android基于ZXing和ZBar的二维码扫描项目

更多： http://www.codefrom.com/p/Android

Android库项目，提供基于ZXing和ZBar易于使用，可扩展的条码扫描器的用法。

ZXing

安装：
添加下面的依赖关系到你的build.gradle文件。

compile 'me.dm7.barcodescanner:zxing:1.7.2'

简单的用法：

1）添加摄像头权限进AndroidManifest.xml文件：

<uses-permission android:name="android.permission.CAMERA" />

2.) A very basic activity would look like this:

public class SimpleScannerActivity extends Activity implements ZXingScannerView.ResultHandler {
    private ZXingScannerView mScannerView;

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);
        mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
        setContentView(mScannerView);                // Set the scanner view as the content view
    }

    @Override
    public void onResume() {
        super.onResume();
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
        mScannerView.startCamera();          // Start camera on resume
    }

    @Override
    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();           // Stop camera on pause
    }

    @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here
        Log.v(TAG, rawResult.getText()); // Prints scan results
        Log.v(TAG, rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)
    }
}

ZBar

安装

添加下面的依赖关系到你的build.gradle文件。

compile 'me.dm7.barcodescanner:zbar:1.7.2'

简单用法
1) Add camera permission to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.CAMERA" />

2.) A very basic activity would look like this:

public class SimpleScannerActivity extends Activity implements ZBarScannerView.ResultHandler {
    private ZBarScannerView mScannerView;

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);
        mScannerView = new ZBarScannerView(this);    // Programmatically initialize the scanner view
        setContentView(mScannerView);                // Set the scanner view as the content view
    }

    @Override
    public void onResume() {
        super.onResume();
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
        mScannerView.startCamera();          // Start camera on resume
    }

    @Override
    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();           // Stop camera on pause
    }

    @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here
        Log.v(TAG, rawResult.getContents()); // Prints scan results
        Log.v(TAG, rawResult.getBarcodeFormat().getName()); // Prints the scan format (qrcode, pdf417 etc.)
    }
}
