ZXing Barcode Scanner Android library

Note: This software is now in the public domain. I have no further use for it, so it is EOL-ed. (However if you use it, I'd love to see what you do with it)

This allows for you to directly embed ZXing into your application properly.

Please note: This does not contain enough (any more) to work as the normal ZXing application on it's own. Resources are missing and it will look crap. (The CaptureActivity and other stuff is to be removed when I get round to doing it).

Why?

For my coursework, I have an Android app that uses barcode scanning but I want to make it seamless where I scan an item then an ID card without leaving the app.

Setup

Once cloned, you will need to deploy it via Maven. This is done by running mvn clean install.

In your application add it to pom.xml:

    <dependency>
        <groupId>com.google.zxing</groupId>
        <artifactId>android-lib</artifactId>
        <version>2.1</version>
        <type>apklib</type>
    </dependency>

If someone is a really nice person, they could deploy it to Maven Central (i have no idea).

How to use

You should only require the use of classes (my code) locaed in namespace zxing.library.

Everything is modernized into a Fragment, so you can add it to your layout like so:

<fragment class="zxing.library.ZXingFragment"
        android:id="@+id/scanner"
        android:layout_width="match_parent" android:layout_height="match_parent" />

And by accessing the Fragment instance itself you can use setDecodeCallback() to set a new callback to fall down onto.

Also, in the callback you will need to ask the fragment to start rescanning using restartScanning() or restartScanningIn( <value-in-milliseconds> ). Like so:

final ZXingFragment xf = (ZXingFragment) getSupportFragmentManager().findFragmentById(R.id.scanner);
    xf.setDecodeCallback(new DecodeCallback(){

		@Override
		public void handleBarcode(Result result, Bitmap arg1, float arg2) {
			Toast.makeText(HelloAndroidActivity.this, result.getText(), Toast.LENGTH_LONG).show();
			xf.restartScanningIn(200);
		}
    	
    });

TODO

• Make the viewfinder in the right place (modifying the way it gets height/width).
• Remove un-needed code
• Deploy to Maven Central somehow
