Question

In arrayAdptor we use following code:

 final LayoutInflater inflater = activity.getLayoutInflater();
    row = (LinearLayoutCustom) inflater.inflate(R.layout.row, null);
    final TextView label = (TextView) row.findViewById(R.id.title);
    label.setText(position + "" + items[position]); 
    return row;

Now suppose some value are null (for example at position 2 , items[2] = null ) so i dont want to show it in row. i want to hide it. if i use

               row.setVisibility(View.GONE) 

it leaves a blank space at this row which i dont want. so what should i do?

Answer 1

You’ll need to have the adapter return the total number of non-null items with getCount and then keep a mapping of position to your internal data structure.

For example.
You have a list

1 - John
2 - null
3 - Bill
4 - Susan
5 - null

When getCount is called it returns 3.

Then when getView is called on position 1 you return the item at list[1].
getView on position 2 returns list[3] (as it’s the 2nd non-null),
and so forth.

This is the only way I’ve found to do this.
