+# 第三次实验
+
+## 1.实验目标
+
+（1）在界面上显示至少一张图片（按照自己的题目添加）；
+（2）提交res/drawable及图片使用的代码；
+（3）提交res/values, res/layout等其他代码；
+（4）将应用运行结果截图，放到实验报告中；
+（5）点击图片（或按钮）时，打开另一个Activity。
+
+## 2.实验步骤
+
+统一步骤：
+https://github.com/hzuapps/android-labs-2018/blob/master/labs-steps.md
+Android 在TextView 中显示图片的4种方式：
+https://blog.csdn.net/u012724237/article/details/79010741
+
+## 3.实验结果
+
+![image](https://github.com/Susie-Lau/android-labs-2018/blob/master/com1614080901125/%233/res/drawable/cower.png?raw=true)

+
+## 4.实验心得
+此次实验虽然只是考验插入图片，但实际上在进行代码操作的时候，由于对java语言的不熟练，导致花费了很多时间去寻找和修改错误，因此，还是需要好好巩固知识。

+# 第四次实验
+
+## 实验目的
+ 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！）
+
+## 实验内容
+
+ 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；
+
+## 实验结果
+
+![](https://github.com/Susie-Lau/android-labs-2018/blob/master/com1614080901125/%234/res/drawable/text4.png)
+
+## 实验体会
+
+这次实验主要是考验我们对于界面布局的设计，由于电脑无法运行虚拟机，所以只能截图，在这次实验中，接触到的知识点比较多，比如如何去设置按钮的大小，类型，排列等等，步骤虽然比较冗杂，但是效果可以很快看见，也可以随时修改。
