私はアンドロイドアプリをやっています.アプリは16桁のクレジットカード番号と有効期限を読み取って表示します. そのために Card.io を使用しています。アプリはカードを継続的にスキャンしますが、onActivityResult 関数はカード番号と有効期限を表示するために呼び出していません。

私のコードは次のとおりです

import io.card.payment.CardIOActivity;
import io.card.payment.CreditCard;
import org.my.scanExample.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.SlidingDrawer;
import android.widget.TextView;

public class MyScanActivity extends Activity
{
// You MUST register with card.io to get an app token. Go to https://card.io/apps/new/
private static final String MY_CARDIO_APP_TOKEN = "0ac6f74xxxxxxxbefe74e92c7eca"; // My Token number

final String TAG = getClass().getName();

private Button scanButton;
private TextView resultTextView;

private int MY_SCAN_REQUEST_CODE = 100; // arbitrary int

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    resultTextView = (TextView)findViewById(R.id.resultTextView);
    scanButton = (Button)findViewById(R.id.scanButton);

    resultTextView.setText("card.io library version: " + CardIOActivity.sdkVersion() + "\nBuilt: " + CardIOActivity.sdkBuildDate());
}

@Override
protected void onResume() {
    super.onResume();

    if (CardIOActivity.canReadCardWithCamera(this)) {
        scanButton.setText("Scan a credit card with card.io");
    }
    else {
        scanButton.setText("Enter credit card information");
    }
}

public void onScanPress(View v) {
    // This method is set up as an onClick handler in the layout xml
    // e.g. android:onClick="onScanPress"

    Intent scanIntent = new Intent(this, CardIOActivity.class);

    // required for authentication with card.io
    scanIntent.putExtra(CardIOActivity.EXTRA_APP_TOKEN, MY_CARDIO_APP_TOKEN);

    // customize these values to suit your needs.
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: true
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
    scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_ZIP, false); // default: false

    // hides the manual entry button
    // if set, developers should provide their own manual entry mechanism in the app
    scanIntent.putExtra(CardIOActivity.EXTRA_SUPPRESS_MANUAL_ENTRY, false); // default: false

    // MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
    startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);

}

// ここで OnActivityResult は呼び出されません。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    String resultStr;
    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()
        resultStr = "Card Number: " + scanResult.getRedactedCardNumber() + "\n";

        // Do something with the raw number, e.g.:
        // myService.setCardNumber( scanResult.cardNumber );

        if (scanResult.isExpiryValid()) {
            resultStr += "Expiration Date: " + scanResult.expiryMonth + "/" + scanResult.expiryYear + "\n"; 
        }

        if (scanResult.cvv != null) { 
            // Never log or display a CVV
            resultStr += "CVV has " + scanResult.cvv.length() + " digits.\n";
        }

        if (scanResult.zip != null) {
            resultStr += "Zip: " + scanResult.zip + "\n";
        }
    }
    else {
        resultStr = "Scan was canceled.";
    }
    resultTextView.setText(resultStr);

}
}

助けてください..

見逃したのかもしれませんが、コードに問題はありません。問題は XML にある可能性があるため、簡単に説明できると思います。スキャンが完了したら、ユーザーを別のアクティビティに送ります。これを適切な場所にコピーします。新しい xml.file を作成し、これが機能するかどうかを確認します。何か問題があれば教えてください。これは私にとってはうまくいきます。

private Button scanButton;    

}                   
@Override
protected void onResume() {
super.onResume();


if (CardIOActivity.canReadCardWithCamera(this)) {
scanButton.setText("Charge");
}
else {
scanButton.setText("Charge");
}
}
final String TAG = getClass().getName();
private int MY_SCAN_REQUEST_CODE = 100; // arbitrary int            


public void onScanPress(View v) {
// This method is set up as an onClick handler in the layout xml
// e.g. android:onClick="onScanPress"

Intent scanIntent = new Intent(this, CardIOActivity.class);                 

// required for authentication with card.io
scanIntent.putExtra(CardIOActivity.EXTRA_APP_TOKEN, MY_CARDIO_APP_TOKEN);
//Talking points
// customize these values to suit your needs.
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: true
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_ZIP, false); // default: false

// hides the manual entry button
// if set, developers should provide their own manual entry mechanism in the app
scanIntent.putExtra(CardIOActivity.EXTRA_SUPPRESS_MANUAL_ENTRY, false); // default: false

// MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

String resultStr;
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()   ,FYI-getRedactedCardNumber displays partial number.
resultStr = "Card: " + scanResult.getRedactedCardNumber() + "\n";

// Do something with the raw number, e.g.:
// myService.setCardNumber( scanResult.cardNumber );

if (scanResult.isExpiryValid()) {


final TextView xx =(TextView)findViewById(R.id.storeview);
String twox = xx.getText().toString();


Intent intent= new Intent(MyScanActivity.this,WhateverNewActivityYouWant.class)
//Adds the redacted card number
.putExtra("Card Number",resultStr)
startActivity(intent);
finish();


resultStr += "Expiration Date: " + scanResult.expiryMonth + "/" + scanResult.expiryYear + "\n"; 
}
if (scanResult.cvv != null) { 
// Never log or display a CVV
resultStr += "CVV has " + scanResult.cvv.length() + " digits.\n";
}
if (scanResult.zip != null) {
resultStr += "Zip: " + scanResult.zip + "\n";
}
}
else {
resultStr = "Scan was canceled.";
}
resultTextView.setTag(resultStr);




    }}

あなたのWhateverNewActivityYouWant.classでは、インテントを使用したいので

Intent iscool = getIntent();
    if (iscool.getCharSequenceExtra("Card Number") != null) {
    final TextView setmsg = (TextView)findViewById(R.id.resultTextView);
    setmsg.setText(iscool.getCharSequenceExtra("Card Number"));             
    }

whatevernewactivityyouwant.xml

<TextView
    android:id="@+id/resultTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:textSize="16sp" />
