QrCodeScannerView-Android is a simple tool that can help you decode Qr Code and create a Qr code by content
base on:
https://github.com/zxing/zxing
https://github.com/dlazaro66/QRCodeReaderView
- QrCode Decode
- QrCode Encode
- Switch Camera in Scanning
- Open / stop QrCode scanning function

| setQRDecodingEnabled(boolean qrDecodingEnabled) | Enable decoding,default true | |
| setAutofocusInterval(int times) | Auto focus,default 2s | |
| setOnQRCodeReadListener(OnQRCodeScannerListener onQRCodeScannerListener) | Call back of decode result | need implement |
| setFrontCamera()/setBackCamera() | Default face oritation | need implement |
| setOnCheckCameraPermissionListener(OnCheckCameraPermissionListener listener) | Call back of the Camera permission | need implement |
| switchCameraFace() | Switch the Camera | |
| startCamera() | Start scan Qrcode | should use it in activity.onResume() |
| stopCamera() | Stop scan Qrcode | should use it in activity.onPause() |
| Method | detail | about |
|---|---|---|
| setCoverViewOutsideColor(int colorRes) | Scan rect outside color | |
| setCoverViewCornerColor(int colorRes) | Scan corner color | |
| setCoverViewCorner(int cornerH, int cornerW, boolean isDp) | Scan corner color length and width | |

also you can init UI by this:
<com.qingmei2.library.view.QRCoverView
android:id="@+id/cover"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cornerColor="#0f0"
app:cornerLength="16dp"
app:cornerWidth="3dp"
app:cornerOutside="false"
app:laserVisible="false"
app:laserColor="#0f0"
app:outsideBackgroundColor="#22000000"
app:scanRectHeight="250dp"
app:scanRectWidth="250dp"
/>
public QRCodeEncoder(Activity activity)
//use it in activity:
qrCodeEncoder = new QRCodeEncoder(this); //init
qrCodeEncoder.createQrCode2ImageView(textContent, ivQRCode);
//or
qrCodeEncoder.createQrCode2ImageView(textContent, ivQRCode, R.mipmap.ic_launcher);
| Method | detail | about |
|---|---|---|
| Bitmap createQrCode(String content, int widthAndHeight); | createQrCode | |
| void createQrCode2ImageView(String content, ImageView imageView); | create QrCode into ImageView | |
| also you can add a icon into QrCode Bitmap | ||
| Bitmap createQrCode(String content, int width, int iconRes); | createQrCode with icon | |
| void createQrCode2ImageView(String content, ImageView imageView, int iconRes); | create QrCode with icon into ImageView |
Override Methods:
Result: create_demo_normal create_demo_icon
- QrCodeEncoder The assistant class can help you create a QR code bitmap into ImageView.
- QrCoverView now you can use attributes in your layout.
