Automatically scroll down an android layout after click event

Question

Is it possible to automatically scroll down the layout after a click event? I have this layout that displays a result when the user fills the data and clicks, but I’m afraid that on devices with smaller screen the result is hidden

I would like that if the person is on a device with a small screen and the bottom of the layout that displays the result is hidden, automatically after clicking is focused on the linear layout with the id "@+id/linearLayoutResulted" making the layout scroll down to be visible the result, this is possible?

Answer 1

Enter an id on ScrollView, and right after create an "event" post. When you do the action click on LinearLayout perform the event, as in the example below:

mScrollView.post(new Runnable() { 
        public void run() { 
             mScrollView.fullScroll(mScrollView.FOCUS_DOWN);
        } 
});

mScrollView is the id of Scrollview.
