About

This is a Fragment port of ZBarScanner.

Usage

• Add ZBarFragment in your Activity.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:gravity="center"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

	.......

    <fragment android:name="com.trhura.android.zbar.scanner.ZBarFragment"
              android:id="@+id/scan_fragment"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"/>

</LinearLayout>

• Your activity needs to implement ZBarFragment.ResultListener, and override onResult(String result) method.

• Use ZBarFragment.getScanner to get the scanner instance.

public interface ZBarScanner {
    public void startScanning ();
    public void stopScanning ();
    public boolean isScanning ();
    public void setModes(int[] modes);
}

• ZBarFragment will start scanning onStart, you may want to call startScanning / stopScanning methods in your Activity onResume / onPause cycles. See the example app for more details.

• Use setModes function to change scan modes. For example, to scan only QR and code128 barcodes –

        int[] modes = new int[] {ZBarConstants.CODE128, ZBarConstants.QRCODE};
        scanner.setModes(modes);
