I am new to Android Studio. Following the tutorial given by developer.android I have created a new project. They asked to create a blank activity and as there is no one such, I have used Empty Activity as the template. Then the tutorial said that there will be a content_main.xml inside res/layout folder, but I didn't find one. Did I build the correct Application? What probably may be the wrong? Thanks in advance.

推荐答案

content_main.xml文件.默认情况下，此活动将在屏幕底部具有浮动按钮.

content_main.xml file will be generated when you choose "blank activity" . This activity will be having floating button by default at the bottom of the screen.

但是，当您选择空活动"时，不会生成content_main.xml，也不会具有浮动按钮，而只是简单的活动.

But when you choose "empty activty" then content_main.xml won't be generated and it won't be having floating button , but just simple activity.

因此，为您的教程选择空白活动"，然后您的教程将运行正常

So for your tutorial choose "blank activity" and then your tutorial will run fine
