如何避免Android TalkBack读取SwitchCompat TextOn / TextOff

Question

I have a SwitchCompat with a text that I set via SwitchCompat.setText(). In my case this text is only "On" or "Off". The problem is Android TalkBack will then read for example "On ON, Switch, double tap to..." Also setShowText(false) doesn't help.

Answer 1

I think you should use .setContentDescription() instead.

This is the method primarily used for accessibility support. You can read its documentation here:

https://developer.android.com/reference/android/view/View.html#setContentDescription(java.lang.CharSequence)

Also, following accessibility guidelines, you shouldn't get rid of the actionable text provided ie "ON double tap to.."

Hope this helps!

Answer 2

The solution is to use:

mToggle.setTextOff("");
mToggle.setTextOn("");

Then only the text you set via setText() is being read. Don't know if this strange behavior is a bug or works as designed, it doesn't seem right to me though.
