Why won't my ClickListener work?

Button[][] arr = {
            {b1,b2,b3,b4,b5},
            {b6,b7,b8,b9,b10},
            {b11,b12,b13,b14,b15},
            {b16,b17,b18,b19,b20},
            {b21,b22,b23,b24,b25},
            {b26,b27,b28,b29,b30},
            {b31,b32,b33,b34,b35},
            {b36,b37,b38,b39,b40}
};
View.OnClickListener btap = new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                view.setBackgroundColor(Color.RED);
            }
};

Can you try adding Log.i(...) inside onClick() to see if this method gets called?

Early on in the file there is this bit of code: setContentView(R.layout.file1);

But all 40 b's are in file2, so I tried this:

final View.OnClickListener listener2 = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            setContentView(R.layout.file2);
            final View.OnClickListener listener = new View.OnClickListener() {
                @Override
                public void onClick(View view){view.setBackgroundColor(Color.RED);}
            };
            for(int i=0;i<=5;i++){arr[0][i].setOnClickListener(listener)}
        }
 };
