7. The cover as claimed in claim 1, wherein an arcuate groove is formed along the joint of the main body and the view panel.

8. The cover as claimed in claim 1, wherein the main body is made of a material selected from the group consisting of polyvinyl chloride, polyethylene terephthalate, acrylonitrile-butadiene-styrene, polycarbonate, polyimide, liquid crystal polymer, polyetherimide, polyphenylene sulfide, polysulfone, polystyrene, glycol-modified polyester, and polypropylene.

9. The cover as claimed in claim 1, wherein the view panel is made of a material selected from the group consisting of polycarbonate, polymethyl methacrylate and polystyrene.

10. A method for making a cover for a mobile device, comprising the steps of: forming a main body by injection molding, the main body having a view opening formed thereon; and forming a view panel on the main body by injection molding; wherein the view panel is received in the view opening.

11. The method for making the cover as claimed in claim 10, wherein the main body has a window frame portion, the window frame portion has an inner rim defining the view opening, the inner rim has a recessed portion, the view panel has an outer rim, the outer rim has a first projected portion injection molded in the recessed portion.

12. The method for making the cover as claimed in claim 11, wherein the inner rim of the window frame portion has a second projected portion, the second projected portion has a slanting sidewall, the outer rim of the view panel has a slope portion resisting the slanting sidewall.

13. The method for making the cover as claimed in claim 11, wherein the inner rim of the window frame portion has a groove formed thereon, which functions as a gate for forming the view panel via injection molding.

14.
