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
