Android扫描银行卡获取银行卡号

card.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);
        }
    }
}
