PropertyAnimation

自定义柱状图，并实现了3种属性动画（横向，纵向，横纵混合）

横向,主要实现代码

  for (int i = 0; i < mBarCount; i++) {
        if (i < count * mBarProgress) {
            float maginTop = getMaginTop(mStepArray[i]);
            RectF recf = new RectF((mBarWidth + mBarMaginLeft) * i, mBarMaxHeight - maginTop + mBarMaginTop,
                    mBarWidth * (i + 1) + mBarMaginLeft * i, mBarMaxHeight + mBarMaginTop);
            canvas.drawRoundRect(recf, roundWidthX, roundWidthY, mBarPaint);
        }
    }		 

纵向,主要实现代码

for (int i = 0; i < mBarCount; i++) {
		if (i < count) {
			float maginTop = getMaginTop(mStepArray[i]);
			RectF recf = new RectF((mBarWidth + mBarMaginLeft) * i, mBarMaxHeight-(mBarMaxHeight-maginTop)*mBarProgress  + mBarMaginTop,
					mBarWidth * (i + 1) + mBarMaginLeft * i, mBarMaxHeight + mBarMaginTop);
			canvas.drawRoundRect(recf, roundWidthX, roundWidthY, mBarPaint);
		}
	}

横纵混合,主要实现代码

for (int i = 0; i < mBarCount*mBarProgress; i++) {
		if (i < count) {
			float maginTop = getMaginTop(mStepArray[i]);
			RectF recf = new RectF((mBarWidth + mBarMaginLeft) * i, mBarMaxHeight-(mBarMaxHeight-maginTop)*mBarProgress  + mBarMaginTop,
					mBarWidth * (i + 1) + mBarMaginLeft * i, mBarMaxHeight + mBarMaginTop);
			canvas.drawRoundRect(recf, roundWidthX, roundWidthY, mBarPaint);
		}
	}
