A question about setting TextView ID's in Android

Posted on 2011-03-18
Last Modified: 2012-05-11

       I made a dynamic table that expands/contracts according to the data received, and it has two TextViews in each row.

What I'm trying to do is, when a person clicks a row or textview, it would send the ID of the value clicked, rather than the value itself, and the ID is a value from the database that cannot be displayed on the screen.

I have tried variations of the following method... assigning the value of the ID to another variable and us it as the id of the TextViews, but none of the variations worked... and the program just crashed, or it just didn't respond.

Can anyone help me out?

Thanks in advance!

I reckon what you have is some soft of list (1st xml) with customised row (2nd xml).

Android gives you the position in the list for each row, but the IDs in the individual row are the same for all rows.
So perhaps you should send row position rather than textview ID.

Some code would be helpful to answer this question better.

TableLayout tl = (TableLayout)findViewById(;
        /* Create a new row to be added. */
        TableRow tr = new TableRow(this);
        tr.setLayoutParams(new LayoutParams(
             /* Create a Button to be the row-content. */
             final TextView tv = new TextView(this);
             final TextView tv1 = new TextView(this);
             for(int i = 0; i < pickup_dates.size(); i++){
            	 tv.setLayoutParams(new LayoutParams(
               	 tv.setPadding(0, 10, 10, 10);
               	 tv.setOnClickListener(new OnClickListener(){
					public void onClick(View v) {
Intent selectedIntent = new Intent(getParent(), OrderDetail.class);
					     b.putString("bookingId", booking_ids.get(tv.getId()));
TabGroupActivity parentActivity = (Tabs)getParent();
					     parentActivity.startChildActivity(newActivity, selectedIntent);
            	 tv1.setLayoutParams(new LayoutParams(
            	 tv1.setPadding(0, 10, 10, 10);
            	 tv1.setOnClickListener(new OnClickListener(){
 					public void onClick(View v) {
 						 Intent selectedIntent = new Intent(getParent(), OrderDetail.class);
b.putString("Id", booking_ids.get(tv1.getId()));
 TabGroupActivity parentActivity = (Tabs)getParent();
 					     parentActivity.startChildActivity(newActivity, selectedIntent);

   /* Add row to TableLayout. */
   tl.addView(tr,new TableLayout.LayoutParams(

Open in new window

This is the basic version of what I have, I need to get associate the ID of what I've selected with its ID in the database.

I know how to get the ID from the database... but i just don't know how to set it as an ID for the TextViews.

I'm gonna see if using a HashMap makes any difference.
