I have three Activities. how to change the theme of only one of them?

I use this in an old app. Don't know if it works yet. Put the lines in the manifest:

SetActivityAttribute(mymodule1, android:theme, @style/Theme.Transparent)
SetActivityAttribute(mymodule2, android:theme, "@android:style/Theme.Holo.Light")

Thank you for your response, I have tried it and it works, however, It couldn't find "@style/Theme.Transparent", but it has nothing to do with my app.​
