Dynamic TableLayout in Android
April 1, 2011 6 Comments
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",
"Australia", "Austria", "Azerbaijan", "Bahamas", "Bahrain",

Output of the example looks like this:
How can we select a row from this and delete each selected row?Please help me……….
Thanks regards
use mapping method.. Map an ID array to the rows array. and one the click of the row you can get the row id(index) from which you can retrieve the mapped ID of the data.
Now as you got the ID, you can delete or update it.
Would it be more beneficial to create a structure containing different labels and the creating an array list of said structure? I am trying to use this in order to make a table that contains information about matches for a sporting event. So each column will have something like the team date venue. Do you think that would be better than having parallel arrays and would it work with the method of creating a dynamic table you have provided?
How to handle onClickListener in this case…I want to click on a TableRow and listener should be handled and value should be shown in form of Toast Message…How can I achieve this ??
Tried this but can’t see the list. The headers are created and visible, but the scrollable table below that is not… What am I doing wrong?
