开始学习JAVA语言并进行一些andriod程序的开发，但是发现Google有将androidstudio来代替eclipse成为开发者首选的IDE的趋势。果断放弃eclipse,于是就在androidstudio上进行简单的入门操作。进行自我学习与提高，仅供参考。

1.打开Androidstudio，选择file-->New-->NewProject来创建新的工程。如图1

2.创建新的项目以后，出现下图，可以在Applicationname中输入程序的名称，这里我没有修改它提供的“MyApplication”,然后点击“NEXT”运行下一步。如图2

3.会出现Phone andTablet界面（手机和平板）以及最小的SDK界面。选中并点击“next“运行下一步。如图3

4.接下来选择不同的模板，我选择"EmptyActivity"空界面,双击进入即可。如图4

5.输入ActivityName,以及layout name（布局名称）点击“Finish”进入。如图5

6.创建activity成功后，再次点击File-->New-->JavaClass。如图6

7.然后出现新的类名。我输入“Helloworld”。点击OK.如图7

8.出现下列界面，然后开始编写自己的程序，我将最简单的程序helloworld的模板放进去。如图8
