ContourPlot[Cos[x*y]/Exp[x^2 + y^2], {x, -2, 2}, {y, -2, 2},
 ContourLabels -> (Text[
     If[FreeQ[{0.2, 0.4, 0.6, 0.8}, #3], #3], {#1, #2}] &),
 Contours -> 9]

It's weird that below doesn't work in my computer=EF=BC=9A
ContourPlot[Cos[x*y]/Exp[x^2 + y^2], {x, -2, 2}, {y, -2, 2},
 ContourLabels -> (Text[
     If[MemberQ[{0.1, 0.3, 0.5, 0.7, 0.9}, #3], #3], {#1, #2}] &),
 Contours -> 9]

Even

ContourPlot[Cos[x*y]/Exp[x^2 + y^2], {x, -2, 2}, {y, -2, 2},
 ContourLabels -> (Text[
     If[MemberQ[{0.1, 0.3, 0.5, 0.7, 0.9}, #3], #3], {#1, #2}] &),
 Contours -> Table[0.1 i, {i, 1, 9}]]

doesn't work either. Are you ok with this?
