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

android:name="io.card.payment.CardIOActivity"

android:configChanges="keyboardHidden|orientation" />

3 xml文件中

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">

android:id="@+id/btn_scan"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="扫描银行卡" />

android:id="@+id/tv_card_number"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="银行卡号："

/>

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);

}

}

}
