ArcProgressBar

Arc ProgressBar Configurable 圆弧环形进度条

DEMO

Attributes

name	format	description
borderWidth	integer	圆弧边框的宽度
progressStyle	tick/arc	进度条类型，tick为带刻度的
radius	integer	半径
arcbgColor	color	圆弧的边框背景
degree	integer	弧度，设置为0即为圆形进度条，180为半圆
tickWidth	integer	刻度的宽度
tickDensity	integer	刻度的密度 2~8 越小越密
bgShow	boolean	是否显示圆弧边框背景
arcCapRound	boolean	圆弧的笔触是否为圆形，tick无效

interface

提供了绘制圆弧中间区域的一个接口

/**
   * 
   * @param canvas  
   * @param rectF  圆弧的Rect
   * @param x      圆弧的中心x
   * @param y      圆弧的中心y
   * @param storkeWidth   圆弧的边框宽度
   * @param progress      当前进度
   */
public interface  OnCenterDraw {
  public  void draw(Canvas canvas, RectF rectF, float x, float y,float storkeWidth,int progress);
}

默认提供了两个实现 onImageCenter

OnTextCenter

Use

    <com.czp.library.ArcProgress
        android:id="@+id/myProgress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:degree="0"
        app:progressStyle="arc" />

    <com.czp.library.ArcProgress
        android:id="@+id/myProgress01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/myProgress"
        app:radius="80dp"
        app:progressColor="@color/progressColor"
        app:tickDensity="3" />

    <com.czp.library.ArcProgress
        android:id="@+id/myProgress02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/myProgress"
        app:radius="90dp"
        app:arcCapRound="true"
        app:degree="180"
        app:progressStyle="arc"
        app:progressColor="@color/progressColorBlue"
        app:tickDensity="3" />

 mProgress.setOnCenterDraw(new ArcProgress.OnCenterDraw() {
            @Override
            public void draw(Canvas canvas, RectF rectF, float x, float y, float storkeWidth,int progress) {
                Paint textPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
                textPaint.setStrokeWidth(35);
                textPaint.setColor(getResources().getColor(R.color.textColor));
                String progressStr = String.valueOf(progress+"%");
                float textX = x-(textPaint.measureText(progressStr)/2);
                float textY = y-((textPaint.descent()+textPaint.ascent())/2);
                canvas.drawText(progressStr,textX,textY,textPaint);
            }
        });
