Android Question Implicit string to integer question

[johnf2013]

colorMap keys are color codes and the values are color strings.

The following code does not work;

colorSettings.AddList2("Background","Plot background",colorMap.Get(prefManager.GetString("Background")),defGridBkgColor,"",colorMap)

This code does work;

Dim x As Int
x = prefManager.GetString("Background")
colorSettings.AddList2("Background","Plot background",colorMap.Get(x),defGridBkgColor,"",colorMap)

In the first case I would have expected an implicit conversion from string to integer in the .Get method.
In practice the conversion fails and so the key is not found.

In the second case I force the implicit conversion from string to integer and the key lookup succeeds.

Why would this be so?

Map.Get method expects an Object. The compiler cannot know that your keys are integers.

Ok, makes sense. I am a C/C++ programmer making a foray into Basic. I would just cast it. What do I do in Basic?

What do I do in Basic?

The programming language is named B4X.

You cast it with:

Dim x As Int = prefManager.GetString("Background")
colorSettings.AddList2("Background","Plot background",colorMap.Get(x),defGridBkgColor,"",colorMap)

Ok thanks for your help.
B4X it is from now on!!!
