进度条xml如下:
<ProgressBar
android:id="@+id/progressBarCircular"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_alignTop="@id/squareView_3"
android:layout_toRightOf="@id/squareView_3"
android:layout_marginTop="-105dp"
android:layout_marginLeft="40dp"
android:indeterminate="false"
android:max="100"
android:progress="0"
android:background="@color/BlackText"
android:progressDrawable="@drawable/circular_progressbar" />
Circular_progressbar.xml如下:
<?xml version="1.0" encoding="UTF-8" ?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/background">
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="8.0">
<solid android:color="@color/DarkGrey" />
</shape>
</item>
<item android:id="@+id/progress">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thicknessRatio="12.0">
<solid android:color="@color/green" />
</shape>
</item>
</layer-list>
并设置进度:
ProgressBar pb = (ProgressBar)view.FindViewById(Resource.Id.progressBarCircular);
pb.Progress = 75;
这没有给我进度条,如下图所示,如何绘制进度条,如下图所示:
任何帮助将不胜感激。谢谢,快乐编码。
最佳答案
试试这个解决方案,我想您会得到想要的输出
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape
android:angle="0"
android:shape="ring"
android:thickness="10dp"
android:useLevel="false">
<solid android:color="#eeeeee" />
</shape>
</item>
<item android:id="@android:id/progress">
<rotate
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:angle="0"
android:shape="ring"
android:thickness="10dp"
android:useLevel="true">
<solid android:color="#81ca33" />
</shape>
</rotate>
</item>
</layer-list>
对于旋转,我将ProgressBar视图中的属性调整为:-
<ProgressBar
android:id="@+id/progressBarView"
android:layout_width="200dp"
android:layout_height="200dp"
style="?android:attr/progressBarStyleHorizontal"
android:indeterminateOnly="false"
android:rotation="-90"
android:max="100"
android:progressDrawable="@drawable/circular_progressbar" />
