本項目主要介紹：
本項目主要自定義AnimCheckBox 集成View，提供選擇的監聽接口OnCheckedChangeListener
主要由drawCircle（）方法和drawHook(Canvas canvas)；
private void drawCircle(Canvas canvas){
        initDrawStrokeCirclePaint();
        canvas.drawArc(mRectF, 202, mSweepAngle, false, mPaint);
        initDrawAlphaStrokeCirclePaint();
        canvas.drawArc(mRectF, 202, mSweepAngle - 360, false, mPaint);
        initDrawInnerCirclePaint();
        canvas.drawArc(mInnerRectF, 0, 360, false, mPaint);
    }html

    private void drawHook(Canvas canvas){
        if (mHookOffset == 0)
            return;
        initDrawHookPaint();
        mPath.reset();
        float offset;
        if (mHookOffset <= (2 * size/3 - mHookStartY - mBaseLeftHookOffset)){
            mPath.moveTo(mBaseLeftHookOffset, mBaseLeftHookOffset + mHookStartY);
            mPath.lineTo(mBaseLeftHookOffset + mHookOffset, mBaseLeftHookOffset + mHookStartY + mHookOffset);
        }else if (mHookOffset <= mHookSize){
            mPath.moveTo(mBaseLeftHookOffset, mBaseLeftHookOffset + mHookStartY);
            mPath.lineTo(2 * size / 3 - mHookStartY, 2 * size / 3);
            mPath.lineTo(mHookOffset + mBaseLeftHookOffset,
                    2 * size/3 - (mHookOffset - (2 * size/3 - mHookStartY - mBaseLeftHookOffset)));
        }else {
            offset = mHookOffset - mHookSize;
            mPath.moveTo(mBaseLeftHookOffset + offset, mBaseLeftHookOffset + mHookStartY + offset);
            mPath.lineTo(2 * size / 3 - mHookStartY, 2 * size / 3);
            mPath.lineTo(mHookSize + mBaseLeftHookOffset + offset,
                    2 * size/3 - (mHookSize - (2 * size/3 - mHookStartY - mBaseLeftHookOffset) + offset));
        }
        canvas.drawPath(mPath, mPaint);
