Github open source project (Zxing) demo
The fastest call to the Zxing method
1. Related third-party library
2. Call the basic code scan
3. Get the return value
The specific code is as follows:
//1. Default option start intentnew IntentIntegrator().initiateScan(); // `this` is the current Activity
//2. Obtain the result:@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = (requestCode, resultCode, data);
if(result != null) {
if(() == null) {
(this, "Cancel Scan the QR code", Toast.LENGTH_LONG).show();
} else {
(this, "Scan the code result:" + (), Toast.LENGTH_LONG).show();
}
} else {
(requestCode, resultCode, data);
}
}

Translation of IntentIntegrator related method annotation
setCaptureActivity: Set the active class to use. It can be any activity, but should be handled with additional use here.
setPrompt: Set a prompt to display on the capture screen instead of using the default.
setOrientationLocked: By default, the direction is locked. Set to false does not lock.
setCameraId: Use the specified camera ID.
setBeepEnabled: Set to false to disable the beep of scanning.
setBarcodeImageEnabled: set to true so that the barcode image is saved in the result intent and its path is sent.
setDesiredBarcodeFormats: Set the required barcode format scan.
initiateScan: Start scanning all known barcode types with default cameras.
setTimeout: Start scanning all known barcode types with default cameras. And start timer timeout completed
createScanIntent: Create a scan intent with the specified option.
