Even thought you are in onClickListener anonymous class, you can
always get your context (instance of activity via
your_activity_class_name.this)
cb.setOnClickListener(new OnClickListener()
{
TableLayout tl;
@Override
public void onClick(View v)
{
if (((CheckBox) v).isChecked())
{
if (tl == null)
{
Context c = MyActivity.this;
