推荐答案

创建共享preference：

SharedPreferences sp=getSharedPreferences("Login", 0);
SharedPreferences.Editor Ed=sp.edit();
Ed.putString("Unm",Value );              
Ed.putString("Psw",Value);   
Ed.commit();

从分享preference获得值：

SharedPreferences sp1=this.getSharedPreferences("Login",null);

String unm=sp1.getString("Unm", null);       
String pass = sp1.getString("Psw", null);
