# 第三次实验
掌握在Android应用中使用图片等资源的方法。
## 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

1 统一步骤：

## 4. 实验体会
1 在对Activity布局进行编写时，由于要对控件进行布局，之前所采用的ConstraintLayout布局方式需要更改为相对布局Relativelayout，这样可让控件自由设置;
2 在写Activity时，通过监听在xml定义的按钮，在运用Intent来启动另一个Activity。
