MyImg类

package packageName;import android.widget.ImageView;public class MyImg {    // 用于存储图片位置的索引    private int type;    private ImageView img;    public MyImg(int type) {        this.type = type;    }    public void setImg(ImageView img) {        this.img = img;    }    public ImageView getImg() {        return img;    }    // 获取图片索引    public int getType() {        return type;    }}
