调用listview对象的setonitemclicklistener()方法，设置条目的点击事件，参数：onitemclicklistener对象

使用匿名内部类实现，重写onclick()方法，传递进来的参数：listview，当前view，position,id

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

把电话放在edittext上，当点击下一步的时候保存到sp中
