在这个基础上加入了缩略图

定义枚举把座位分为已选，要选，未选。
座位分左中右
舱位分头等，二等，经济，末尾。
enum SeatState {
Normal, Selected, Selecting
}
enum SeatType {
Left, Middle, Right
}
enum CabinType {
Frist, Second, Tourist, Last
}
定义HashMap来存放位置信息
HashMap<String, RectF> mSeats= new HashMap<>();
HashMap的key是位置的序号，比如4排5坐 「4#5」未做唯一标识。
value的类型是RectF来判断点是否在改区域中，来控制选中和未选中的区分。
RectF.contains(x, y)
利用Matrix对机舱和机翼放缩和平移
机舱和机翼都是利用贝赛尔曲线画的，这个就不具体贴代码了
matrix.postScale(sx,sy);
matrix.postTranslate(dx,dy);
canvas.drawBitmap(getBitmapFuselage(rectFCabinWidth), matrix, mPaint);

int w = getMeasuredWidth();

canvas = new Canvas(mBitmapFuselage);
pathFuselage.moveTo(w / 2f - rectFCabinWidth / 2f - dip2px(2),
rectFCabin.top + rectFCabinWidth / 2f);
pathFuselage.cubicTo(

rectFCabin.top = rectFCabin.top + dip2px(10);//机翼向下平移距离

Usage
mFlightSeatView.startAnim(true);// false zoom in,true zoom out
mFlightSeatView.setEmptySelecting();//clear
mFlightSeatView.setSeatSelected(row, column);
如果觉得还不错，就给我打赏颗星星吧^^
