项目中用到这种自定义的进度条，把代码提取出来，方便以后查找继续使用，哈哈。
效果图：
底部文字需要绘制圆角背景，需要用到drawRoundRect()，该方法用于在画布上绘制圆角矩形，通过指定RectF对象以及圆角半径来实现。该方法是绘制圆角矩形的主要方法，同时也可以通过设置画笔的空心效果来绘制空心的圆角矩形。
【基本语法】public void drawRoundRect (RectF rect, float rx, float ry, Paint paint)
参数说明
rect：RectF对象。
rx：x方向上的圆角半径。
ry：y方向上的圆角半径。
paint：绘制时所使用的画笔。
自定义view的类CircleProgressView：
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
float centerX = getWidth() / 2;
float centerY = getHeight() / 2;
radius = centerX-stokeWidth/2;
canvas.drawCircle(centerX, centerY, radius, mCirPaint);
//画圆
RectF rectF=new RectF(centerX - radius, centerY - radius, centerX + radius, centerY + radius);
canvas.drawArc(rectF, -90, progress * 360 / 100, false, mArcPaint);
//设置中心文本
if (null != centerText) {
canvas.drawText(centerText, centerX - (mTextCenterPaint.measureText(centerText)) / 2, centerY + mTextCenterSize / 2, mTextCenterPaint);
}
//上方文字
if (null != topText) {
canvas.drawText(topText, centerX - (mTextTopPaint.measureText(topText)) / 2, centerY - mTextCenterSize, mTextTopPaint);
}
//最上方小文字
if(null !=topFloorText){
canvas.drawText(topFloorText,getWidth()-mTextCenterPaint.measureText(topFloorText),centerY-mTextCenterSize-mTextTopSize, mTextTopFloorPaint);
}
if (null != bottomText) {
//下方圆角矩形
Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG);
paint.setAntiAlias(true);
paint.setStyle(Paint.Style.STROKE);
paint.setColor(bottomTextColor);
RectF rec = new RectF(centerX - (mTextBottomPaint.measureText(bottomText)) / 2-DensityUtil.dip2px(mContext,6),
getHeight()-centerY/2-mTextBottomSize,
centerX +(mTextBottomPaint.measureText(bottomText)) / 2+DensityUtil.dip2px(mContext,6),
getHeight()-(centerY)/2+mTextBottomSize/2);
canvas.drawRoundRect(rec,10, 10, paint); //第二个参数是x半径，第三个参数是y半径
//下方文字
canvas.drawText(bottomText,centerX - (mTextBottomPaint.measureText(bottomText)) / 2, getHeight()-(centerY)/2, mTextBottomPaint);
}
}
布局文件代码：
<com.mylibrary.CircleProgressView
android:layout_width="160dp"
android:layout_height="160dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:id="@+id/progress_view"
app:unReachColor="@color/unReachColor"
app:reachColor="@color/blue"
app:topFloorTextColor="@color/colorAccent"
app:bottomTextColor="@color/blue"
app:centerTextColor="@color/blue"
app:stokeWith="20"
app:topFloorTextSize="10"
app:topTextSize="14"
app:centerTextSize="30"
app:bottomTextSize="14"
/>
activity中设置progress相关属性
circleProgressView= (CircleProgressView) findViewById(R.id.progress_view);
circleProgressView.setTopFloorText("小文字");
circleProgressView.setTopText("上方文字");
circleProgressView.setCenterText("中间文字");
circleProgressView.setBottomText("下方文字");
circleProgressView.setProgress(80);
circleProgressView.setSpeed(40);
以后会继续添加。源码地址：https://github.com/yinsujun/CircularProgress
