for me view 2 and 3 are getting black work space
The default background in a Design Model when the Display Style for the Active View is Wireframe is black. You will find more on this in the application help > Getting Started topic.
Please note that you have a choice to use local or online help documents. This can be chosen from the File tab > Settings > User > Preferences > Help Settings. You may find local help is currently faster when reading through a long series of topics.

can send me steps to put those view 2 and 3 to be same as view 1
You can change the display style for View 1 to Wireframe or a range of other presentations via the View Attributes dialog as described under Help topic > Getting Started > Viewing Designs.
You can use the Copy View command to duplicate View 1 to any other view(s).
