Example 16 with RectF

use of android.graphics.RectF in project CircleBar by songnick.

the class AccelerationProgress method drawAccBall.

private void drawAccBall(Canvas canvas) {

    float y = (float) Math.sin(sweepAngle) * (getBigCircleRadius());
    float x = (float) Math.cos(sweepAngle) * (getBigCircleRadius());
    int restoreCount = canvas.save();
    //change aix center position
    canvas.translate(rectF.centerX(), rectF.centerY());
