Android中自定义圆环显示实时进度，仿里程进度

Android实现圆环进度条，显示出来实时进度

废话不多说，直接上效果图，普通的圆环进度条颜色是渐变，，这个是分段的颜色并且还要加刻度，下面看代码

白点是实时进度，自定义画上，并且保持实时进度
计算实时进度，白点所占位置

canvas.save();
        paint_2.setStyle(Paint.Style.STROKE);
        int sweep;
        if (currentNum <= maxNum) {
            double zhb = 0;
            if (currentNum <= 40) {
                zhb = 0;
            } else if (currentNum <= 100 && currentNum > 40) {
                double i = currentNum - 40;
                String txdouble = txdouble(i, 60.0);
                zhb = Double.parseDouble(txdouble)*0.5;
            } else if (currentNum <= 160 && currentNum > 100) {
                double i = currentNum - 100;
                String txdouble = txdouble(i, 60.0);
                String txdouble2 = txdouble(1, 3);
                zhb = Double.parseDouble(txdouble) * Double.parseDouble(txdouble2) + 0.5;
            } else if (currentNum <= 200 && currentNum > 160) {
                double i = currentNum - 160;
                String txdouble = txdouble(i, 40.0);
                String txdouble2 = txdouble(1, 6);
                String txdouble3 = txdouble(1, 3);
                zhb = Double.parseDouble(txdouble) * Double.parseDouble(txdouble2) + Double.parseDouble(txdouble3) + 0.5;
            }
            sweep = (int)(zhb * 270);
        } else {
            sweep = sweepAngle;
        }

画刻度

Paint paint = new Paint();
        paint.setColor(getResources().getColor(R.color.color666));
        paint.setAntiAlias(true);
        paint.setTextSize(textSize);
        canvas.drawText("40", CenterX - mEdge - mStrokeWidthBig - textSize * 2-dp2px(16),CenterY + mEdge + 20, paint);
        canvas.drawText("60", CenterX - mRadius - mStrokeWidthBig - textSize* 2-dp2px(13), CenterY + 10, paint);
        canvas.drawText("100", CenterX - textSize, CenterY - mRadius- mStrokeWidthBig - textSize-dp2px(10), paint);
        canvas.drawText("160", CenterX + mRadius + mStrokeWidthBig + textSize+dp2px(7),CenterY + 10, paint);
        canvas.drawText("200", CenterX + mEdge + mStrokeWidthBig + textSize+dp2px(9),CenterY + mEdge + 30, paint);

布局文件很简单

<com.jorli.test0.view.RoundIndicatorView
            android:id="@+id/my_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
