Updating some rows dynamically in TableLayout

Question

I'm adding rows to my TableLayout dynamically and each row has more than one TextView.

I want to loop for each row in my TableLayout and I want to update some rows (not every row), for example the text of TextView in my rows. How can I manage this?

Answer 1

Loop through the children of the TableLayout, they should be TableRows (or another layout) - skip the ones you don't want to update. Loop through or findViewById the children of the TableRow (or whatever) which will be your TextViews

When you add the TextView / CheckBox to the TableRow, you can set the View's id with setId(R.id.id_of_the_view) (which you might want to add to the res/values/ids.xml file).

Then loop through like so:

TableLayout tableLayout = null;
for(int n = 0, s = tableLayout.getChildCount(); n < s; ++n) {
    TableRow row = (TableRow)tableLayout.getChildAt(n);
    TextView name = (TextView)row.findViewById(R.id.tv_name);
}

since you're using row.findViewById, you're looking for a specific id inside a specific row.
