[操作系统][android] 手机卫士保存安全号码


 

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
