动态添加复选框只显示最后一个值(Dynamically Added Checkboxes Shows Only Last Value)

动态添加复选框只显示最后一个值(Dynamically Added Checkboxes Shows Only Last Value)

这是我的代码，只导致员工列表的最后一个值

public void addCheckBoxesView() { Employee ee; CheckBox chkbox; ArrayList<Employee> employee_list= initEmployees(); for(int i =0; i<employee_list.size();i++) { ee = (Employee) employee_list.get(i); chkbox = new CheckBox(this); chkbox.setId(ee.getID()); chkbox.setText(ee.getName()); layout.addView(chkbox); } }

Here is my code that results in only last value of Employee List

public void addCheckBoxesView() { Employee ee; CheckBox chkbox; ArrayList<Employee> employee_list= initEmployees(); for(int i =0; i<employee_list.size();i++) { ee = (Employee) employee_list.get(i); chkbox = new CheckBox(this); chkbox.setId(ee.getID()); chkbox.setText(ee.getName()); layout.addView(chkbox); } }
