Answer 1

the id is an intiger value not string: hope u ll get an idea from below code

 while (ctr<3)
{
   int layoutid;
    if(ctr==1)
    { layoutid = R.id.AbsoluteLayout1;}
    else{
     layoutid = R.id.AbsoluteLayout2;}
    mainlayout[ctr] = (AbsoluteLayout)findViewById(layoutid);
    ctr++;
}
---------------------------------------------

all these won post an error as they are handled as int itself manipulate as you want you cant use this as it is as

int[] ctra={R.id.xx,R.id.xxx};
  int i=0;
 while (ctr<3)
{
mainlayout[i]=(AbsoluteLayout)findViewById(ctra[i]);
i++;}
