Badge view is a view group providing to show a badge(or with a text) at four-corner(top-left, top-right, etc.)
Currently, it only supports one child(children) just like the framework' s android.widget.ScrollView.
This is what I learn how to write your customized view group and use it in your practice project. So, if you have any trouble or suggestion, feel free to drop me a line.

- via xml-layout(don' t forget to add app as xmlns)
<org.heisenberglab.badge.BadgeView
xmlns:app="http://schemas.android.com/apk/res-auto"
app:show_badge="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:padding="4dp"
android:text="Hello, World!"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</org.heisenberglab.badge.BadgeView>- via java code
FrameLayout container = (FrameLayout) findViewById(R.id.container);
// NOTE: the child view must use the same layout-params with the badge!
ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT
);
BadgeView badgeView = new BadgeView(this);
badgeView.setLayoutParams(lp);
TextView tv = new TextView(this);
tv.setLayoutParams(lp);
tv.setText("This\n is \n a \n tall \n text:-)");
badgeView.addBadgeView(tv);
badgeView.showBadge("...");
badgeView.setBadgeLocation(BadgeView.BadgeLocation.BOTTOM_LEFT);
// add to the container
container.addView(badgeView);To see the default value, take a look at the source code, it' s really a simple one.
<declare-styleable name="BadgeView">
<attr name="badge_color" format="color" />
<attr name="badge_text" format="string" />
<attr name="badge_text_color" format="color" />
<attr name="badge_text_size" format="dimension" />
<attr name="normal_badge_radius" format="dimension" />
<attr name="small_badge_radius" format="dimension" />
<attr name="badge_margin" format="dimension" />
<attr name="show_badge" format="boolean" />
<attr name="show_text_badge" format="boolean" />
<attr name="badge_location" format="enum">
<enum name="top_left" value="0" />
<enum name="top_right" value="1" />
<enum name="bottom_left" value="2" />
<enum name="bottom_right" value="3" />
</attr>
</declare-styleable>-
it only supports one child(children), like it said before.

the lib hasn' t published to maven central, so you must clone the lib add add it to your gradle-styled
build.xmlas a dependency now. -
the badge view simply uses the child(ren)' s width and height as its dimension. So you must specify it either use xml-layout or java code. This inconvenience would be fixed in the next version:-)

required android 2.2+ (API level 8). Maybe it could support start at Android 1.0, but it deserves nothing...
