1 | # Android_Excel
2 | 在android中生成excel
3 | ##效果图
4 | 
5 | ##初始化数据
6 | 首先我们要先造下测试数据，这里我把数据写死在一个常量类Const中，如下：
7 |
8 | ```
9 | public class Const {
10 | public interface OrderInfo{
11 | public static final String[][] orderOne = new String[][] {{ "123", "九龙", "13294352311",
12 | "武汉市关山口" },{ "124", "咱家", "13294352312",
13 | "武汉市水果湖" },{ "125", "陈家", "13294352315",
14 | "武汉市华师" },{ "126", "李", "13294352316",
15 | "武汉市杨家湾" }};
16 | }
17 | }
18 | ```
19 | 理论上这些数据是从后台读过来的。
20 | 本文模拟打印订单的信息，所以这里还需要一个订单Model类：
21 |
22 | ```
23 | public class Order implements Serializable {
24 |
25 | public String id;
26 |
27 | public String restPhone;
28 |
29 | public String restName;
30 |
31 | public String receiverAddr;
32 |
33 |
34 | public Order(String id,String restPhone, String restName, String receiverAddr) {
35 | this.id = id;
36 | this.restPhone = restPhone;
37 | this.restName = restName;
38 |
39 | this.receiverAddr = receiverAddr;
40 | }
41 | }
42 | ```
43 |
44 | ##存内存卡
45 | 接下来我们要判断一下内存卡是否存在，内存是否足够大。先获取指定目录下内存的大小：
46 |
47 | ```
48 | /** 获取SD可用容量 */
49 | private static long getAvailableStorage(Context context) {
50 | String root = context.getExternalFilesDir(null).getPath();
51 | StatFs statFs = new StatFs(root);
52 | long blockSize = statFs.getBlockSize();
53 | long availableBlocks = statFs.getAvailableBlocks();
54 | long availableSize = blockSize * availableBlocks;
55 | // Formatter.formatFileSize(context, availableSize);
56 | return availableSize;
57 | }
58 | ```
59 | 这里用到的路径是getExternalFilesDir，它指定的是SDCard/Android/data/你的应用的包名/files/ 目录这个目录，它用来放一些长时间保存的数据，当应用被卸载时，会同时会删除。类似这种情况的还有getExternalCacheDir方法，只是它一般用来存放临时文件。之后通过StatFs来计算出可用容量的大小。
60 | 接下来在写入excel前对内存进行判断，如下：
61 |
62 | ```
63 | if(!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)&&getAvailableStorage()>1000000) {
64 | Toast.makeText(context, "SD卡不可用", Toast.LENGTH_LONG).show();
65 | return;
66 | }
67 | File file;
68 | File dir = new File(context.getExternalFilesDir(null).getPath());
69 | file = new File(dir, fileName + ".xls");
70 | if (!dir.exists()) {
71 | dir.mkdirs();
72 | }
73 | ```
74 | 如果内存卡不存在或内存小于1M，不进行写入，然后创建相应的文件夹并起名字。接下来重点看下如何写入excel。
75 | ##生成写入excel
76 |
77 | - 导入相关包
78 | 这里需要导入jxl包，它主要就是用于处理excel的，这个包我会附在项目放在github中，后面会给出链接。
79 | - 生成excel工作表
80 | 以下代码是在指定路径下生成excel表，此时只是一个空表。
81 |
82 |
83 | ```
84 | WritableWorkbook wwb;
85 | OutputStream os = new FileOutputStream(file);
86 | wwb = Workbook.createWorkbook(os);
87 | ```
88 |
89 | - 添加sheet表
90 | 熟悉excel操作的都知道excel可以新建很多个sheet表。以下代码生成第一个工作表，名字为“订单”：
91 |
92 |
93 | ```
94 | WritableSheet sheet = wwb.createSheet("订单", 0);
95 | ```
96 |
97 | - 添加excel表头
98 | 添加excel的表头，这里可以自定义表头的样式，先看代码：
99 |
100 |
101 | ```
102 | String[] title = { "订单", "店名", "电话", "地址" };
103 | Label label;
104 | for (int i = 0; i < title.length; i++) {
105 | // Label(x,y,z) 代表单元格的第x+1列，第y+1行, 内容z
106 | // 在Label对象的子对象中指明单元格的位置和内容
107 | label = new Label(i, 0, title[i], getHeader());
108 | // 将定义好的单元格添加到工作表中
109 | sheet.addCell(label);
110 | }
111 | ```
112 | 这里表头信息我写死了。表的一个单元格对应一个Label，如label(0,0,"a")代表第一行第一列所在的单元格信息为a。getHeader()是自定义的样式，它返回一个 WritableCellFormat 。来看看如何自定义样式：
113 |
114 |
115 | ```
116 | public static WritableCellFormat getHeader() {
117 | WritableFont font = new WritableFont(WritableFont.TIMES, 10,
118 | WritableFont.BOLD);// 定义字体
119 | try {
120 | font.setColour(Colour.BLUE);// 蓝色字体
121 | } catch (WriteException e1) {
122 | e1.printStackTrace();
123 | }
124 | WritableCellFormat format = new WritableCellFormat(font);
125 | try {
126 | format.setAlignment(jxl.format.Alignment.CENTRE);// 左右居中
127 | format.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);// 上下居中
128 | format.setBorder(Border.ALL, BorderLineStyle.THIN,
129 | Colour.BLACK);// 黑色边框
130 | format.setBackground(Colour.YELLOW);// 黄色背景
131 | } catch (WriteException e) {
132 | e.printStackTrace();
133 | }
134 | return format;
135 | }
136 | ```
137 | 看上面代码就很清楚了，通过获得WritableFont 来自定义字体的一些样式，如颜色大小等，通过WritableCellFormat 来设置文本框的样式，可以设置边框底色等。具体的可以查api文档，这里只给出例子。
138 |
139 | - 添加excel内容。
140 |
141 |
142 | ```
143 | for (int i = 0; i < exportOrder.size(); i++) {
144 | Order order = exportOrder.get(i);
145 |
146 | Label orderNum = new Label(0, i + 1, order.id);
147 | Label restaurant = new Label(1, i + 1, order.restName);
148 | Label nameLabel = new Label(2,i+1,order.restPhone);
149 | Label address = new Label(3, i + 1, order.receiverAddr);
150 |
151 | sheet.addCell(orderNum);
152 | sheet.addCell(restaurant);
153 | sheet.addCell(nameLabel);
154 | sheet.addCell(address);
155 | Toast.makeText(context, "写入成功", Toast.LENGTH_LONG).show();
156 |
157 | }
158 | ```

