我目前无法使用动态壁纸进行一些非常密集的绘图。但是，在测试我的代码时，我发现壁纸是滞后的，并且在屏幕旋转时会被破坏。
在我的绘制方法中，我有这个：
mRectArray = new Rect[] {
new Rect(0, 0, c.getWidth(),
(c.getHeight() + statusBarHeight) / 20),
new Rect(0, (c.getHeight() + statusBarHeight) / 20,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 2),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 2,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 3),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 3,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 4),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 4,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 5),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 5,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 6),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 6,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 7),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 7,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 8),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 8,

(c.getHeight() + statusBarHeight) / 20 * 9),

这是40个矩形，不断在onDraw上初始化。 现在，问题是这些矩形必须不断初始化，因为我正在为20个矩形的右侧设置动画......
我还有另外40个if语句用于动画矩形..
如何压缩我的代码以免牺牲性能？

使用onSurfaceChange（）函数的高度和宽度在onSurfaceChange（）中初始化数组。
