问题 My app at Play Store does not have any localizations other than the default: English (United States) . This time I created a new apk to update it. And it uses android-support-v7-appcompat library. So when I uploaded the new apk and in the apk details it says 'added 72 new localizations'. These are coming from the values folders in android-support-v7-appcompat (values-af, values-am,...etc).

As I'm using dark colored ToolBar I would like to show the text and back home

问题 I'm using support v7's toolbar. I added a custom view, but the custom view doesn't seem to obey "match_parent". It would only stretch as far as the first icon it sees. Does anyone know a fix to this? Or is the toolbar not meant to be used this way?

问题 I am having some trouble setting the sub-title in my Toolbar from my fragment.
