<Button android:background="@android:color/transparent"

 android:text="@+id/Button01"

 android:id="@+id/Button01"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:textColor="#ffffff" />

<Button android:background="@android:color/transparent"

 android:text="@+id/Button01"

 android:id="@+id/Button01"

 android:layout_width="wrap_content"
