1. It is a mistake to set targetSdkVersion to 28. For now you should set it to 26.

2. Assuming that you are using a recent version of B4A then you should set the theme like this:

CreateResourceFromFile(Macro, Themes.LightTheme)

3. Make sure that all labels and EditText views use the default color for the TextColor. You can delete the color value to switch to the default color.

You don't need this line:

SetApplicationAttribute(android:theme, "@style/LightTheme")

The default color should look "fine" and change based on the set theme. It is possible that the default color will be grey and not black.

You can use similar code to change the text color (if you don't want to do it manually with the designer).
