我有一个进度drawable,它在运行Android Lollipop的设备上无法正常工作.

关于M的截图

Lollipop上的截图

circle_percentage_drawable.xml

android:fromDegrees="270"

android:pivotX="50%"

android:pivotY="50%"

android:toDegrees="270">

android:innerRadiusRatio="2.5"

android:shape="ring"

android:thicknessRatio="25.0">

android:centerColor="@android:color/holo_red_dark"

android:endColor="@android:color/holo_red_dark"

android:startColor="@android:color/holo_red_dark"

android:type="sweep"/>

android:fromDegrees="270"

android:pivotX="50%"

android:pivotY="50%"

android:toDegrees="270">

android:innerRadiusRatio="2.5"

android:shape="ring"

android:thicknessRatio="25.0">

android:centerColor="@android:color/holo_red_dark"

android:endColor="@android:color/holo_red_dark"

android:startColor="@android:color/holo_red_dark"

android:type="sweep"/>

这个drawable用作ProgressView的背景,如下所示：

android:id="@+id/circle_progress"

style="?android:attr/progressBarStyleHorizontal"

android:layout_width="70dp"

android:layout_height="70dp"

android:gravity="center"

android:progress="65"

android:indeterminate="false"

android:progressDrawable="@drawable/circle_percentage_drawable"

/>

渲染为65％的圆圈显示在运行Android M,KitKat,Jellybean的设备上.但是,如果在Android Lollipop(API 21)上运行相同的代码,则该圈显示为100％.

解决方法:

在循环进度条xml中添加android：useLevel = true“

android:useLevel="true">

android:fromDegrees="270"

android:pivotX="50%"

android:pivotY="50%"

android:toDegrees="270">

android:innerRadiusRatio="2.5"

android:shape="ring"

android:thicknessRatio="25.0"

android:useLevel="true">

android:centerColor="@android:color/holo_red_dark"

android:endColor="@android:color/holo_red_dark"

android:startColor="@android:color/holo_red_dark"

android:type="sweep"/>

android:fromDegrees="270"

android:pivotX="50%"

android:pivotY="50%"

android:toDegrees="270">

android:innerRadiusRatio="2.5"

android:shape="ring"

android:thicknessRatio="25.0"

android:useLevel="true">

android:centerColor="@android:color/holo_red_dark"

android:endColor="@android:color/holo_red_dark"

android:startColor="@android:color/holo_red_dark"

android:type="sweep"/>
