无论我想要什么,我都可以使用以下代码生成它：

protected void onDraw(Canvas canvas) {

super.onDraw(canvas);

PointF mPoint1 = new PointF(w/1.2F, h/1.2F);

PointF mPoint2 = new PointF(w/24, h/1.2F);

Path myPath1 = new Path();

Paint paint = new Paint();

paint.setAntiAlias(true);

paint.setStyle(Style.STROKE);

paint.setStrokeWidth(2);

paint.setColor(Color.WHITE);

myPath1 = drawCurve(canvas, paint, mPoint1, mPoint2);

canvas.drawPath(myPath1, paint);

}

private Path drawCurve(Canvas canvas, Paint paint, PointF mPointa, PointF mPointb) {

Path myPath = new Path();

myPath.moveTo(63*w/64, h/10);

myPath.quadTo(mPointa.x, mPointa.y, mPointb.x, mPointb.y);

return myPath;

}

这将找到屏幕的两侧(横向模式),并将在屏幕上绘制完美的曲线.
