一 简介
1.1 ZXing
目前Android扫描二维码，条形码主要用google官方的工具Zxing，支持扫码，相册解码，生成带logo的二维码等功能
Zxing github 示例地址：https://github.com/zxing/zxing
1.2 ZBar
由于zxing是基于java编写的，扫码速度和解析上可能没那么快，但大部分场合足够用。也有基于c/c++的库zbar，需要编译通过才能用，下面是官网，有兴趣的可以编译试试：

1.3 华为ScanKit
目前体验最好的华为统一扫码SDK，基本可以做到秒扫和快速识别，支持多码识别和二维码生成。但该服务必须在华为开发者联盟平台注册应用，配置包名和服务json

二 Zxing使用
2.1 依赖远程zxing库
dependencies {//zxing的core库implementation "com.google.zxing:core:3.5.1"//zxingimplementation "com.google.zxing:zxing-parent:3.5.1"//zxingimplementation 'com.journeyapps:zxing-android-embedded:4.1.0'}或直接使用下面库，目前识别比较快的Zxing库
implementation 'com.journeyapps:zxing-android-embedded:4.3.0'2.2 添加权限
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.FLASHLIGHT" />2.3 调用SDK的扫码页面并返回结果
/*** 跳转到扫码界面扫码*/
private void goScan(){Intent intent = new Intent(MainActivity.this, CaptureActivity.class);startActivityForResult(intent, REQUEST_CODE_SCAN);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);// 扫描二维码/条码回传if (requestCode == REQUEST_CODE_SCAN && resultCode == RESULT_OK) {if (data != null) {//返回的文本内容String content = data.getStringExtra(DECODED_CONTENT_KEY);//返回的BitMap图像Bitmap bitmap = data.getParcelableExtra(DECODED_BITMAP_KEY);}}
}
三 自定义扫码页面

</layout>3.3 ScanActivity.java
public class ScanActivity extends BaseActivity<ActivityScanBinding> {private DecoratedBarcodeView decoratedBarcodeView;@Overrideprotected int getLayoutId() {return R.layout.activity_scan;}@Overridepublic void initData() {decoratedBarcodeView = new DecoratedBarcodeView(this);decoratedBarcodeView.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));decoratedBarcodeView.setStatusText("");decoratedBarcodeView.getViewFinder().setVisibility(View.GONE);decoratedBarcodeView.getCameraSettings().setAutoFocusEnabled(true);mDataBinding.vScanLayout.removeAllViews();mDataBinding.vScanLayout.addView(decoratedBarcodeView);checkCameraPermission();}public final int REQUEST_CAMERA_PERMISSION = 1;private String cameraPermission = Manifest.permission.CAMERA;private void checkCameraPermission() {//检查是否有相机权限if (ContextCompat.checkSelfPermission(this, cameraPermission) != PackageManager.PERMISSION_GRANTED) {//没权限，请求权限ActivityCompat.requestPermissions(this, new String[]{cameraPermission},REQUEST_CAMERA_PERMISSION);} else {//有权限scanLaunch();}}//权限请求回调@Overridepublic void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {super.onRequestPermissionsResult(requestCode, permissions, grantResults);switch (requestCode) {case REQUEST_CAMERA_PERMISSION:if (grantResults != null && grantResults.length > 0&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {//用户同意权限scanLaunch();} else {// 权限被用户拒绝了，可以提示用户,关闭界面等等。Toast.makeText(this, "拒绝权限，请去设置里面手动开启权限", Toast.LENGTH_SHORT).show();}break;}}/*** 开始扫描*/private void scanLaunch() {Collection<BarcodeFormat> formats = Arrays.asList(BarcodeFormat.QR_CODE, BarcodeFormat.CODE_39);decoratedBarcodeView.getBarcodeView().setDecoderFactory(new DefaultDecoderFactory(formats));decoratedBarcodeView.initializeFromIntent(getIntent());decoratedBarcodeView.decodeContinuous(callback);startScanAnimal();}private BarcodeCallback callback = new BarcodeCallback() {@Overridepublic void barcodeResult(BarcodeResult result) {String originalValue = result.getText();if (TextUtils.isEmpty(originalValue)) {// Prevent duplicate scansreturn;}toResult(originalValue);}@Overridepublic void possibleResultPoints(List<ResultPoint> resultPoints) {}};private void toResult(String originalValue) {Intent intent=new Intent(mContext,ScanResultActivity.class);intent.putExtra("result",originalValue);startActivity(intent);}@Overrideprotected void onResume() {super.onResume();decoratedBarcodeView.resume();}@Overrideprotected void onPause() {super.onPause();decoratedBarcodeView.pause();}@Overrideprotected void onDestroy() {super.onDestroy();if (animation != null) {animation.cancel();}}//扫码线动画private Animation animation;private void startScanAnimal() {animation = new TranslateAnimation(0, 0, 0, StatuesBarUtils.getScreenWidth(this) - StatuesBarUtils.dp2px(this, 100));animation.setDuration(2000);animation.setRepeatCount(Animation.INFINITE);//动画的反复次数animation.setFillAfter(true);//设置为true，动画转化结束后被应用//animation.setRepeatMode(ObjectAnimator.RESTART);//重复模式animation.setInterpolator(new LinearInterpolator());mDataBinding.scanLine.startAnimation(animation);//開始动画}
}
四 相册选区图片解析二维码
4.1 选择相册图片
private void setPictureScanOperation() {imgBtn = findViewById(R.id.img_btn);imgBtn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent pickIntent = new Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI);pickIntent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");ZxingActivity.this.startActivityForResult(pickIntent, REQUEST_CODE_PHOTO);}});}4.2 本地图片文件转换成可解码二维码的 Bitmap
/*** 将本地图片文件转换成可解码二维码的 Bitmap。为了避免图片太大，这里对图片进行了压缩。** @param picturePath 本地图片文件路径*/public static Bitmap getDecodeAbleBitmap(String picturePath) {try {BitmapFactory.Options options = new BitmapFactory.Options();options.inJustDecodeBounds = true;BitmapFactory.decodeFile(picturePath, options);int sampleSize = options.outHeight / 400;if (sampleSize <= 0) {sampleSize = 1;}options.inSampleSize = sampleSize;options.inJustDecodeBounds = false;return BitmapFactory.decodeFile(picturePath, options);} catch (Exception e) {e.printStackTrace();return null;}}4.3 解析二维码图片
/*** 同步解析bitmap二维码。该方法是耗时操作，请在子线程中调用。** @param bitmap 要解析的二维码图片* @return 返回二维码图片里的内容 或 null*/public static String syncDecodeQRCode(Bitmap bitmap) {Result result;RGBLuminanceSource source = null;try {int width = bitmap.getWidth();int height = bitmap.getHeight();int[] pixels = new int[width * height];bitmap.getPixels(pixels, 0, width, 0, 0, width, height);source = new RGBLuminanceSource(width, height, pixels);result = new MultiFormatReader().decode(new BinaryBitmap(new HybridBinarizer(source)), new EnumMap<>(DecodeHintType.class));return result.getText();} catch (Exception e) {e.printStackTrace();if (source != null) {try {result = new MultiFormatReader().decode(new BinaryBitmap(new GlobalHistogramBinarizer(source)), new EnumMap<>(DecodeHintType.class));return result.getText();} catch (Throwable e2) {e2.printStackTrace();}}return null;}}五 生成二维码
5.1 效果图，支持修改边框颜色大小，二维码颜色大小，背景颜色，logo样式和圆角
5.2 activity_qrcode_style_xml

