Android: Creating TableRow rows inside a TableLayout programatically

Posted July 1st @ 10:07 pm by Boyan Tsolov

In my quest to create a “Taxman” Android application I ran into the following problem:

I want to ask the user to enter their yearly income, after which the screen will flip and their after-tax income will be displayed in a table format for all Canadian provinces. (And for the future: all US states). The problem I ran into is creating a TableRow for each Canadian province in my main.xml. There are 13 provinces and territories, so 13 is not that bad to copy & paste in the main.xml; however, as soon as I have to copy & paste more than 2 times I start cringing and nausea kicks in. Personally I think “copy & paste” should not be in the programming vocabulary. Not only that, but I have 13 provinces now, what about when I have to enter 50 states! So, I had to find a way to create these new TableRow rows programmatically inside my TableLayout layout.

A great source for code snippets and answers to Android questions is http://www.anddev.org. I’m sure if you’re dabbling with Android then you’ve already come across this site. The particular post I read to do this is this one: Dynamically add rows to TableLayout. Commenters on that post were having problems getting this to work, but after I imported all the correct classes (android.widget.TableRow.LayoutParams is an important one to use) everything worked from the first time. I forced Eclipse to find most of the classes for me.

Below is the code from anddev.org, with my changes for my Taxman Android app. I’m too lazy to do a full-out beginning-to-end tutorial for this code snippet.

First I set my constants at the top of the Activity class:

public class Activity1 extends Activity implements OnTouchListener{

    int PROVINCE_Alberta = 0;
    int PROVINCE_BC = 1;
    int PROVINCE_Manitoba = 2;
    int PROVINCE_NewBrunswick = 3;
    int PROVINCE_Newfoundland = 4;
    int PROVINCE_Northwest = 5;
    int PROVINCE_NovaScotia = 6;
    int PROVINCE_Nunavut = 7;
    int PROVINCE_Ontario = 8;
    int PROVINCE_PEI = 9;
    int PROVINCE_Quebec = 10;
    int PROVINCE_Saskatchewan = 11;
    int PROVINCE_Yukon = 12;

    int numProvinces = 13;

There are 13 of them this time, there will be 50 of them for the States… technically this could be made into something much more malleable like an external config-type XML file.

Then in the onCreate method I created an array of String objects that will house all these provinces:

        String[] provinces = new String[numProvinces];
        provinces[PROVINCE_Alberta] = "Alberta";
        provinces[PROVINCE_BC] = "British Columbia";
        provinces[PROVINCE_Manitoba] = "Manitoba";
        provinces[PROVINCE_NewBrunswick] = "New Brunswick";
        provinces[PROVINCE_Newfoundland] = "Newfoundland and Labrador";
        provinces[PROVINCE_Northwest] = "Northwest Territories";
        provinces[PROVINCE_NovaScotia] = "Nova Scotia";
        provinces[PROVINCE_Nunavut] = "Nunavut";
        provinces[PROVINCE_Ontario] = "Ontario";
        provinces[PROVINCE_PEI] = "Prince Edward Island";
        provinces[PROVINCE_Quebec] = "Quebec";
        provinces[PROVINCE_Saskatchewan] = "Saskatchewan";
        provinces[PROVINCE_Yukon] =  "Yukon";

And right underneath that I create a TableRow for each item in the array provinces:

        // Get the TableLayout
        TableLayout tl = (TableLayout) findViewById(R.id.maintable);

        // Go through each item in the array
        for (int current = 0; current < numProvinces; current++)
        {
            // Create a TableRow and give it an ID
            TableRow tr = new TableRow(this);
            tr.setId(100+current);
            tr.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));   

            // Create a TextView to house the name of the province
            TextView labelTV = new TextView(this);
            labelTV.setId(200+current);
            labelTV.setText(provinces[current]);
            labelTV.setTextColor(Color.BLACK);
            labelTV.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            tr.addView(labelTV);

            // Create a TextView to house the value of the after-tax income
            TextView valueTV = new TextView(this);
            valueTV.setId(current);
            valueTV.setText("$0");
            valueTV.setTextColor(Color.BLACK);
            valueTV.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            tr.addView(valueTV);

            // Add the TableRow to the TableLayout
            tl.addView(tr, new TableLayout.LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
        }

The main.xml contains the following for the TableLayout:

        <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:stretchColumns="0,1"
                android:id="@+id/maintable" >
        </TableLayout>

And here is the final result:

So far I have the Ontario taxes working :). If you make $50,000 in Ontario, you’d be taking home $38,285.53.