86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.

93 |
94 | (a) You must give any other recipients of the Work or

97 | (b) You must cause any modified files to carry prominent notices
98 | stating that You changed the files; and
99 |
100 | (c) You must retain, in the Source form of any Derivative Works

103 | excluding those notices that do not pertain to any part of
104 | the Derivative Works; and
105 |
106 | (d) If the Work includes a "NOTICE" text file as part of its
107 | distribution, then any Derivative Works that You distribute must
108 | include a readable copy of the attribution notices contained

111 | of the following places: within a NOTICE text file distributed
112 | as part of the Derivative Works; within the Source form or
113 | documentation, if provided along with the Derivative Works; or,
114 | within a display generated by the Derivative Works, if and
115 | wherever such third-party notices normally appear. The contents
116 | of the NOTICE file are for informational purposes only and
117 | do not modify the License. You may add Your own attribution
118 | notices within Derivative Works that You distribute, alongside
119 | or as an addendum to the NOTICE text from the Work, provided
120 | that such additional attribution notices cannot be construed
121 | as modifying the License.
122 |
123 | You may add Your own copyright statement to Your modifications and
124 | may provide additional or different license terms and conditions
125 | for use, reproduction, or distribution of Your modifications, or
126 | for any such Derivative Works as a whole, provided Your use,
127 | reproduction, and distribution of the Work otherwise complies with
128 | the conditions stated in this License.
129 |
130 | 5. Submission of Contributions. Unless You explicitly state otherwise,
131 | any Contribution intentionally submitted for inclusion in the Work
132 | by You to the Licensor shall be under the terms and conditions of
133 | this License, without any additional terms or conditions.
134 | Notwithstanding the above, nothing herein shall supersede or modify
135 | the terms of any separate license agreement you may have executed
136 | with Licensor regarding such Contributions.
137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,
140 | except as required for reasonable and customary use in describing the
141 | origin of the Work and reproducing the content of the NOTICE file.
142 |
143 | 7. Disclaimer of Warranty. Unless required by applicable law or
144 | agreed to in writing, Licensor provides the Work (and each
145 | Contributor provides its Contributions) on an "AS IS" BASIS,
146 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 | implied, including, without limitation, any warranties or conditions
148 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 | PARTICULAR PURPOSE. You are solely responsible for determining the
150 | appropriateness of using or redistributing the Work and assume any
151 | risks associated with Your exercise of permissions under this License.
152 |
153 | 8. Limitation of Liability. In no event and under no legal theory,
154 | whether in tort (including negligence), contract, or otherwise,
155 | unless required by applicable law (such as deliberate and grossly
156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.
