Android : How use setID in android correctly?

I want to add layout with controls dynamically and in the future I want to save this data to DB.

public void onClickAdd(View view) {
        LayoutInflater ltInflater = getLayoutInflater();
        final LinearLayout subLayoutFields = (LinearLayout) findViewById(R.id.subLayoutFields);
        LinearLayout subLayoutFields1;
        final View view1 = ltInflater.inflate(R.layout.sub_fields, subLayoutFields, true);
        subLayoutFields.setId(countID);
countID++;
    }

And compiler did not finish successful.What's wrong with this?I get error on the

subLayoutFields.setId(countID);

Thank you...
