在android应用中，制作包不会导入

Question

when I pasted the import statements in android studio, they are not importing. I mean when I pasted just like a flash they are disappearing.

Answer 1

Use a instance or a member from the imported class first, then import the class. I don't know why it does this, probably to avoid imports that are not needed. Also you may notice that some classes are imported automatically when you use the class , GLSurfaceView for example.
