Have a look at custom rating in motorola http://community.developer.motorola.com/t5/Android-App-Development-for/custom-rating-bar-style-using-android-s-ratingBar-small-style/td-p/10462
更新
styles.xml
这必须位于您的值文件夹中
This must be located in your values folder
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="foodRatingBar" parent="@android:style/Widget.RatingBar">
<item name="android:progressDrawable">@drawable/food_rating_bar_full</item>
<item name="android:minHeight">23dip</item>
<item name="android:maxHeight">25dip</item>
</style>
</resources>
food_rating_bar_full.xml
food_rating_bar_full.xml
此文件必须在 Drawable 文件夹中.
This file must be in Drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/background"
android:drawable="@drawable/food_ratingbar_full_empty" />
<item android:id="@+id/secondaryProgress"
android:drawable="@drawable/food_ratingbar_full_empty" />
<item android:id="@+id/progress"
android:drawable="@drawable/food_ratingbar_full_filled" />
</layer-list>
food_ratingbar_full_empty.xml
food_ratingbar_full_empty.xml
此文件必须在 Drawable 文件夹中.
This file must be inside Drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<!-- This is the rating bar drawable that is used to
show a filled cookie. -->
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="@drawable/cookiee" />
<item android:state_focused="true"
android:state_window_focused="true"
android:drawable="@drawable/cookiee" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="@drawable/cookiee" />
<item android:drawable="@drawable/cookiee" />
</selector>
food_ratingbar_full_filled.xml
food_ratingbar_full_filled.xml
此文件必须位于 Drawable 文件夹中.
This file must be located in Drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<!-- This is the rating bar drawable that is used to
show a unfilled cookie. -->
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="@drawable/cookie" />
<item android:state_focused="true"
android:state_window_focused="true"
android:drawable="@drawable/cookie" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="@drawable/cookie" />
<item android:drawable="@drawable/cookie" />
</selector>
main.xml 文件应如下所示:
main.xml file should look like :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RatingBar android:id="@+id/ratingBar1"
style="@style/foodRatingBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RatingBar>
</LinearLayout>
MainActivity.class 应该如下所示:
MainActivity.class should look like :
import android.app.Activity;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.RatingBar.OnRatingBarChangeListener;
import android.widget.Toast;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
RatingBar rb;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
rb=(RatingBar)findViewById(R.id.ratingBar1);
rb.setOnRatingBarChangeListener(new OnRatingBarChangeListener(){
@Override
public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromUser) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),Float.toString(rating),Toast.LENGTH_LONG).show();
}
});
}
}
我使用了两张图片:
cookie.jpg
cookie.jpg
这两张图片大小相同,一张用于识别选中的Rating Bar,另一张用于识别未选中的RatingBar
This two images are of same size one is used for identifying selected Rating Bar and other for identifying unselected RatingBar
