card.io開源的銀行卡掃描的三方庫真的是很好用啊。
首先需要在你的module的gradle的依賴文件中添加依賴
compile 'io.card:android-sdk:5.5.1'2 清單文件中加入如下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="掃描銀行卡" />
<TextView
android:id="@+id/tv_card_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="銀行卡號："
/>
</LinearLayout>
全部代碼：
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
public static final int MY_SCAN_REQUEST_CODE = 10;
private Button mScanBtn;
private TextView mNumberTv;//銀行卡號
@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 = "銀行卡號: " + scanResult.getRedactedCardNumber() + "\n"; //只顯示尾號
resultDisplayStr = "銀行卡號: " + scanResult.getFormattedCardNumber() + "\n"; //顯示銀行卡號
// 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);
}
}
}
