Question

I have a dialog box that contains a Scrollview, which contains a layout with two TimePickers.

The timepickers are the newer style ones, what\'s in ICS.

Because the link from Klemens Zleptnig is broken, here is a complete example. This fix helps with the scroll of a TabLayout too btw. I excluded the area around the big numbers in the top of the TimePicker because they don't need the scroll event anyway.

xml:

<com.name.app.MyTimePicker
                android:id="@+id/timePicker"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
.../>

java:

public class MyTimePicker extends TimePicker {
    public MyTimePicker(Context context) {
        super(context);
    }

    //This is the important constructor
    public MyTimePicker(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev)
    {
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
        //Excluding the top of the view
            if(ev.getY() < getHeight()/3.3F)
                return false;

            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }

        return false;
    }
}

I had the same problem when using the Holo theme, and here is where I found the solution: https://groups.google.com/forum/?fromgroups#!topic/android-developers/FkSfJI6dH8w

You must implement your custom DatePicker or TimePicker and override the following method:

@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
    if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
    {
        ViewParent p = getParent();
        if (p != null)
            p.requestDisallowInterceptTouchEvent(true);
    }

    return false;
}
