如何使复选框仅在选中第一个复选框后可见

Question

我仍然是 android 的学习者，请尝试在 android 中执行以下操作。我希望我的复选框仅在单击第一个复选框后才显示其他复选框，但如果未选中第一个复选框，则其余复选框应该不可见。例如Class 1: checkbox, should only show Class 2:checkbox only when Class 1: checked has been selected 其余checkbox依此类推。请在下面找到我的代码。一旦有效，我愿意立即接受答案

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

    switch (buttonView.getId()) {
        case R.id.chk_clas1:
            //do stuff
            if (chk_clas1.isChecked()) {
                if(c1.equals("0")){adddate(txt_clas1);}
                clas="1";
                fdate=txt_clas1.getText().toString();



            } else {
                txt_clas1.setText("");


            }
            break;
        case R.id.chk_clas2:
            //do stuff

            if (chk_clas2.isChecked()) {
                if(c2.equals("0")) {adddate(txt_clas2);}
                clas="2";

这不是代码，只是一个想法.. 我脑子里有东西：

//Initially
chkBx2.setVisibility(View.INVISIBLE);

onCheckListener-> //just showing idea, not code

if(chkbx1.isChecked()){
     chkBx2.setVisibility(View.VISIBLE)
}
