我想从列表视图中的列表视图中获取选中的单选按钮，如下图所示。

enter image description here

AttendanceView.class

package com.cfms.ApplicationLayer;

            }
        });
        return view;
    }


    @Override

        // TODO Auto-generated method stub

    }

              TextView txt;
              RadioGroup radiogroup;

             }


        }

我想得到完全在场，缺席和半天的员工。

请帮忙。感谢。

只需更改适配器类就解决了问题。

public void onRadioButtonClick(View v) {
    RadioButton rb = (RadioButton) v;
    Toast.makeText(getApplicationContext(),
    rb.getText(),Toast.LENGTH_SHORT).show();
    View Rg = (View) rb.getParent();
    View LLayout = (View) Rg.getParent();
    TextView txtLvId = (TextView) LLayout.findViewById(R.id.ins_itemid);
    String LvID = txtLvId.getText().toString();
    Toast.makeText(getApplicationContext(), LvID, Toast.LENGTH_LONG).show();
}
