Membuat Ratingbar android

kali ini kita akan membuat ratingbar, biasanya digunakan untuk input suatu penilaian
yang perlu diketahui dari properti file xmlnya, lihat pada property Ratingbar


numStars :menentukan jumlah bintang
stepsize: menetukan nilai setiap bintang
Rating :menentukan nilai awal bintang yang tepilih pada saat awal program di eksekusi

ok karena saya malas membuat kodenya kode ini saya ambil dari  http://www.mkyong.com/android/android-rating-bar-example/
file xmlnya

[code language="java"]

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView
