根据索引位置把当前这条电话号码传回去

调用List对象的get()方法，得到Map，调用get(key)方法，得到这条电话

调用setResult()方法，返回去数据，参数：响应码，Intent对象

获取Intent对象，new出来

调用Intent对象的putExtra(key,val)，把电话放进去

调用finish()方法关闭当前页面

开启这个的activity使用的是startActivityForResult()

重写onActivityResult()方法，传递进来Intent对象

判断Intent对象是否为null

调用Intent对象的getStringExtra()方法，获取到电话号码
