android 自定义圆形进度条拖动样式 android自定义圆形进度条

首先在布局文件定义Progressbar

xmlns:android="/apk/res/android"

xmlns:tools="/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="com.christmas.circleprogressbar.MainActivity">

android:id="@+id/pb_count_down_bottom"

style="?android:attr/progressBarStyleHorizontal"

android:layout_width="50dp"

android:layout_height="50dp"

android:layout_below="@+id/fl_count_down_middle"

android:layout_centerHorizontal="true"

android:layout_marginTop="30dp"

android:progressDrawable="@drawable/circle_progress_bar"

tools:max="100"

tools:progress="50" />

然后定义progressDrawable文件

android:fromDegrees="270"

android:toDegrees="270">

android:innerRadiusRatio="2.5"

android:shape="ring"

android:thickness="2dp"

android:useLevel="true">

android:angle="0"

android:endColor="#4285f4"

android:startColor="#4285f4"

android:type="sweep"

android:useLevel="false" />
