# 第四次实验 | ||
|
||
## 1.实验目标 | ||
根据选题要求设计界面布局及控件使用; | ||
布局xml及界面控制操作代码提交并截图; | ||
将应用运行结果截图。 | ||
|
||
## 2.实验步骤 | ||
(1)、在res.layout中的activity_2中用design拖入Layouts的LinearLayout在界面中间; | ||
(2)、在LinearLayout中添加四个按钮,并将他们的text内容改成词汇测试选项内容,由于text内容中所有字母默认 | ||
全显示大写,故在values.styles中加入代码 <item name="android:textAllCaps">false</item>; | ||
(3)、以TextView的形式加入要测试的单词, | ||
android:gravity="center_horizontal" 文字居中显示 | ||
android:text="agreement" 设置文本框内容 | ||
android:textColor="#ff5e8e" 设置文本颜色,为红色 | ||
android:textSize="33dp"; 设置文字大小 | ||
(4)、设置一个按钮next放在下面,界面基本形成; | ||
## 3.实验结果 | ||

||
## 4.实验体会 | ||
|
||
这次实验使我学会了很多新的操作,通过这次实验我对这个app的实现更加有想法了,刚开始只是在design中把按钮拖到想 | ||
要的位置,结果在虚拟机app运行后按钮全都跑到左上角了,后来就在按钮上四条线拉到四边才固定住了。 | ||
