It's actually quite crazy.
I had similar problems with scroll view.
But from what you are saying, you are interested in scrolling the text-view.
I would presume that the text-view has scroll-view bundled in it.
If things are not working out, then try this (at least this is what I did):
Screen-on can be done in two ways:
1. User pressing the power (or home button)
2. Through code: by using power manager - wake lock - with screen-on flag.
Either ways, I get a 'Intent.ACTION_SCREEN_ON' intent.
