind/low vision users who rely on Android screen readers like Talkback, Spiel, and Mobile Accessibility. I specifically want to be able to set this field for views like the seekbar control so that blind users of an app I'm working on will be able to more easily determine what they are adjusting when they change the bar's position.

You can use the reflection library to do it:

Sub Activity_Create(FirstTime As Boolean)
   Dim b As Button
   b.Initialize("")
   SetContentDescription(b, "example")
End Sub

Sub SetContentDescription(v As View, Text As String)
   Dim r As Reflector
   r.Target = v
   r.RunMethod2("setContentDescription", Text, "java.lang.CharSequence")
End Sub

Ahah, very cool, and props as always to you for the quick response and Andrew for the reflection lib. The latter especially opens up a lot of possibilities for those of us who are bless/cursed to know Java.

I will add TalkBack to the planned features list. I do not currently know whether it will work or not.
