Android Icons: Home screen and application menu

Question

On my Samsung Galaxy, application icons displayed on my Home screen often do not match those displayed on the application menu.

Firstly, I want to know that this is typical for Samsung / Galaxy (or some subset of Android phones), or if it is across the platform? Secondly, I would like to know how to install this in my Android project.

To illustrate what I ask, refer to the following image:

Icons 1 and 2 are typical for many third-party applications: the icon is transparent on the main screen, but in the application menu the icon is overloaded with a graphic button. On my phone, the latter is more often than not a dirty green, radial image.

However, some applications overloaded this behavior: icons 3 and 4 show that MapQuest was able to specify a different base color for the button (the same radial pattern); and icons 5 and 6 show what seems like a complete replacement for the image of a button or application menu icon.

Can someone explain what I need to do to specify both forms of the icon in my project?

Thanks in advance.

Answer 1

This particular effect is part of the Samsung Homescreen user interface. He does something similar on galactic tablets.

icons 3 and 4 show that MapQuest was able to specify a different base color for the button

I don’t think that they indicated that I believe that this is either luck in the draw (on the Galaxy Tab there are many colors blue, green, orange, pinkish, etc .... they do not seem to have the type of pattern for which icons get what color), or he can say that their icon is also green, and because of this, it changes colors, so you don’t get a green icon on top of a green background.

and icons 5 and 6 indicate that it appears to be a complete replacement for the image of a button or application menu icon.

I do not think they controlled it. I think this is just another of the possible backgrounds that the system uses.

Can someone explain what I need to do to specify both forms of the icon in my project?

As far as I know, you cannot use backgrounds for the third part home replacement / launch application. In this case, Samsung (but there are other replacements for the home and launcher on the market that can also use this effect if they want to.)

Answer 2

Thank you Tim - further play around showed more ...

As a result of refactoring the names of my packages, I ended up with two copies of my application (with identical icons) in my application.

As Tim suggested, the second icon has a different, apparently randomly selected background. Apparently, the button color is not related to any color on my icon, however, since the same icon got a highlighted background.
