如何格式化NDEF格式的NFC标签

Question

我有一个Mifare Classic1K NFC标签,但我无法在上面写任何内容.它的可写但似乎没有在NDEF中格式化,这是Android设备在其上写入数据的先决条件.任何建议都是受欢迎的.

PS:我有一个TRF7960射频天​​线,如果它可以帮助格式化它.

给定一个android.nfc.Tag名为的对象tag来格式化它,使用:

    NdefFormatable formatable=NdefFormatable.get(tag);

    if (formatable != null) {
      try {
        formatable.connect();

        try {
          formatable.format(msg);
        }
        catch (Exception e) {
          // let the user know the tag refused to format
        }
      }
      catch (Exception e) {
        // let the user know the tag refused to connect
      }
      finally {
        formatable.close();
      }
    }
    else {
      // let the user know the tag cannot be formatted
    }
