Answer 1

Here you go:

View v = (View)findViewById(R.id.content);
    v.setOnLongClickListener(new OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
        Intent i = new Intent(context, NewActivity.class);
        startActivity(i);
        return true;
        }
    });

(Obviosly replace variable names with your own)
