Dynamic TableLayout in Android

As my previous post for dynamic ListView is quite helpful for few readers, here I am with a similar post. Here I am creating dynamic table. The concept looks similar but the method of creation will differ. While creating a table, we will need to create the TableLayout and from the code we will be adding rows and columns. As the table rows are more, we have to put the table into a ScrollView.

Here is same example given for ListView but will provide the country and its abbreviation in a table.

//CountriesList.java

package com.dynalist;

public class CountriesList {
	public static String[] countries = { "Afghanistan", "Albania", "Algeria",
			"American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica",
			"Antigua and Barbuda", "Argentina", "Armenia", "Aruba",
