使用Cardme創建VCard Java

Question

嗨 我正嘗試使用Cardme API在Java中創建vcard（.vcf）文件。 我可以保存一個.vcf文件，但它沒有內容並且是空的。 請在下面找到我的代碼，

private void generateVCard(Card card){ 
    HelperClass helper = new HelperClass(); 
    VCardImpl vcard = new VCardImpl(); 
    BeginFeature begin = new BeginFeatureImpl(); 
    vcard.setBegin(begin); 
    vcard.addEmail(helper.formEmailFeature(card)); 
    vcard.addAddress(helper.formAddress(card)); 
    vcard.addPhoto(helper.formPhotoFeature(card)); 
    vcard.addTelephoneNumber(helper.formTelephoneFeature(card)); 
    vcard.setName(helper.formNameFeature(card)); 
    vcard.setFormattedName(helper.formattedName(card)); 
    saveToFile("vc.vcf",vcard); 
} 
/** 
    * This function saves a VCard to disk. 
    */ 
    public void saveToFile(String fileName , VCard vcard) { 
     Writer output = null; 
     File file = new File("fileName"); 
     try { 
     output = new BufferedWriter(new FileWriter(file)); 
     output.write(vcard.toString()); 
      output.flush(); 
      output.close(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    } 

欣賞解決此問題的任何幫助。

需要導入正確的輸出類：

import info.ineighborhood.cardme.io.VCardWriter; 

，或在圖書館（v0.3.3）的包是最新版本：

import net.sourceforge.cardme.io.VCardWriter; 

，然後使用它：

/** 
    * This function saves a VCard to disk. 
    */ 
    public static void saveToFile(String fileName , VCard vcard) { 
    Writer output = null; 
    File file = new File("fileName"); 
    try { 
     output = new BufferedWriter(new FileWriter(file)); 
     VCardWriter writer = new VCardWriter(); 
     writer.setVCard(vcard); 
     output.write(writer.buildVCardString()); 
     output.flush(); 
     output.close(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    }
