如何在Android中将位图转换为PDF格式

您可以通过这种方式执行…您必须下载itextpdf-5.3.2.jar文件并将其附加到您的项目中。

public class WritePdfActivity extends Activity {  private static String FILE = "mnt/sdcard/FirstPdf.pdf";  static Image image;  static ImageView img;  Bitmap bmp;  static Bitmap bt;  static byte[] bArray;  @Overridepublic void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);    setContentView(R.layout.main);    img=(ImageView)findViewById(R.id.imageView1);    try     {        document document = new document();        PdfWriter.getInstance(document, new FileOutputStream(FILE));        document.open();        addImage(document);        document.close();    }    catch (Exception e)     {        e.printStackTrace();    }}  private static void addImage(document document)   {    try     {        image = Image.getInstance(bArray);  ///Here i set byte array..you can do bitmap to byte array and set in image...    }     catch (BadElementException e)     {        // TODO Auto-generated catch block        e.printStackTrace();    }    catch (MalformedURLException e)     {        // TODO Auto-generated catch block        e.printStackTrace();    }    catch (IOException e)     {        // TODO Auto-generated catch block        e.printStackTrace();    }     // image.scaleAbsolute(150f, 150f);      try       {        document.add(image);    } catch (documentException e) {        // TODO Auto-generated catch block        e.printStackTrace();    } } }
