Main = (LinearLayout) findViewById(R.id.main);

    Main_1 = new LinearLayout(this);
    LinearLayout.LayoutParams sudoku_1_lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);
    Main_1.setLayoutParams(sudoku_1_lp);
    Main_1.setWeightSum(100);
    Main_1.setOrientation(LinearLayout.VERTICAL);
    Main_1.setId(100);

    //Layout for sudoku_board 
    sudokuboard = new LinearLayout(this);
    LinearLayout.LayoutParams sudokuboard_lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,0,80.0f);
    sudokuboard_lp.setMargins(1, 1, 1, 1);
    sudokuboard.setLayoutParams(sudokuboard_lp);
