Mobile Services批量提交数据，參考了文章：Inserting
multiple items at once in Azure Mobile Services。里面事实上已经介绍得比較清楚了。但因为是英文。并且有些地方交待得不清楚。也没有Android的演示样例。故下文以Android版本号的开发为例作个补充。

首先在Mobile Services项目里新建AllToDoItems以及ToDoItem表。点击AllToDoItems，再点击script标签。将里面的内容替换例如以下：

function insert(item, user, request) {

    var table = tables.getTable('ToDoItem');

    populateTable(table, request, item.todos);

}

function populateTable(table, request, films) {

    var index = 0;

    films.forEach(changeReleaseDate);

    var insertNext = function () {

        if (index >= films.length) {

            request.respond(201, { id: 1, status: 'Table populated successfully' });

        } else {

            var toInsert = films[index];

            table.insert(toInsert, {

                success: function () {

                    index++;

                    if ((index % 20) === 0) {

                        console.log('Inserted %d items', index);

                    }

                    insertNext();

                }

            });

        }

    };

    insertNext();

}

function changeReleaseDate(obj) {

    var releaseDate = obj.ReleaseDate;

    if (typeof releaseDate === 'string') {

        releaseDate = new Date(releaseDate);

        obj.ReleaseDate = releaseDate;

    }

}

服务端的工作到此完毕。

client新建两个类。分别例如以下：

package com.example.ecodriveiot;

/**

 * Represents an item in a ToDo list

 */

public class ToDoItem {

	/**

	 * Item text

	 */

	@com.google.gson.annotations.SerializedName("text")

	private String mText;

	/**

	 * Item Id

	 */

	@com.google.gson.annotations.SerializedName("id")

	private String mId;

	/**

	 * Indicates if the item is completed

	 */

	@com.google.gson.annotations.SerializedName("complete")

	private boolean mComplete;

	/**

	 * ToDoItem constructor

	 */

	public ToDoItem() {

	}

	@Override

	public String toString() {

		return getText();

	}

	/**

	 * Initializes a new ToDoItem

	 *

	 * @param text

	 *            The item text

	 * @param id

	 *            The item id

	 */

	public ToDoItem(String text, String id) {

		this.setText(text);

		this.setId(id);

	}

	/**

	 * Returns the item text

	 */

	public String getText() {

		return mText;

	}

	/**

	 * Sets the item text

	 *

	 * @param text

	 *            text to set

	 */

	public final void setText(String text) {

		mText = text;

	}

	/**

	 * Returns the item id

	 */

	public String getId() {

		return mId;

	}

	/**

	 * Sets the item id

	 *

	 * @param id

	 *            id to set

	 */

	public final void setId(String id) {

		mId = id;

	}

	/**

	 * Indicates if the item is marked as completed

	 */

	public boolean isComplete() {

		return mComplete;

	}

	/**

	 * Marks the item as completed or incompleted

	 */

	public void setComplete(boolean complete) {

		mComplete = complete;

	}

	@Override

	public boolean equals(Object o) {

		return o instanceof ToDoItem && ((ToDoItem) o).mId == mId;

	}

}

package com.example.ecodriveiot;

public class AllToDoItems {

	@com.google.gson.annotations.SerializedName("id")

	public String id;

	public String status;

	public ToDoItem[] todos;

}

批量提交的代码例如以下：

ToDoItem item = new ToDoItem();

		item.setText("test");

		item.setComplete(false);

		ToDoItem[] items = new ToDoItem[2];

		items[0]=item;

		items[1]=item;

		// Insert the new item

		/*mToDoTable.insert(item, new TableOperationCallback<ToDoItem>() {

			public void onCompleted(ToDoItem entity, Exception exception, ServiceFilterResponse response) {

				if (exception == null) {

					if (!entity.isComplete()) {

						mAdapter.add(entity);

					}

				} else {

					createAndShowDialog(exception, "Error");

				}

			}

		});*/

		AllToDoItems allToDoItems = new AllToDoItems();

		allToDoItems.todos=items;

		mClient.getTable(AllToDoItems.class).insert(allToDoItems, new TableOperationCallback<AllToDoItems>() {

			public void onCompleted(AllToDoItems entity, Exception exception, ServiceFilterResponse response) {

				if (exception == null) {

					Log.i("Debug", "status:"+entity.status);

				} else {

					createAndShowDialog(exception, "Error");

				}

			}

		});

上面的代码事实上是在sdk demo的基础上改的，mClient的初始化自己加上就可以。其它client的开发事实上是类似的，能够查看英文原文。当然，里面的ToDoItem[] todos可以改变的ArrayList<ToDoItem> todos。
