说明： 实验功能：
在第一个Hello World！为标签的activity中显示good，该界面中有一个名为Next的按钮。点击Next按钮进入到第二个activity中去，第二个界面中只有1个Close按钮。当然，据网上有人将要比较安全的实现关闭程序的功能也不是挺简单的，因为android有专门的退出键返回键等。所以该Close按钮暂时没去实现它。
我的第1个activity为HelloworldActivity,第2个activity为NextActivity.
实验说明：
1. 要实现从1个activity跳到另一个activity，这需要通过intent来实现。当然我们需要在Next按钮上绑定一个按钮按下的监听器(这些好像是java中的知识，可我从没学过java，只能用到哪个地方再去学了)，一旦该按钮监听到有按键按下，则通过intent将指定的第2个activity触发，这样就完成了本次试验的功能。
2.在工程中,每一个activity都对应一个xml文件,xml文件主要是控制各控件的位置和属性的.
3. asserts目录下可以存放任何文件,res目录下也可以存放任意文件,且res下的文件会在gen目录下的R.java文件中自动生成一个全局id。
4. res目录下的values目下的strings.xml中的控件也是每个控件都在R.jar中对应一个id号。当然layout下的main.xml文件也是一样的。
(Experimental features:
In the first Hello World! For the activity of the label to display the good, the interface has a button called Next. Click the Next button to enter the second activity, the second interface is only a Close button. Of course, some people will be safer to close the program, according to online function is not very simple, and android have a dedicated exit key and return key. The Close button temporarily failed to achieve it.
I an activity for HelloworldActivity 2 activity is NextActivity.
Experiments show that:
(1) from one activity to another activity, which requires intent to achieve. Of course we need to bind on the Next button press of a button listener (like java in knowledge, but I never learned the java, and can only be used where to go to school). Once the button to listen to button is pressed,)
