zxing-android-embedded搬运
github上封装zxing封装的非常好的demo
本来出于尊重原作者,能不搬运就不搬运
但可惜作者已经快一年没管了,有些功能自己做了一些测试性的改动,以及zxing版本的更新等等
还是搬运了吧~
ZXing Android Embedded
Barcode scanning library for Android, using ZXing for decoding.
The project is loosely based on the ZXing Android Barcode Scanner application, but is not affiliated with the official ZXing project.
Features:
Can be used via Intents (little code required).
Can be embedded in an Activity, for advanced customization of UI and logic.
Scanning can be performed in landscape or portrait mode.
Camera is managed in a background thread, for fast startup time.
A sample application is available in Releases.
Adding aar dependency with Gradle
From version 3 this is a single library, supporting Gingerbread and later versions of Android
(API level 9+). If you need support for earlier Android versions, use version 2.
Add the following to your build.gradle file:
repositories {
jcenter()
}
dependencies {
compile 'com.journeyapps:zxing-android-embedded:3.5.0'
compile 'com.android.support:appcompat-v7:23.1.0' // Version 23+ is required
}
android {
buildToolsVersion '23.0.2' // Older versions may give compile errors
}
Usage with IntentIntegrator
Launch the intent with the default options:
new IntentIntegrator(this).initiateScan(); // `this` is the current Activity
// Get the results:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
Use from a Fragment:
IntentIntegrator.forFragment(this).initiateScan(); // `this` is the current Fragment
// If you're using the support library, use IntentIntegrator.forSupportFragment(this) instead.
Customize options:
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);
integrator.setPrompt("Scan a barcode");
integrator.setCameraId(0); // Use a specific camera of the device
integrator.setBeepEnabled(false);
integrator.setBarcodeImageEnabled(true);
integrator.initiateScan();
See IntentIntegrator for more options.
Changing the orientation
To change the orientation, specify the orientation in your AndroidManifest.xml and let the ManifestMerger to update the Activity's definition.
Sample:
android:name="com.journeyapps.barcodescanner.CaptureActivity"
android:screenOrientation="fullSensor"
tools:replace="screenOrientation" />
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.setOrientationLocked(false);
integrator.initiateScan();
Customization and advanced options
For more advanced options, look at the Sample Application,
and browse the source code of the library.
Android Permissions
The camera permission is required for barcode scanning to function. It is automatically included as
part of the library. On Android 6 it is requested at runtime when the barcode scanner is first opened.
When using BarcodeView directly (instead of via IntentIntegrator / CaptureActivity), you have to
request the permission manually before calling BarcodeView#resume(), otherwise the camera will
fail to open.
Building locally
./gradlew assemble
To deploy the artifacts the your local Maven repository:
./gradlew publishToMavenLocal
You can then use your local version by specifying in your build.gradle file:
repositories {
mavenLocal()
}
