您可以使用 iText 创建 PDF。使用最新版本 (5.1.3) 并在构建路径中仅包含 itextpdf-5.1.3.jar。您可以使用类似的东西来完成 pdf 创建。
Document document = new Document();
file = Environment.getExternalStorageDirectory().getPath() + "/Hello.pdf"
PdfWriter.getInstance(document,new FileOutputStream(file));
document.open();
Paragraph p = new Paragraph("Hello PDF");
document.add(p);
document.close();
另外，不要忘记在 manifest.xml 中使用写入外部存储的权限。

It's Easy,For example

这是我使用 Itext 库创建包含文本和图像内容的 pdf 文件并将 pdf 文件存储在外部存储位置的示例编码。唯一的事情是您需要下载 itext 库并将其添加到您的项目中。
private void createPdf() {
// TODO Auto-generated method stub
com.itextpdf.text.Document document = new com.itextpdf.text.Document();
try {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/vindroid";
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();
Log.d("PDFCreator", "PDF Path: " + path);
File file = new File(dir, "sample.pdf");
FileOutputStream fOut = new FileOutputStream(file);
PdfWriter.getInstance(document, fOut);
//open the document
document.open();
Paragraph p1 = new Paragraph("Sample PDF CREATION USING IText");
Font paraFont= new Font(Font.FontFamily.COURIER);
p1.setAlignment(Paragraph.ALIGN_CENTER);
p1.setFont(paraFont);
//add paragraph to document
document.add(p1);
Paragraph p2 = new Paragraph("This is an example of a simple paragraph");
Font paraFont2= new Font(Font.FontFamily.COURIER,14.0f,0, CMYKColor.GREEN);
p2.setAlignment(Paragraph.ALIGN_CENTER);
p2.setFont(paraFont2);
document.add(p2);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getBaseContext().getResources(), R.drawable.ic_launcher);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
myImg.setAlignment(Image.MIDDLE);
//add image to document
document.add(myImg);
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
}
finally
{
document.close();
}
}

我创建了一个示例项目，用于使用itextpdf/itext7 库从数据创建 pdf 文件
示例项目链接：https ://github.com/rheyansh/RPdfGenerator
在您的应用程序 gradle 中添加以下依赖项：
implementation 'com.itextpdf:itext7-core:7.1.12'
重要笔记
在 AndroidManifest.xml 中添加 WRITE_EXTERNAL_STORAGE 权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
在 AndroidManifest.xml 中添加文件提供程序
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="com.rheyansh.rpdfgenerator.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
添加 XML 资源文件夹（参见示例文件夹中的 provider_paths.xml）
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="."/>
</paths>

R事务模型

var pricePerUnit: Double = 0.0
var quantity: Int = 0
var totalPrice: Double = 0.0
var transactionDateStr: String = ""
constructor() {

}
在您的活动类中编写以下函数以创建虚拟数据
private fun dummyModel(): RPdfGeneratorModel {
val list = dummyTransactions()
val header = "Statement"
val dummy = RPdfGeneratorModel(list, header)
return dummy
}
private fun dummyTransactions(): List<RTransaction> {
val list = arrayListOf<RTransaction>()
val i1 = RTransaction()
i1.custName = "Johan Store"
i1.itemName = "Snacks"
i1.quantity = 4
i1.pricePerUnit = 40.0
i1.totalPrice = i1.quantity * i1.pricePerUnit
i1.transactionDateStr = "10 Sep, 20"
i1.transType = RTransactionType.plus
list.add(i1)
val i2 = RTransaction()
i2.custName = "Alice Store"
i2.itemName = "Chocolate"
i2.quantity = 3
i2.pricePerUnit = 79.0
i2.totalPrice = i2.quantity * i2.pricePerUnit
i2.transactionDateStr = "9 Sep, 20"
i2.transType = RTransactionType.plus
list.add(i2)
val i3 = RTransaction()
i3.custName = "Alexa Mall"
i3.itemName = "Shoes"
i3.quantity = 2
i3.pricePerUnit = 177.0
i3.totalPrice = i3.quantity * i3.pricePerUnit
i3.transactionDateStr = "9 Sep, 20"
i3.transType = RTransactionType.minus
list.add(i3)
val i4 = RTransaction()
i4.custName = "Zainab Baba"
i4.itemName = "Chips"
i4.quantity = 5
i4.pricePerUnit = 140.0
i4.totalPrice = i4.quantity * i4.pricePerUnit
i4.transactionDateStr = "8 Sep, 20"
i4.transType = RTransactionType.plus
list.add(i4)
list.add(i1)
list.add(i2)
list.add(i3)
list.add(i4)
list.add(i1)
list.add(i2)
list.add(i3)
list.add(i4)
return list
}
现在调用 RPdfGenerator 函数。请务必在调用之前询问 WRITE_EXTERNAL_STORAGE 权限。有关更多详细信息，请查看示例项目
val dummyInfo = dummyModel()
RPdfGenerator.generatePdf(this, dummyInfo)

我在一个 java swing 应用程序中使用了 iText——它可以很好地创建一些基本的 PDF 文件。代码是这样的：
@Override public void buildPDF(List<Folder> folders) {
Document document = new Document();
String fname = "";
boolean open = false;
try {
// step 2:
// we create a writer that listens to the document
// and directs a PDF-stream to a file
fname = filename(getName()) + "-" + filename(getDataset().getName()) + ".pdf";
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(fname));
for (int i = 0; i < folders.size(); i++ ) {
// grab the folder
LIFolder f = (LIFolder) folders.get(i);
if (f == null) continue;
open = true;
break;
}
// we have no valid folders
if (folders.size() > 0 && !open) {
// they selected an empty row
javax.swing.JOptionPane.showMessageDialog(null, BUNDLE.getString("report-none-selected"),
BUNDLE.getString("report-none-selected-title"),
javax.swing.JOptionPane.ERROR_MESSAGE);
return;
}
if (folders.size() == 0) {
// get all folders from dataset
folders = FolderFinder.findAll(getSession(), getDataset());
}
open = false;
for (int i = 0; i < folders.size(); i++ ) {
// grab the folder
LIFolder f = (LIFolder) folders.get(i);
if (f == null) continue;
if (!open) {
open = true;
document.open();
}