}5.4 异步调用QRCodeEncoder生成二维码
private void updateQrcode(){new GenerateQrcodeTask().execute(content);}public class GenerateQrcodeTask extends AsyncTask<String, Void, Bitmap> {@Overrideprotected Bitmap doInBackground(String... strings) {Bitmap logoBitmap=null;if(logo!=0){logoBitmap = BitmapFactory.decodeResource(getResources(), logo);}int borderColor22=TextUtils.isEmpty(borderColor)?0:Color.parseColor(borderColor);return QRCodeEncoder.syncEncodeQRCode(strings[0], (int) StatuesBarUtils.dp2px(mContext, 300f), Color.parseColor(qianColor),Color.parseColor(beinColor),logoBitmap, border , borderColor22);}@Overrideprotected void onPostExecute(Bitmap bitmap) {super.onPostExecute(bitmap);qrBitmap=bitmap;if (bitmap != null) {mDataBinding.vImage.setImageBitmap(qrBitmap);} else {Toast.makeText(mContext, "生成維碼失敗", Toast.LENGTH_SHORT).show();}}}5.5 保存二维码，FileUtil.java工具类
public class FileUtil {public static String saveToImage(Bitmap bitmap) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {return MediaStore.Images.Media.insertImage(MyApp.getInstance().getContentResolver(), bitmap, "", "");} else {try {File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "qrcode");if (!dir.exists()) {dir.mkdirs();}File picFile = new File(dir, System.currentTimeMillis() + ".png");FileOutputStream fos = new FileOutputStream(picFile);bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);fos.flush();fos.close();return picFile.getAbsolutePath();} catch (Exception e) {e.printStackTrace();}}return null;}
异步调用FileUtil，保存二维码
public class SaveBitmapTask extends AsyncTask<Bitmap, Void, String> {@Overrideprotected String doInBackground(Bitmap... bitmaps) {return FileUtil.saveToImage(bitmaps[0]);}@Overrideprotected void onPostExecute(String result) {super.onPostExecute(result);if (result != null) {Intent intent = new Intent(mContext, QrBarcodeEditResultActivity.class);intent.putExtra("filePath", result);startActivity(intent);} else {Toast.makeText(mContext, "保存二維碼失敗", Toast.LENGTH_SHORT).show();}}}5.6 核心源码解析，我们知道bitmap是一个保存所有像素内容的容器，那二维码原理即是把内容解析到每一个像素里面。如下
/**** @param content 要生成的二维码图片内容* @param size 图片宽高，单位为px* @param foregroundColor 二维码图片的前景色* @param backgroundColor 二维码图片的背景色* @param logo 二维码图片的logo* @param borderColor 边框颜色*/
