将Rect转换为RectF

Question

将Rect变量转换为RectF变量的最佳方法是什么？我无法施展它。

RectF rect = (RectF) currentRect; //produces an error

Answer 1

RectF rect = new RectF(currentRect);

Answer 2

“不应在onDraw中完成”

// As class fields,
Rect rect = new Rect();
RectF rectF = new RectF();

...
onDraw(Canvas canvas) {
    ...
    rectF.set(rect);
    ...
}
