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);
  }
 }
}
