setListener();
}
private void setListener() {
// TODO Auto-generated method stub
cbMale.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View view) {
// TODO Auto-generated method stub

}
});
cbfaMale.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View view) {
rbMale.setChecked(!((CheckBox)view).isChecked());

}

});
tv.setOnClickListener(new OnClickListener(){


@Override