    This is close to what I am looking for!

    I have the table building dynamically, called from onCreate() … my problem is that the table shows MONTH based figures with a Spinner above it. You can choose a new month from the Spinner and the table ‘is supposed to’ update the the selected month’s data.

    If you know… could you point me in the direction to be able to do this? I don’t under stand how to clear the table and draw a new one programatically in it’s place each time the month is changed…

    Obviously, I’m a little new to Android. I’m a little disappointed at how difficult tables have been so far. I eventually want to populate the table from a sql query result set, but I’ll get to that later once the testing works!

    Thanks!

    Paresh Mayani,
    I have the same problem, and then I remove “valueTV.setLayoutParams(new LayoutParams(
    LayoutParams.FILL_PARENT,
    LayoutParams.WRAP_CONTENT));
    ” from each textview, something is displayed.

    Try it!

    Good Tutorial !

    Initially I got plain black screen ie., nothing.

    Found out at last. Text color has been set to black and background colour hasnt been set.

    labelTV.setTextColor(Color.WHITE);

    I think you can see it now : )

    This is a great post. However, is it not possible to just create a table_row.xml that defines a single TableRow, and then inflate that and just populate it, as opposed to having to write out all the attributes in Java?

    In regards to the solution provided for the table row to show up (i.e. by removing the setLayoutParams for the TextView), how would i do it, if i have a long line of text.
    I tried removing the text wrapping, but then i lose part of my text too. Can anyone help me with this?
    For my entire text to show up, i wud need layoutparams to be wrap_content for my TextView

    and

    Dhara! I was having same problem, too. Do not forget to initialize tablelayout by tl = (TableLayout) findviewbyid(r.id.blabla)…

    Rip DVD Movies to iTunes iPhone, iPad, iPod all deliver the same message and it is to stay connected to music and videos nonstop all the days of their life as long as the battery is in the device. It is also a very remarkable statistic that most youngsters of today are the people who are so glued into the trend of plugging something into their ears and hearing it all the time. What one must realize is that these are not the only devices that are in the portable entertainment market today, but there are a host of other accompanied which have glutted this industry with so many models leaving a very confused consumer unless he has done his homework and is quite certain about this requirements and tastes. Most often it is not taste that hinders but the warmth of one’s pocket that matters more. The advent of iTunes mp4 This is one of the most versatile container formats of this century and it owes its popularity to the fact that almost all devices, is they phones or other portable entertainment devices, is all compatible with this format. This mp4 is able to contain a wide variety of files and it is this fact that makes it such a adaptable and user friendly format with people. For example, one may download a movie in the mp4 format and then play a wide variety of subtitles in various languages all in addition to this and have a picture of the DVD cover on it as well. All these can be succinctly contained within a single file and this is the true genius of the mp4 format. All these require that any DVD which has been released be converted to an mp4 format so that it can be watched on the go anywhere and at any time with the ease of lounging from a bus chair or plopped up with pillows on a train. Conversion of files In order for a person to view these on portable devices, one has to ensure that his DVD is converted into the mp4 format as well and this is where Aimersoft’s software products come of use. This product is great to rip DVD iTunes without any hassle, since it comes with an inbuilt tutorial on how to convert DVD to iTunes and all the required steps are enumerated very lucidly so that one can complete his task with minimum amount of fuss and flutter. There are many dvd ripper iTunes available to a person and therefore it is wise to read a few reviews before stepping off ripping DVD to iTunes. This is an important step, simply because many people have stored movies on their DVDs but would like them to be out in the open on their portable devices, so that they can watch the movie in their free time. This being the strongest reason possible, one must consider the usage of this software so that he can complete his conversion quickly and watch his movie on the move. copy DVD to iTunes rip DVD into iTunes
