您已将Zxing扫描仪成功集成到我的应用程序中，但我遇到的问题是它不想扫描条形码，但它可以完美地扫描qr代码。当我打开Zxing应用程序时，条形码扫描仪可以工作。当我从我正在构建的应用程序启动它时它才起作用。有没有人以前遇到过这个问题并找到解决方案？
static final String ACTION_SCAN = "com.google.zxing.client.android.SCAN";
//product barcode mode
public void scanBar(View v) {
try {
Intent intent = new Intent(ACTION_SCAN);
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} catch (ActivityNotFoundException anfe) {
//on catch, show the download dialog
showDialog(BarcodeScanner.this, "No Scanner Found", "Download a scanner code activity?", "Yes", "No").show();
}
}
// start qr stuff //product qr code mode
public void scanQR(View v) {
try {
//start the scanning activity from the com.google.zxing.client.android.SCAN intent
Intent intent = new Intent(ACTION_SCAN);
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
} catch (ActivityNotFoundException anfe) {
//on catch, show the download dialog
showDialog(BarcodeScanner.this, "No Scanner Found", "Download a scanner code activity?", "Yes", "No").show();
}
}
//alert dialog for downloadDialog
private static AlertDialog showDialog(final Activity act, CharSequence title, CharSequence message, CharSequence buttonYes, CharSequence buttonNo) {
AlertDialog.Builder downloadDialog = new AlertDialog.Builder(act);
downloadDialog.setTitle(title);
downloadDialog.setMessage(message);
downloadDialog.setPositiveButton(buttonYes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
Uri uri = Uri.parse("market://search?q=pname:" + "com.google.zxing.client.android");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
try {
act.startActivity(intent);
} catch (ActivityNotFoundException anfe) {
}
}
});
downloadDialog.setNegativeButton(buttonNo, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
}
});
return downloadDialog.show();
}
//on ActivityResult method
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
//get the extras that are returned from the intent
String tagNo = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
MySOAPCallActivity cs = new MySOAPCallActivity();
//tagNo = editTagNumber.getText().toString();
final GlobalClass globalVariable = (GlobalClass) getApplicationContext();
// Get name and email from global/application context
String eventName = globalVariable.getEventName();
if(Local.isSet(getApplicationContext(), "EventName"))
{
eventName = Local.Get(getApplicationContext(), "EventName");
}
if(eventName.length() > 0) {
TagParams params = new TagParams(cs, tagNo, eventName);
//Make yes no buttons visible
Button buttonYes = (Button)findViewById(R.id.buttonYes);
Button buttonNo = (Button)findViewById(R.id.buttonNo);
buttonYes.setVisibility(View.VISIBLE);
buttonNo.setVisibility(View.VISIBLE);
TextView nameSurname = (TextView) findViewById(R.id.nameSurname);
nameSurname.setText("");
TextView idNumber = (TextView) findViewById(R.id.idNumber);
idNumber.setText("");
TextView ticketClass = (TextView) findViewById(R.id.ticketClass);
ticketClass.setText("");
new CallSoapTicketValidForEvent().execute(params);
}

尝试以下可能对您有用。
如果您对扫描代码有开放意图，请指定代码格式，如下所示：
intent.putExtra("SCAN_FORMATS", "CODABAR");
以下是格式列表：
/** QR Code 2D barcode format. */
public static final BarcodeFormat QR_CODE = new BarcodeFormat("QR_CODE");
/** DataMatrix 2D barcode format. */
public static final BarcodeFormat DATA_MATRIX = new BarcodeFormat("DATA_MATRIX");
/** UPC-E 1D format. */
public static final BarcodeFormat UPC_E = new BarcodeFormat("UPC_E");
/** UPC-A 1D format. */
public static final BarcodeFormat UPC_A = new BarcodeFormat("UPC_A");
/** EAN-8 1D format. */
public static final BarcodeFormat EAN_8 = new BarcodeFormat("EAN_8");
/** EAN-13 1D format. */
public static final BarcodeFormat EAN_13 = new BarcodeFormat("EAN_13");
/** UPC/EAN extension format. Not a stand-alone format. */
public static final BarcodeFormat UPC_EAN_EXTENSION = new BarcodeFormat("UPC_EAN_EXTENSION");
/** Code 128 1D format. */
public static final BarcodeFormat CODE_128 = new BarcodeFormat("CODE_128");
/** Code 39 1D format. */
public static final BarcodeFormat CODE_39 = new BarcodeFormat("CODE_39");
/** Code 93 1D format. */
public static final BarcodeFormat CODE_93 = new BarcodeFormat("CODE_93");
/** CODABAR 1D format. */
public static final BarcodeFormat CODABAR = new BarcodeFormat("CODABAR");
/** ITF (Interleaved Two of Five) 1D format. */
public static final BarcodeFormat ITF = new BarcodeFormat("ITF");
/** RSS 14 */
public static final BarcodeFormat RSS14 = new BarcodeFormat("RSS14");
/** PDF417 format. */
public static final BarcodeFormat PDF417 = new BarcodeFormat("PDF417");
/** RSS EXPANDED */
public static final BarcodeFormat RSS_EXPANDED = new BarcodeFormat("RSS_EXPANDED");
