在Android中通过SD卡编程打印MS-Office文档,可以按照以下步骤进行:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Environment.getExternalStorageDirectory()
方法获取SD卡的根目录路径,然后拼接上文档的相对路径。String sdCardPath = Environment.getExternalStorageDirectory().getAbsolutePath();
String filePath = sdCardPath + "/path/to/your/document.docx";
File file = new File(filePath);
FileInputStream fis = new FileInputStream(file);
XWPFDocument document = new XWPFDocument(fis);
// 读取文档内容
String content = "";
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs) {
content += paragraph.getText();
}
fis.close();
PrintManager printManager = (PrintManager) getSystemService(Context.PRINT_SERVICE);
String jobName = "Printing Document";
PrintDocumentAdapter printAdapter = new PrintDocumentAdapter() {
@Override
public void onWrite(PageRange[] pages, ParcelFileDescriptor destination, CancellationSignal cancellationSignal, WriteResultCallback callback) {
try {
OutputStream output = new FileOutputStream(destination.getFileDescriptor());
output.write(content.getBytes());
callback.onWriteFinished(new PageRange[]{PageRange.ALL_PAGES});
} catch (IOException e) {
// 处理写入错误
}
}
@Override
public void onLayout(PrintAttributes oldAttributes, PrintAttributes newAttributes, CancellationSignal cancellationSignal, LayoutResultCallback callback, Bundle extras) {
if (cancellationSignal.isCanceled()) {
callback.onLayoutCancelled();
return;
}
PrintDocumentInfo.Builder builder = new PrintDocumentInfo.Builder(jobName);
builder.setContentType(PrintDocumentInfo.CONTENT_TYPE_DOCUMENT)
.setPageCount(PrintDocumentInfo.PAGE_COUNT_UNKNOWN)
.build();
callback.onLayoutFinished(builder.build(), !newAttributes.equals(oldAttributes));
}
};
printManager.print(jobName, printAdapter, null);
请注意,以上代码仅为示例,具体实现可能需要根据你的需求进行调整。
