While you create a table Row dynamically associate an Id with it and in onclick listener distinguish the row pressed with it's id

eg 
TableLayout tl=new TableLayout(context);
for(int i=0;i<20;i++){
TableRow tr = new TableRow(context);
tr.setId(i);
tr.setOnClickListener(this);
}

public void onClick(View view)
{

switch(view.getId())
{
case 1: 
doSomething();
break;
case 2: 
doSomething();
}

}

public void doSomething()
{

}


Similarly do it for a dialog
