Android :: Scrolling EditText On ScrollView Programmatically

I am trying to make a non-editable EditText that is placed in a ScrollView and scrolling is controlled programmatically (when a left/right fling is detected).

Here's my simple layout:

CODE:..........

And here is my simple program:

CODE:.............

So, to explain it simply, I have two custom simplegesture classes that I attached to the EditText and the ScrollView. For the EditText, I'm trying to detect a left/right fling and when detected, I'm scrolling the it up 1 page up/down. The custom simplegesture attached to the ScrollView is to disable finger scrolling.

Here's a screen shot after a right fling was done: http://img830.imageshack.us/i/textcut.png/

I kinda works right now but I have two questions:

How do I control the scroll so that lines won't get "cut-off" (please refer to the picture above where the first line on the screen is a bit "cuf-off"). Why when I scroll the page up/down programmatically, the EditText is auto select-all (please refer to the picture above where the whole screen turns orange after scrolling)? Why when I changed MyGestureDetector to detect fling on the Y-axis (vertical fling) and programmatically scroll the EditText, it doesnt' work? It wouldn't work even if I made the change in ScrollGestureDetector too. Does it have something to do with the behaviour of the ScrollView?
