方法，保证绘制的是圆 包正绘图是圆形的前提是： 保证 RectF 切割的是正方形， 那么保证 RextF 围成的是正方形，就要需要知道正方形四边距离控件边界的距离 也就是我们需要计算四个整型变量 ：1.mPaddingLeft...加一个默认的padding值，为了防止用camera旋转时钟时造成四周超出view大小 */ private float mDefaultPadding; private float mPaddingLeft...getPaddingTop() - getPaddingBottom()) / 2;// 各个指针长度 mDefaultPadding = 0.12f * mRadius; mPaddingLeft
