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

    </shape>

          android:shape="ring"
          android:thicknessRatio="25.0">

        android:pivotY="50%"
        android:toDegrees="270">

          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"/>

此可绘制对象用作ProgressView的背景，如下所示:

<ProgressBar
      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"
      />

在运行Android M，KitKat，Jellybean的设备上，渲染为65％的圆圈呈现出渲染.但是，如果在Android Lollipop(API 21)上运行了相同的代码，则圆圈将显示为100％.

The renders as a circle drawn to 65% show up on devices running Android M, KitKat, Jellybean. However, if the same code is run on Android Lollipop (API 21) the circle shows as 100%.

推荐答案

在循环进度条xml中添加android:useLevel=true"

Add android:useLevel=true" in your circular progressbar xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>

    <shape android:shape="oval"
           android:useLevel="true">
      <solid android:color="@color/colorTranslucentBlack"/>
    </shape>

  </item>

  <item android:id="@android:id/progress">

    <rotate
        android:fromDegrees="270"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="270">
      <shape
          android:innerRadiusRatio="2.5"
          android:shape="ring"
          android:thicknessRatio="25.0"
          android:useLevel="true">
        <gradient
            android:centerColor="@android:color/holo_red_dark"
            android:endColor="@android:color/holo_red_dark"
            android:startColor="@android:color/holo_red_dark"
            android:type="sweep"/>
      </shape>
    </rotate>

  </item>

  <item android:id="@android:id/secondaryProgress">

    <rotate
        android:fromDegrees="270"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="270">
      <shape
          android:innerRadiusRatio="2.5"
          android:shape="ring"
          android:thicknessRatio="25.0"
          android:useLevel="true">
        <gradient
            android:centerColor="@android:color/holo_red_dark"
            android:endColor="@android:color/holo_red_dark"
            android:startColor="@android:color/holo_red_dark"
            android:type="sweep"/>
      </shape>
    </rotate>

  </item>
