+# 一、实验目标
+
+1. 搭建 Android(Android Studio)开发环境;
+2. 熟悉并掌握Git与GitHub.com提交实验代码的方法。
+
+# 二、实验内容
+
+1. 搭建Android Studio环境,配置SDK;
+2. 创建一个名为Net学号Activity的java类;
+3. 安装git,熟悉git bash的命令;
+4. 上交实验相关文件
+
+# 三、实验步骤
+
+1. Fork hzuapps/android-labs-2020到自己的账号下
+2. 在自己的电脑建立本地仓库克隆android-labs-2020的内容
+3. 搭建Android Studio环境,配置SDK
+4. 创建Net1814080903139Activity的java类
+5. 利用git bash来提交相关的文件到hzuapps/android-labs-2020
+
+# 四、实验结果

+![实验一](D:\Desktop\Markdown\移动应用开发\lab1result.PNG)
+
+
+
+# 五、实验心得体会
+
+第一次使用git bash 提交文件,对于需要使用到的相关命令比较陌生。例如提交代码可以使用通配符,不用把具体的完整路径都打出来。 再有,在配置全局邮箱地址及用户名,刚开始总是把邮箱当成用户名输入,结果出错,最后再重新看了一遍提示才改正过来。

+# 一、实验目标
+
+1. 根据选题要求设计界面布局及控件使用;
+2. 布局xml及界面控制操作代码提交并截图;
+3. 将应用运行结果截图。
+
+# 二、实验内容
+
+1. 用一种布局方式设计界面;
+2. 通过控件ID获取界面对象,执行相关操作:
+
+```
+// XML
+android:id="@+id/my_button"
+// Java
+findViewById(R.id.my_button);
+```
+
+1. 实现界面控件的事件处理;
+2. 操作之后,切换到第二个界面。
+
+# 三、实验步骤
+
+1. 根据自己项目设置了Fragment界面布局
+
+ 以下是部分代码:
+
+ ```java
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ ```
+
+
+
+2. 根据选题所需的功能设置对应4个的界面文件,以time.xml为例。
+
+ ```java
+
+
+
+
+ ```
+
+3.修改MainActivity.java以及4个功能类,实现Activity跳转。
+
+4.优化背景颜色以及按键图标。
+
+```java
+android:background="@color/lightyellow"
+
+android:src="@drawable/clock"
+```

+
+# 五、实验心得体会
+
+这次实验我刚开始使用的控件是Tabhost ,后来因发现控件已经被弃用,操作起来有些困难,所以我改用了Fragment界面布局。
