我正在使用OneDrive sdk从OneDrive下载.docx文件。它下载成功，但我需要将其转换为.txt格式，但我做不到。
有没有人知道如何在 android 中转换或从.docx文件中获取文本？
我可以得到.docx文件的InputStream。
这是从OneDrive下载文件的代码
InputStream inputStream = iOneDriveClient.getDrive().getItems(fileID).getContent().buildRequest().get();
OutputStream out = new FileOutputStream(mPath);
int read;
byte[] bytes = new byte[1024];
while ((read = inputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
inputStream.close();
此代码已在doInBackground
编辑
我添加了Apache POI库，但我无法编译它
我在很多文件上遇到冲突

冲突错误是
在模块 docx4j-6.1.1-SNAPSHOT-shaded.jar (docx4j-6.1.1-SNAPSHOT-shaded.jar( 和 jackson-core-2.9.6.jar (com.fasterxml.jackson.core：jackson-core：jackson-core：2.9.6( 中找到的重复类 com.fasterxml.jackson.core：Base64Variant
您可以使用 Apache POI
从文档：
对于Word 97 - Word 2003中的.doc文件，在暂存器中有org.apache.poi.hwpf.extractor.WordExtractor，它将返回文档的文本。
下面是文档中的示例：
FileInputStream fis = new FileInputStream(inputFile);
POIFSFileSystem fileSystem = new POIFSFileSystem(fis);
// Firstly, get an extractor for the Workbook
POIOLE2TextExtractor oleTextExtractor =
ExtractorFactory.createExtractor(fileSystem);
// Then a List of extractors for any embedded Excel, Word, PowerPoint
// or Visio objects embedded into it.
POITextExtractor[] embeddedExtractors =
ExtractorFactory.getEmbededDocsTextExtractors(oleTextExtractor);
for (POITextExtractor textExtractor : embeddedExtractors) {
// If the embedded object was an Excel spreadsheet.
if (textExtractor instanceof ExcelExtractor) {
ExcelExtractor excelExtractor = (ExcelExtractor) textExtractor;
System.out.println(excelExtractor.getText());
}
// A Word Document
else if (textExtractor instanceof WordExtractor) {
WordExtractor wordExtractor = (WordExtractor) textExtractor;
String[] paragraphText = wordExtractor.getParagraphText();
for (String paragraph : paragraphText) {
System.out.println(paragraph);
}
// Display the document's header and footer text
System.out.println("Footer text: " + wordExtractor.getFooterText());
System.out.println("Header text: " + wordExtractor.getHeaderText());
}
// PowerPoint Presentation.
else if (textExtractor instanceof PowerPointExtractor) {
PowerPointExtractor powerPointExtractor =
(PowerPointExtractor) textExtractor;
System.out.println("Text: " + powerPointExtractor.getText());
System.out.println("Notes: " + powerPointExtractor.getNotes());
}
}
在尝试使用 Apache POI 库从.docx中提取文本后，我浪费了整个周末。但无法相信猛犸象图书馆是多么容易。
将其添加到依赖项
implementation 'org.zwobble.mammoth:mammoth:1.4.2'
下面是结果活动中的代码
if (resultCode == Activity.RESULT_OK) {
val converter = DocumentConverter()
val uri = data?.data;
val result: Result<String>? = converter.extractRawText(contentResolver.openInputStream(uri!!))
val text_extracted = result!!.getValue()
Log.e("Docx etracted TeXT:", text_extracted)
select.text= text_extracted
}
希望它有帮助
