+#第四次实验
+
+## 1.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。（不要做登录注册！） 
+
+## 2.实验要求
+
+1.使用其中一种布局方式，设计所选题目的界面；  
+
+2.通过控件ID获取界面对象，执行相关操作；
+
+3.实现界面控件的事件处理，例如点击按钮；
+
+ ## 3.实验步骤
+
+1.首先设计出想要写出的界面雏形。
+
+2.再根据布局往xml中添加控件。
+
+3.通过代码处添加layout布局或可视化界面处移动控件来实现具体布局。
+
+## 4. 实验结果

+
+     这次实验提高了我的应用程序界面设计的能力，首先要为自己所想要建造的APP选择合适的界面布局，我选择LinearLayout线型。LinearLayout布局容器内的组件一个挨着一个地排列起来：可以控制个组件横向排列，也可控制各组件纵向排列。通过orientation属性设置线性排列的方向是垂直(vertical)还是纵向(horizontal)。 
+然后通过控件按钮来监测界面对象，实现相关跳转。
