Android 技术总结（020）—— level-list的使用

1、资源文件。

level_credit_rating.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<level-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:drawable="@drawable/icon_seller_credit_level_first1"
        android:maxLevel="1"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_first2"
        android:maxLevel="2"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_first3"
        android:maxLevel="3"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_first4"
        android:maxLevel="4"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_first5"
        android:maxLevel="5"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_second1"
        android:maxLevel="6"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_second2"
        android:maxLevel="7"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_second3"
        android:maxLevel="8"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_second4"
        android:maxLevel="9"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_second5"
        android:maxLevel="10"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_third1"
        android:maxLevel="11"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_third2"
        android:maxLevel="12"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_third3"
        android:maxLevel="13"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_third4"
        android:maxLevel="14"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_first5"
        android:maxLevel="15"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_fourth1"
        android:maxLevel="16"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_fourth2"
        android:maxLevel="17"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_fourth3"
        android:maxLevel="18"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_fourth4"
        android:maxLevel="19"/>
    <item
        android:drawable="@drawable/icon_seller_credit_level_fourth5"
        android:maxLevel="20"/>

</level-list>

2、在布局文件中使用。
[html]
<ImageView
           android:id="@+id/rating"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_alignParentRight="true"
           android:layout_marginRight="50dp"
           android:layout_marginTop="6dip"
           android:src="@drawable/level_credit_rating" />

3、在代码中使用。
[java] view plaincopy
holder.rating.setImageLevel(record.getCreditRating());
