you may create it as below:

ScrollView scroll = new ScrollView(context);
scroll.setBackgroundColor(android.R.color.transparent);
scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                                             LayoutParams.FILL_PARENT));
scroll.addView(yourTableView);

@JohnnyFive I guess ViewGroup should do fine here

if you have many elements first you need to wrap-up and add in the Scroll view; for example i need a many text view inside of scrollview, so you need to create ScrollView->LinearLayout->Many textview

                ScrollView scrollView = new ScrollView(context);
                scrollView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

                TextView textView = new TextView(context);
                textView.setText("my text");

                LinearLayout linearLayout = new LinearLayout(context);
                linearLayout.setOrientation(LinearLayout.VERTICAL);
                linearLayout.setGravity(Gravity.RIGHT);
                linearLayout.addView(textView);
                scrollView.addView(linearLayout);

this may help you.

    HorizontalScrollView hsrll = (HorizontalScrollView)findViewById(R.id.hrsll);

    b = new Button(this);

    for (int i = 0; i < 5; i++) {

        b.setWidth(LayoutParams.WRAP_CONTENT);
        b.setHeight(LayoutParams.WRAP_CONTENT);

        b.setText("b"+i);
        b.setId(100+i);

        hsrll.addView(b);
    }

instead of for loop just modify the code as your need(no of records in db). but this the code for creating buttons in dynamically.

ScrollViews can only have one child widget. If you want more children, wrap them in a container layout

yep,because of this you should create at least one Layout(exp:Linearlayout) in the ScrollView and then add Button(etc.) to the Layout.

I was doing it like this:

Create xml with LinearLayout inside the ScrollView
Create xml as item in ScrollView
In activity set main content as xml with ScrollView
Loop through all table elements with adding new View to LinearLayout form main view

For me works fine.

In Kotlin you can use the below code

    val scroll = ScrollView(context)
    scroll.setBackgroundColor(R.color.transparent)
    scroll.layoutParams = LayoutParams(
        LayoutParams.FILL_PARENT,
        LayoutParams.FILL_PARENT
    )
    scroll.addView(yourTableView)
