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

  1. 下载PercentageChartView的har包PercentageChartView.har(位于output文件夹下)。
  2. 启动DevEco Studio,将下载的har包,导入工程目录“entry->libs”下。
  3. 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')
	……
}

4.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

  1. 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'
    }
  2. 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"/>

Attributes

Name Format Default Supported modes Description

pcv_startAnglepcv_gradientAngle 属性接受下一个插图的值。

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";  
    }  
});
