Android银行卡扫描获取银行卡号

ard.io开源的银行卡扫描的三方库真的是很好用啊。

首先需要在你的module的gradle的依赖文件中添加依赖

compile 'io.card:android-sdk:5.5.1'

2 清单文件中加入如下activity

<!-- permission to vibrate - recommended, allows vibration feedback on scan -->
 <uses-permission android:name="android.permission.vibrate" />

 <!-- permission to use camera - required -->
 <uses-permission android:name="android.permission.camera" />

 <!-- camera features - recommended -->
 <uses-feature android:name="android.hardware.camera" android:required="false" />
 <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />
 <uses-feature android:name="android.hardware.camera.flash" android:required="false" />

<activity
  android:name="io.card.payment.cardioactivity"  
  android:configchanges="keyboardhidden|orientation" />
<activity android:name="io.card.payment.dataentryactivity" />

3 xml文件中

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 tools:context="com.example.dell.scanbankdemo.mainactivity">

 <button
  android:id="@+id/btn_scan"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:text="扫描银行卡" />

 <textview
  android:id="@+id/tv_card_number"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="银行卡号："
  />
</linearlayout>

全部代码：

public class mainactivity extends appcompatactivity implements view.onclicklistener {
 public static final int my_scan_request_code = 10;

 private button mscanbtn;
 private textview mnumbertv;//银行卡号

 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);
  mscanbtn = findviewbyid(r.id.btn_scan);
  mscanbtn.setonclicklistener(this);
  mnumbertv = findviewbyid(r.id.tv_card_number);
 }

 @override
 public void onclick(view v) {
  switch (v.getid()) {
   case r.id.btn_scan:
    intent scanintent = new intent(this, cardioactivity.class);

    // customize these values to suit your needs.
    scanintent.putextra(cardioactivity.extra_require_expiry, true); // default: false
    scanintent.putextra(cardioactivity.extra_require_cvv, false); // default: false
    scanintent.putextra(cardioactivity.extra_require_postal_code, false); // default: false

    // my_scan_request_code is arbitrary and is only used within this activity.
    startactivityforresult(scanintent, my_scan_request_code);

    break;
  }
 }

 @override
 protected void onactivityresult(int requestcode, int resultcode, intent data) {
  super.onactivityresult(requestcode, resultcode, data);
  if (requestcode == my_scan_request_code) {
   string resultdisplaystr;
   if (data != null && data.hasextra(cardioactivity.extra_scan_result)) {
    creditcard scanresult = data.getparcelableextra(cardioactivity.extra_scan_result);

    // never log a raw card number. avoid displaying it, but if necessary use getformattedcardnumber()
    //resultdisplaystr = "银行卡号: " + scanresult.getredactedcardnumber() + "\n"; //只显示尾号
    resultdisplaystr = "银行卡号: " + scanresult.getformattedcardnumber() + "\n"; //显示银行卡号

    // do something with the raw number, e.g.:
    // myservice.setcardnumber( scanresult.cardnumber );

    if (scanresult.isexpiryvalid()) {
     resultdisplaystr += "有效期：" + scanresult.expirymonth + "/" + scanresult.expiryyear + "\n";
    }

    if (scanresult.cvv != null) {
     // never log or display a cvv
     resultdisplaystr += "cvv has " + scanresult.cvv.length() + " digits.\n";
    }

    if (scanresult.postalcode != null) {
     resultdisplaystr += "postal code: " + scanresult.postalcode + "\n";
    }
   } else {
    resultdisplaystr = "scan was canceled.";
   }
   mnumbertv.settext(resultdisplaystr);
   // do something with resultdisplaystr, maybe display it in a textview
   // resulttextview.settext(resultdisplaystr);
  }
 }
}
