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);
public Bitmap getBitmapFuselage(float rectFCabinWidth) {
Canvas canvas = null;
int w = getMeasuredWidth();
int h = getMeasuredHeight();
if (mBitmapFuselage == null) {
mBitmapFuselage = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);
canvas = new Canvas(mBitmapFuselage);
pathFuselage.moveTo(w / 2f - rectFCabinWidth / 2f - dip2px(2),
rectFCabin.top + rectFCabinWidth / 2f);
pathFuselage.cubicTo(
w / 2f - rectFCabinWidth / 4f,
rectFCabin.top - rectFCabinWidth * 1.2f,
w / 2f + rectFCabinWidth / 4f,
rectFCabin.top - rectFCabinWidth * 1.2f,
w / 2f + rectFCabinWidth / 2f + dip2px(2),
rectFCabin.top + rectFCabinWidth / 2f
);
rectFCabin.top = rectFCabin.top + dip2px(10);//机翼向下平移距离
pathFuselage.lineTo(w / 2f + rectFCabinWidth / 2f + dip2px(2)
, rectFCabin.top + rectFCabin.height() / 3f);
pathFuselage.lineTo(w
, rectFCabin.top + rectFCabin.height() * 0.55f);
pathFuselage.lineTo(w
, rectFCabin.top + rectFCabin.height() * 0.55f + rectFCabin.width() * 0.8f);
pathFuselage.lineTo(rectFCabin.right + rectFCabin.width() / 2 * 1.5f
, rectFCabin.top + rectFCabin.height() / 2f + rectFCabin.height() / 6f / 2f);
pathFuselage.lineTo(w / 2f + rectFCabinWidth / 2f + dip2px(2)
, rectFCabin.top + rectFCabin.height() / 2f + rectFCabin.height() / 6f / 2f);
//
pathFuselage.lineTo(w / 2f + rectFCabinWidth / 2f + dip2px(2)
, rectFCabin.bottom - rectFCabinWidth / 2f);
pathFuselage.cubicTo(
w / 2f + rectFCabinWidth / 4f,
rectFCabin.bottom + rectFCabinWidth * 2.5f,
w / 2f - rectFCabinWidth / 4f,

pathFuselage.lineTo(w / 2f - rectFCabinWidth / 2f - dip2px(2)
, rectFCabin.top + rectFCabin.height() / 2f + rectFCabin.height() / 6f / 2f);
pathFuselage.lineTo(rectFCabin.left - rectFCabin.width() / 2 * 1.5f
, rectFCabin.top + rectFCabin.height() / 2f + rectFCabin.height() / 6f / 2f);
pathFuselage.lineTo(0
, rectFCabin.top + rectFCabin.height() * 0.55f + rectFCabin.width() * 0.8f);
pathFuselage.lineTo(0
, rectFCabin.top + rectFCabin.height() * 0.55f);
pathFuselage.lineTo(w / 2f - rectFCabinWidth / 2f - dip2px(2)
, rectFCabin.top + rectFCabin.height() / 3f);
pathFuselage.close();
mPaint.setColor(Color.WHITE);
mPaint.setAlpha(150);

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^^
