Android - Button not clickable when button text set to all uppercase -

-

i developing android application in text of button set dynamically (e.g. "follow" or "following") through button.settext("text") method. functionality works when button text lowercase, when text set "follow" or "following" button become unclickable. onclick method never activated.

however, logcat displays:

07-21 16:18:17.228  31640-31640/co.example.example d/viewrootimpl﹕ viewpostimeinputstage action_down

so somehow click being registered action_down touchevent when user taps button. suggestions?

thanks.
