Question

How should I implement a table of 15 by 15 cells if I plan to dynamically update the cells individually?

I began creating the table in my main.xml, but I don’t want to describe the table with 15 TableRow elements and 15 elements in each of those all in one body of code. I feel like even putting just the table itself in a separate file is too bulky. It is possible to create a file of a row and and a file of a table including the row 15 times and dynamically assign different IDs to each cell?

You could do comething like:

public void generateTable() {
    TableLayout tv = new TableLayout(context);

    for (int y = 0; y < 15; y++) {
        TableRow tr = new TableRow(context);
        for (int x = 0; x < 15; x++) {
            TextView tv = new TextView(context);
            tr.addView(tv);
            tv.setText("ID: " + (y*15 + x));
            tv.setId(y*15 + x);
            // And to allow for easy reading
            if (y*15+x % 2 == 0)
                tv.setBackgroundColor(0xffff0000);
            else
                tv.setBackgroundColor(0xff0000ff);
        }
    }
}
