一、提出任务
二、涉及知识点
三、完成任务
（一）创建安卓项目
基于Empty Activity创建安卓项目 - StudentManagement
单击【Finish】按钮
将MainActivity改名为SplashScreenActivity
将对应的布局文件activity_main.xml改名为activity_splash_screen.xml
（二）准备图片资源
准备三张图片，拷贝到mipmap目录里
（三）创建启动界面
1、启动界面布局资源文件
布局资源文件 - activity_splash_screen.xml

有两处报错，需要我们在字符串资源文件文理定义两个字符串变量
2、编辑字符串资源文件
字符串资源文件 - strings.xml
<resources>
<string name="app_name">学生信息管理系统V1.0</string>
<string name="title">学生信息管理系统</string>
<string name="version">Version 1.0</string>
</resources>
复制代码
3、创建动画资源文件
在res目录里创建anim子目录，在子目录里创建自定义动画资源文件animator.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<alpha
android:duration="3000"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
<rotate
android:duration="3000"
android:fromDegrees="0"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="+360" />
</set>
复制代码
4、编写启动界面类
启动界面类 - SplashScreenActivity

目前，程序会报错，因为登录界面LoginActivity尚未创建
在net.huawei.student_management包里创建ui子包
将启动界面类拖进ui子包
暂时创建一个空的登录界面，这样我们就可以测试启动界面运行效果
在ui子包里基于模板创建登录界面 - LoginActivity
单击【Finish】按钮
查看安卓项目清单文件
5、启动应用，查看效果
启动界面有动画，经过4秒自动跳转到登录界面
