# 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
```groovy
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
``` groovy
allprojects {
repositories {
……
mavenCentral()
}
}
```

| `pcv_gradientAngle` | `integer` | `pcv_startAngle` | All | Sets linear gradient colors' drawing angle to **\[0..360]**. |
#### 开始角度
`pcv_startAngle` 和 `pcv_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";
}
});
```
