本文实例为大家分享了Android实现电影院选座效果展示的具体代码，供大家参考，具体内容如下

这是一个简单的电影院选座效果，实现该效果大致分为三步：

1.自定义view进行绘制；

2.手势缩放效果的实现；

3.手势触摸被选和未被选效果的实现；

先来看第一步，效果的绘制；

public class MoveSeatView extends View {

private final boolean DBG = false;

private Paint paint = new Paint();

private Matrix matrix = new Matrix();

private Matrix tempMatrix = new Matrix();

//座位水平间距

private int spacing;

//座位垂直间距

private int verSpacing;

//行号宽度

private int numberWidth;

//行数

private int row;

//列数

private int column;

//可选座位的图片

private Bitmap seatBitmap;

//选中时座位的图片

private Bitmap checkedSeatBitmap;

private int lastX;

private int lastY;

//整个座位图的宽度

private int seatBitmapWidth;

private int seatBitmapHeight;

private float screenHeight;

//屏幕的最小宽度

private int defaultScreenWidth;

//标识是否正在缩放

private boolean isScaling;

private float scaleX, scaleY;

//是否是第一次缩放

private boolean firstScale = true;

private boolean isOnClick;

private int downX, downY;

private boolean pointer;

//用于存储已经选在好的座位

public ArrayList list;

/**

* 默认的座位图片的宽度，如果使用的自己的座位的图片比这个尺寸大或者小，会缩放到这个大小

*/

private float defaultImgW = 40;

private float defaultImgH = 34;

/**

* 座位图片的宽度

*/

private int seatWidth = 40;

/**

* 座位图片的高度

*/

private int seatHeight = 34;

private float zoom;

float xScalel = 1;

float yScalel = 1;

public MoveSeatView(Context context) {

this(context, null);

}

public MoveSeatView(Context context, AttributeSet attrs) {

this(context, attrs, 0);

}

public MoveSeatView(Context context, AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

}

private void init() {

spacing = (int) dip2px(5);

verSpacing = (int) dip2px(10);

defaultScreenWidth = (int) dip2px(80);

seatBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.seat_default);

xScalel = defaultImgW / seatBitmap.getWidth();

yScalel = defaultImgH / seatBitmap.getHeight();

checkedSeatBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.seat_green);

seatBitmapWidth = (int) (column * seatBitmap.getWidth() * xScalel + (column - 1) * spacing);

seatBitmapHeight = (int) (row * seatBitmap.getHeight() * yScalel + (row - 1) * verSpacing);

paint.setColor(Color.RED);

numberWidth = (int) dip2px(20);

screenHeight = dip2px(20);

list = new ArrayList<>();

matrix.postTranslate(numberWidth + spacing, screenHeight + 1 + verSpacing);

}

}
