Percentage Chart View
项目简介
一个多样式百分比进度条实现库,包括环,饼,填充式
功能演示
RING MODE
PIE MODE
FILL MODE
集成说明
方式一
- 下载PercentageChartView的har包PercentageChartView.har(位于output文件夹下)。
- 启动DevEco Studio,将下载的har包,导入工程目录“entry->libs”下。
- 在moudle级别下的build.gradle文件中添加依赖,在dependences标签中增加对libs目录下har包的应用。
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar', '*.har']) implementation project(':PercentageChartView') …… }
-
在导入的har包上点击右键,选择“Add as Library”对包进行引用,选择需要引用的模块,并点击“OK”即引用成功。
方式二
在module的build.gradle中添加对PercentageChartView
的依赖
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
……
implementation 'com.gitee.archermind-ti:PercentageChartView:1.0.0-beta'
}
,在project的build.gradle中添加mavenCentral()的引用
allprojects {
repositories {
……
mavenCentral()
}
}
使用说明:
<com.ramijemli.percentagechartview.PercentageChartView
ohos:id="@+id/view_id"
ohos:layout_width="match_parent"
ohos:layout_height="match_parent"
app:pcv_mode="pie"
app:pcv_orientation="counter_clockwise"
app:pcv_animDuration="800"
app:pcv_animInterpolator="anticipate_overshoot"
app:pcv_progress="10"
app:pcv_startAngle="90"/>

流程使用
除了pcv_mode属性(目前),所有XML属性都有对应的Java属性。
可以通过进行更改和调用apply()来设置更新。这将确保重新绘制视图
mChart.textColor(Color.BLACK)
.textSize(sizeSp)
.typeface(typeface)
.textShadow(Color.WHITE, 2f, 2f, 2f)
.progressColor(Color.RED)
.backgroundColor(Color.BLACK)
.apply();
对于单个更新,可以调用所需的setter方法。例如setTextSize (sizeSp)
。
进度条基本的自适应颜色
要使用每个进度的颜色特性,你必须使用**setAdaptiveColorProvider()
方法传递一个AdaptiveColorProvider
**类。 自适应颜色可以应用于进度、背景、文本和背景栏。 值得一提的是,梯度颜色的优先级高于所提供的颜色,您可以忽略重新定义不需要的方法,因为它们默认有一个实现。
AdaptiveColorProvider colorProvider = new AdaptiveColorProvider() {
@Override
public int provideProgressColor(float progress) {
if (progress <= 25)
return colorOne;
else if (progress <= 50)
return colorTwo;
else if (progress <= 75)
return colorThree;
else return colorFour;
}
@Override
public int provideBackgroundColor(float progress) {
//This will provide a bg color that is 80% darker than progress color.
return ColorUtils.blendARGB(provideProgressColor(progress), Color.BLACK, .8f);
}
@Override
public int provideTextColor(float progress) {
return provideProgressColor(progress);
}
@Override
public int provideBackgroundBarColor(float progress) {
return ColorUtils.blendARGB(provideProgressColor(progress), Color.BLACK, .5f);
}
};
mPieChart.setAdaptiveColorProvider(colorProvider);
进度改变监听
可以通过设置一个**OnProgressChangeListener
**来获得进度更新。
chart.setOnProgressChangeListener(new PercentageChartView.OnProgressChangeListener() {
@Override
public void onProgressChanged(float progress) {
Log.d(TAG, String.valueOf(progress));
}
});
文本格式化
对于文本,可以使用其他单位代替百分比。你必须使用**setTextFormatter()
方法传递一个ProgressTextFormatter
**类。< br / >
mRingChart.setTextFormatter(new ProgressTextFormatter() {
@Override
public String provideFormattedText(float progress) {
int days = (int) (progress * maxDays / 100);
return days + " days";
}
});
