Как сделать несколько Expandable Layout в одном Activity

у меня есть Activity в котором есть ExpandableLayout и при добавлении его он не работает. То есть я нажимаю на 1 и он раскрывается и закрывается как и надо а при нажатии на второй ничего не происходит.

Java

import com.example.admin1.bottomtabexample.R;

public class Customs extends BaseCollapseActivity {

    @Override
    protected int getLayoutResourceId()
    {
        return R.layout.activity_customs;
    }

    @Override
    protected int getExpandableLayoutId() {
        return R.id.layout_expandable;
    }

    @Override
    protected int getButtonId() {
        return R.id.button;
    }
}
