<?xml version="1.0" encoding="utf-8"?> 
<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle"> 
  <corners android:radius="20dp"  />     
  <solid android:color="#ff2233" /> 
</shape>  
 
 
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> 
 
LayoutInflater inflater = LayoutInflater.from(this);  
View view = inflater.inflate(R.layout.tabicon, null); 
final TextView txtCount = (TextView) view.findViewById(R.id.txtCount);
