实验四 Android程序设计-1
Android Stuidio的安装测试: 参考《Java和Android开发学习指南(第二版)(EPUBIT,Java for Android 2nd)》第二十四章:
安装 Android Stuidio
完成Hello World, 要求修改res目录中的内容,Hello World后要显示自己的学号,提交代码运行截图和码云
-Git链接,截图没有学号要扣分学习Android Stuidio调试应用程序
实验四 Android程序设计-2
Activity测试: 参考《Java和Android开发学习指南(第二版)(EPUBIT,Java for Android 2nd)》第二十五章:
构建项目,运行教材相关代码
创建 ThirdActivity, 在ThirdActivity中显示自己的学号,修改代码让MainActivity启动ThirdActivity

实验四 Android程序设计-3
UI测试: 参考《Java和Android开发学习指南(第二版)(EPUBIT,Java for Android 2nd)》第二十六章:
构建项目,运行教材相关代码
修改代码让Toast消息中显示自己的学号信息
MainActivity.java主要代码
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnshow1=(Button) findViewById(R.id.btn1);
btnshow1.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v){
Toast toast = Toast.makeText(MainActivity.this,"20155212江振思", Toast.LENGTH_LONG);
toast.show();
}
});
}
