How to set the starting position of a ScrollView?

The accepted answer is not working for me. There is no direct way to set the initial position of a scroll view.

However, you can set the initial position before drawing the scroll view, like this:

rootView.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
    @Override
    public boolean onPreDraw() {
        scrollView.getViewTreeObserver().removeOnPreDrawListener(this);
        scrollView.setScrollY(100);
        return false;
    }
});

You can also use scrollView.setScrollY(100) inside Handler, but that will be jerky while scrolling.

Yes, that is possible:

ScrollView.scrollTo(int x, int y);
ScrollView.smoothScrollTo(int x, int y);
ScrollView.smoothScrollBy(int x, int y);

can be used for that. The x and y parameters are the coordinates to scroll to on the horizontal and vertical axis.

Example in code:

    @Override   
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_layout);

        ScrollView sv = (ScrollView) findViewById(R.id.scrollView);
        sv.scrollTo(0, 100);
     }

In that example, once the Activity is started, your ScrollView will be scrolled down 100 pixels.

You can also try to delay the scrolling process:

final ScrollView sv = (ScrollView) findViewById(R.id.scrollView);

Handler h = new Handler();

h.postDelayed(new Runnable() {

    @Override
    public void run() {
        sv.scrollTo(0, 100);            
    }
}, 250); // 250 ms delay

Scrollview sw = (ScrollView) findViewById(R.id.scrollView);
sw.post(new Runnable() {
     public void run() {
           sw.smoothScrollTo(0, 5000);
     }
});
