b1.setOnCheckedChangeListener(new?CompoundButton.OnCheckedChangeListener()?{
????@Override

????????Log.i("msg0",?b+"?");
????????if(b)?{
????????????String?text?=?b1.getText().toString();
????????????Log.i("msg",?text);

????}
});b1.setOnCheckedChangeListener(new?CompoundButton.OnCheckedChangeListener()?{
????@Override
????public?void?onCheckedChanged(CompoundButton?compoundButton,?boolean?b)?{
????????Log.i("msg0",?b);
????????if(b)?{
????????????String?text?=?b1.getText().toString();
????????????Log.i("msg",?text);
????????}
????}
