排列布局有问题，楼主联系方式能给一个吗

就第一二个是正方形，其他的都变成长方形了

删除图片时回调传值错误

需要改动的

DraggableItemView.java

    @Override
    public void onDeleteClick(View view) {
        // parentView.onDeleteImage(imagePath, DraggableItemView.this);
        imagePath = null;
        imageView.setImageBitmap(null);
        addView.setVisibility(View.VISIBLE);
        parentView.onDeleteImage(DraggableItemView.this);
    }

imagePath = null 导致回调给DraggableSquareView在通过 deleteView.getImagePath() 获取到的已删除图片路径为空。应该将path传递给 parentView.onDeleteImag(imagePath, DraggableItemView.this) 再执行imagePath = null

需要改动的

DraggableSquareView.java

    /**
     * 删除某一个ImageView时，该imageView变成空的，需要移动到队尾
     */
    public void onDeleteImage(DraggableItemView deleteView) {
        if ((int)deleteView.getTag() == 0){
            return;
        }
        int status = deleteView.getStatus();
        int lastDraggableViewStatus = -1;
        // 需要将该回调提前到该位置，否则传递的status也就是删除的view的index索引是移动后的索引
        if (imageChangesListener != null) {
            imageChangesListener.onImageDeleted(deleteView.getImagePath(), status);
        }
        // 顺次将可拖拽的view往前移
        for (int i = status + 1; i < allStatus.length; i++) {
            DraggableItemView itemView = getItemViewByStatus(i);
            if (itemView.isDraggable()) {
                // 可拖拽的view往前移
                lastDraggableViewStatus = i;
                switchPosition(i, i - 1);
            } else {
                break;
            }
        }
        if (lastDraggableViewStatus > 0) {
            // 被delete的view移动到队尾
            deleteView.switchPosition(lastDraggableViewStatus);
        }
    }
