android - 我可以在 android 的线性布局中声明这种类型的动态复选框吗？

Question

我想为 linearlayout 声明这种类型的复选框，并获取每个复选框 ID 以及选中和未选中的值
此类型的复选框值获取

for(l=0;l<listCheckbox.size();l++)
                       {                    
 CheckBox edtCheckbox = (CheckBox)llremo.findViewById(l);
         boolean checked=edtCheckbox.isChecked();
                           if (checked)
                           {  
                               Log.i("was checked",edtCheckbox.getText().toString());
                               strchekBocname=edtCheckbox.getText().toString();
                               Log.v("strchekBocname checkbox post string", strchekBocname);
                               maparray.put("Value", strchekBocname);   
                               listaddalldatofform13formValue.add(strchekBocname);

                           }
