android Badge 참고사항(카운트)

Look at my answer here for widgets/app.

You can use shapecount.xml

res/layout/tabicon.xml

<RelativeLayout

    android:orientation="vertical"

    android:background="@null"

    android:id="@+id/rlayout"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content" >

    <ImageView 

            android:id="@+id/icon"

            android:src="@android:drawable/ic_menu_mylocation" <!-- Just for test -->

            android:layout_margin="0dp"

            android:layout_height="wrap_content" 

            android:layout_width="wrap_content"/>


    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"

        android:text="50" android:textSize="12dp" android:textStyle="bold"  

        android:background="@drawable/shapecount"

        android:textColor="#FFFFFF"

        android:paddingLeft="3dp" android:paddingRight="3dp"

            android:layout_margin="0dp"

        android:layout_alignBottom="@+id/rlayout"

        android:id="@+id/txtCount" />


</RelativeLayout>

When creating your tab:

LayoutInflater inflater = LayoutInflater.from(this);

View view = inflater.inflate(R.layout.tabicon, null);

final TextView txtCount = (TextView) view.findViewById(R.id.txtCount);


spec = tabHost.newTabSpec("artists").setIndicator(view).setContent(intent);

Now you can use txtCount to update the number in the tab's icon. See the post I pointed out above for an example of TimerTask to test this.

You will have to arrange the layout as you wish also
