Answer 1

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.

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)

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);

Answer 4

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);

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.
