Requirements: Based on the data, the Android side generates a word and saves it locally.
After checking some information, it seems that Android does not have a formal word operation library, which is basically implemented with Java API and Apache POI, but this version is more compatible with Android. , There are a lot of pitfalls...
Here, you need word to operate radar charts, line charts, histograms, etc., you need POI4. ...), there is no way to use the 3.x version, let's talk about the chart...
1.gradle depends on POI
app directory build.gradle, add complete dependencies:
dependencies {
...
implementation group: 'org.apache.poi', name: 'poi-ooxml', version: '3.17'
implementation group: 'org.apache.xmlbeans', name: 'xmlbeans', version: '3.1.0'
implementation 'javax.xml.stream:stax-api:1.0'
implementation 'com.fasterxml:aalto-xml:1.2.2'
...
}
2. Add a new paragraph
/**
* 添加段落内容
*
* @param document word文档对象 XWPFDocument document = new XWPFDocument()
* @param fontSize 字体大小
* @param fontFamily 字体类型
* @param text 标题
*/
public static void addParagraph(XWPFDocument document, int fontSize, String fontFamily, String text) {
//创建空白word文档
//XWPFDocument document = new XWPFDocument()
XWPFParagraph paragraph = document.createParagraph();
//内容左对齐
paragraph.setAlignment(ParagraphAlignment.valueOf(STJc.INT_LEFT));
XWPFRun run = paragraph.createRun();
run.setFontSize(13);
run.setFontFamily("黑体");
run.addTab();
run.setText(text);
run.addBreak();
}
3. Add a new form
- document.createTable(1, 2);
Create a table with 1 row and 2 columns
table.getRow(0).getCell(0).setText()
table.getRow(0).getCell(1).setText() - document.createTable();
Create 1 row and 1 column by default
table.getRow(0).getCell(0).setText()
table.getRow(0).addNewTableCell().setText()
/**
* 添加表格
* XWPFDocument document = new XWPFDocument()
*
* @param document word文档对象.
*/
public static void addTable(XWPFDocument document) {
//创建表格 1行 list.size 列
//XWPFTable table = document.createTable(1, 2);
XWPFTable table = document.createTable();
CTTbl tTbl = table.getCTTbl();
CTTblPr tTblPr = tTbl.getTblPr() == null ? tTbl.addNewTblPr() : tTbl.getTblPr();
CTTblWidth tblWidth = tTblPr.isSetTblW() ? tTblPr.getTblW() : tTblPr.addNewTblW();
//设置表格宽度
tblWidth.setType(STTblWidth.DXA);
tblWidth.setW(new BigInteger("8000"));
table.getRow(0).setHeight(1000);
//第一列
setCellStr(table.getRow(0).getCell(0), "主题一", 3000);
//setCellStr(table.getRow(0).getCell(1), "孤勇者-陈奕迅", 5000);
//第二列
setCellStr(table.getRow(0).addNewTableCell(), "孤勇者-陈奕迅", 5000);
XWPFTableRow row_1 = table.createRow();
row_1.setHeight(1000);
setCellStr(row_1.getCell(0), "主题二", 3000);
setCellStr(row_1.getCell(1), "再回首-岩贵|再回首恍然如梦", 5000);
XWPFTableRow row_2 = table.createRow();
row_2.setHeight(1000);
setCellStr(row_2.getCell(0), "主题三", 3000);
setCellStr(row_2.getCell(1), "光辉岁月-黄家驹", 5000);
}
Set the cell properties
and pay attention to horizontal centering: this is a bit of a pit, and it is much worse. It is all ctTc.getPList().get(0).addNewPPr().addNewJc().setVal(STJc.CENTER);, because the version problem needs to be changed into ctTc.getPArray()[0].addNewPPr().addNewJc().setVal(STJc.CENTER);, the compilation does not report an error, and the method cannot be found once it is run. You click on the key code and there is this method...
private static void setCellStr(XWPFTableCell cell, String str, int w) {
CTTc ctTc = cell.getCTTc();
CTTcPr ctTcPr = ctTc.addNewTcPr();
ctTcPr.addNewTcW().setW(BigInteger.valueOf(w));
//上下居中
cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER);
//水平居中
//ctTc.getPList().get(0).addNewPPr().addNewJc().setVal(STJc.CENTER);
ctTc.getPArray()[0].addNewPPr().addNewJc().setVal(STJc.CENTER);
cell.setText(str);
}
4. Generate a new word according to the template
I put the template in the assets directory, and then judge whether the field contains $. Then replace it with what we need.
4.1 Replacing paragraphs
/**
* 替换段落文本
*
* @param document docx解析对象
* @param textMap 需要替换的信息集合
*/
public static void changeText(XWPFDocument document, Map<String, String> textMap) {
//获取段落集合
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs) {
//判断此段落时候需要进行替换
String text = paragraph.getText();
Log.i(TAG, "changeText:行 " + text);
if (text.contains("$")) {
List<XWPFRun> runs = paragraph.getRuns();
for (XWPFRun run : runs) {
//替换模板原来位置
Log.i(TAG, "changeText:行内 " + run.getText(run.getTextPosition()));
run.setText(changeValue(run.toString(), textMap), 0);
}
}
}
}
4.2 Substitution Form
/**
* 替换表格对象方法
*
* @param document docx解析对象
* @param textMap 需要替换的信息集合
*/
public static void changeTable(XWPFDocument document, Map<String, String> textMap) {
//获取表格对象集合
List<XWPFTable> tables = document.getTables();
for (int i = 0; i < tables.size(); i++) {
Log.i(TAG, "changeTable: 1" + tables.get(i).getText());
//只处理行数大于等于2的表格，且不循环表头
XWPFTable table = tables.get(i);
if (table.getRows().size() > 1) {
//判断表格是需要替换还是需要插入，判断逻辑有$为替换，表格无$为插入
if (table.getText().contains("$")) {
List<XWPFTableRow> rows = table.getRows();
//遍历表格,并替换模板
eachTable(rows, textMap);
}
}
}
}
5. Complete tool code
public class PoiWordUtils {

//行间距
//paragraph.setSpacingBefore(1);
XWPFRun run = paragraph.createRun();
run.setFontSize(fontSize);
