The general problem is about the inflation of the view. This value is stored in the theme at attribute alertDialogTheme. The better approach I believe is to actually query for the selected theme for dialogs.

Hi, the code you provided does always set the same style disregarding the app selected theme.

…to this: View view = View.inflate(new ContextThemeWrapper(context, R.style.AboutDialog), R.layout.about_dialog, null) In our case, I needed to change this: View view = View.inflate(context, R.layout.about_dialog, null) There’s one more trick to getting this to work properly, and that’s to make sure you also use the same ContextThemeWrapper if you inflate a custom layout for the AlertDialog. …we now have something like this: new AlertDialog.Builder(new ContextThemeWrapper(context, R.style.AboutDialog)) So, instead of something like this: new AlertDialog.Builder(context) That part was super easy: just create an instance of ContextThemeWrapper that uses your style, and pass that to the Builder instead of the activity context. I chose to do the latter by making use of the ContextThemeWrapper class. In order to get it to use my style, I had to either not use the builder pattern, or override the theme for the associated context.
That itself is a tiny bit tricky, because of how AlertDialogs are normally constructed using a builder pattern in the case of AlertDialog, the Builder class is hardcoded to use a specific internal style by name. Then it’s just a matter of using that style when creating the AlertDialog. I just created a new style, based on the standard Theme.Dialog style that Android uses for dialogs, with an item to set the text to the color that would normally be used on an AlertDialog, like so: It seems Android needs a bit of encouragement to apply the correct style to AlertDialog text. I found the solution in a post by Shawn Castrianni, who ran into a similar issue with invisible text in a list on an AlertDialog. We’re using an AlertDialog to display information about the app, and everything works fine when the app is using the normal “dark” theme…but when I changed the app to use Theme.Light, the text on the About screen was rendered as dark grey on a black background, which made it very difficult to read. These styles are often collected into themes that can be applied to change the overall look of the activities in your app.įor example, the Android platform defines a pair of themes for apps to use: a standard dark theme (named Theme), for apps with light text on a dark background and a standard light theme (named Theme.Light) for apps with dark text on a light background. I ran into an interesting little quirk while working on the About dialog for our app.Īndroid lets you combine groups of settings into styles so you can easily apply them to various UI elements.
