Android change layout depending on if statement

Im trying to inflate a view depending on screen size so I can use different layouts I have tried the following

double screen_size = 8

 if screen_size >= 10 {
        layoutInflator =(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View row = layoutInflator.inflate(R.layout.mylist, parent, false);
             } 

if screen_size >= 5 && screen_size  <=9){
        layoutInflator =(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View row = layoutInflator.inflate(R.layout.mylist2, parent, false);
             } 

TextView textview1 = (TextView) row.findViewById(R.id.textView1);

I get an error on the Textview saying "row" cannot be resolved even tho the if statement is being run

If I change to

double screen_size = 8

if screen_size >= 10 {
        layoutInflator =(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View row = layoutInflator.inflate(R.layout.mylist2, parent, false);
             } 

if screen_size >= 5 && screen_size  <=9){
        layoutInflator =(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View row = layoutInflator.inflate(R.layout.mylist2, parent, false);
             } 
 View row = layoutInflator.inflate(R.layout.mylist, parent, false);

TextView textview1 = (TextView) row.findViewById(R.id.textView1);

it runs fine but always runs layout mylist instead of mylist2

Any ideas where im going wrong

Any help appreciated
