A simple way to "badge" any given Android view at runtime without having to cater for it in layout.

Note: If your aim is to replicate the iOS icon and TabBar badge UI for notifications, consider using Android UI conventions such as the number field of the Notification class rather than this method.

Simple example:

View target = findViewById(R.id.target_view);
BadgeView badge = new BadgeView(this, target);
badge.setText("1");
badge.show();

This project contains a fully working example application. Refer to the DemoActivity class for more custom badge examples, including custom backgrounds and animations. BadgeView is a subclass of TextView so you can use all of TextView's methods to style the appearance of your badge.

To use ViewBadger in your own Android project, simply copy android-viewbadger.jar (available from this repository's package downloads) into your project's /libs directory and add it to the build path.
