Android 二维码扫描工具 QRCodeReaderView

QRCodeReaderView 是基于 ZXING 条形码扫描工具项目改进，为了在肖像模式和增强现实目的下进行更简单的 Android 二维码检测。此项目可以在相机的预览中显示是否有二维码。 

用法:

• Create an Activity which implements onQRCodeReadListener, and let implements required methods
• Make sure Activity orientation is PORTRAIT and give Camera permision in the manifest.xml
• Add a "QRCodeReaderView" in the layout editor like you actually do with a button for example

 <com.dlazaro66.qrcodereaderview.QRCodeReaderView        android:id="@+id/qrdecoderview"         android:layout_width="match_parent"         android:layout_height="match_parent" />

• In your onCreate method, you can find the view as usual, using findViewById() function.
• Set onQRCodeReadListener to the QRCodeReaderView.
• Start & Stop camera preview in onPause() and onResume() overriden methods.
• Use onQRCodeReadListener callbacks as you want.
• You can place widgets or views over QRDecoderView

  public class DecoderActivity extends Activity implements OnQRCodeReadListener {    private TextView myTextView;    private QRCodeReaderView mydecoderview;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_decoder);        mydecoderview = (QRCodeReaderView) findViewById(R.id.qrdecoderview);        mydecoderview.setOnQRCodeReadListener(this);        myTextView = (TextView) findViewById(R.id.exampleTextView);    }    // Called when a QR is decoded    // "text" : the text encoded in QR    // "points" : points where QR control points are placed    @Override    public void onQRCodeRead(String text, PointF[] points) {        myTextView.setText(text);    }    // Called when your device have no camera    @Override    public void cameraNotFound() {    }    // Called when there's no QR codes in the camera preview image    @Override    public void QRCodeNotFoundOnCamImage() {    }    @Override    protected void onResume() {        super.onResume();        mydecoderview.getCameraManager().startPreview();    }    @Override    protected void onPause() {        super.onPause();        mydecoderview.getCameraManager().stopPreview();    }}
