##Setup ###Maven
<dependency>

<artifactId>mvbarcodereader</artifactId>
<version>LATEST_VERSION</version>
<type>pom</type>
</dependency>###Gradle
compile 'online.devliving:mvbarcodereader:LATEST_VERSION'##Usage ###Scanning Modes
SINGLE_AUTO: The fastest mode. Returns the first barcode it can detect as soon as possible.SINGLE_MANUAL: Detects and highlights all the barcode it can find but returns only the one that user chooses by tapping.MULTIPLE: Detects and highlights all the barcode it can find. Returns all the barcodes on tap.
###Barcode Types You can view this link for a list of supported barcode formats.
###Use the standalone scanner
launch the scanner from your Activity like this:
new MVBarcodeScanner.Builder()
.setScanningMode(mMode)
.setFormats(mFormats)
.build()
.launchScanner(this, REQ_CODE);You'll receive the scanned barcode/barcodes in your Activity's onActivityResult
if (requestCode == REQ_CODE) {
if (resultCode == RESULT_OK && data != null
&& data.getExtras() != null) {
if (data.getExtras().containsKey(MVBarcodeScanner.BarcodeObject)) {
Barcode mBarcode = data.getParcelableExtra(MVBarcodeScanner.BarcodeObject);
} else if (data.getExtras().containsKey(MVBarcodeScanner.BarcodeObjects)) {
List<Barcode> mBarcodes = data.getParcelableArrayListExtra(MVBarcodeScanner.BarcodeObjects);
}
}
}###Use the scanner fragment
You can use the BarcodeCaptureFragment to scan barcodes. Just add the fragment to your Activity
MVBarcodeScanner.ScanningMode mode = null;
@MVBarcodeScanner.BarCodeFormat int[] formats = null;
BarcodeCaptureFragment fragment = BarcodeCaptureFragment.instantiate(mode, formats);
getSupportFragmentManager().beginTransaction()
.add(R.id.container, fragment)
.commit();Then make the the Activity implement the BarcodeCaptureFragment.BarcodeScanningListener so that you can receive results from the fragment or you can set the listener directly to the fragment
fragment.setListener(new BarcodeCaptureFragment.BarcodeScanningListener() {
@Override
public void onBarcodeScanned(Barcode barcode) {
}
@Override
public void onBarcodesScanned(List<Barcode> barcodes) {
}
@Override
public void onBarcodeScanningFailed(String reason) {
}
});
