addView to TableRow programatically in for loop

Question

I'am stuck for about 2 hour in order to try to create a TableRow who was multiples infalted layouts in it.My code looks like this:

LayoutInflater inflater = LayoutInflater.from(this);
TableLayout tblLayout = inflater.inflate(R.layout.tblL,parent,false);
TableRow tableRow = (TableRow) tblListItems.findViewById(R.id.tableRow );
View headerCell = inflater.inflate(R.layout.header_col,tblListItems,false);
TextView tvCellName = (TextView) headerCell.findViewById(R.id.tvCellName);

    for(String item: items) {

        tvCellName.setText(item);

        tableRow.addView(tvCellName);
    }

relativeLayout2.addView(tblLayout);

The error I get :

The specified child already has a parent. You must call removeView() on the child's parent first.

What I'am doing wrong and how should I do it right ?

A view can only have one parent. You're trying to add the same view over and over again.

for(String item: items) {

    tvCellName.setText(item);

    tableRow.addView(tvCellName); // this will add the same view.
}

If you want to add another view you need to create the view dynamically, inside the for, and not inflate it, like:

tvCellName = new TextView(this);//this creates a new view, that doesn't have a parent.

edit

Inflate your views inside the for:

 View headerCell;
 TextView tvCellName;
 for(String item: items) {
        headerCell = inflater.inflate(R.layout.header_col,tblListItems,false);
        tvCellName = (TextView) headerCell.findViewById(R.id.tvCellName);
        tvCellName.setText(item);
        tableRow.addView(tvCellName);
    }

The problem is that my TextView need to be from a layout that was inflated. TextView tvCellName = (TextView) headerCell.findViewById(R.id.tvCellName);

You need to create the view dynamically. Your problem is not that. Your problem is that a view CAN'T be added multiple times.

Sorry. The thing is that I don't need to add tvCellName to tableRow. I need to add headerCell which has a TextView in it on the table row.
