Make you have the QRCode Scan ability like WeChat!
C++ port of ZXing for Android
拥有和微信一样的扫码能力！
在gradle中:
// 迁移至 Maven Central
implementation 'io.github.devilsen:czxing:latestVersion'建议加入abiFilters
defaultConfig {
// 其他设置...
ndk {
// 设置支持的so库架构，设置一个可以减小包的大小
abiFilters "armeabi-v7a","arm64-v8a"
}
}如果下载失败，可以在根目录加入阿里云的镜像
maven { url 'https://maven.aliyun.com/repository/central' }注：请先下载 模型 到本地使用
你可以直接使用已经封装好的ScanActivity作为扫码界面
…混淆配置
-keep class me.devilsen.czxing.**
-keep class me.devilsen.czxing.** { *; }或者使用ScanView来自定义你的界面
在自定义的Activity中你需要接管ScanView的生命周期，具体可以参看ScanActivity界面，同时设定setScanListener()
mScanView.setScanListener(new ScanListener() {
@Override
public void onScanSuccess(String result, BarcodeFormat format) {
// 扫码成功
}
@Override
public void onOpenCameraError() {
// 打开相机出错
}
});更多API请参考CustomizeActivity
调用以下代码，可生成二维码的bitmap，Color为可选参数，默认为黑色。
简易调用
BarcodeWriter writer = new BarcodeWriter();
Bitmap bitmap = writer.write("Hello World", BarCodeUtil.dp2px(this, 200), BarCodeUtil.dp2px(this, 200), Color.RED);完整调用
/**
* 生成图片
*
* @param text 要生成的文本
* @param width 图片宽
* @param height 图片高
* @param color 要生成的二维码颜色
* @param format 要生成的条码格式
* @param logo 放在中间的logo
* @return 条码bitmap
*/
private Bitmap write(String text, int width, int height, int color, BarcodeFormat format, Bitmap logo)
// 适当压缩图片
Bitmap bitmap = BitmapUtil.getDecodeAbleBitmap(picturePath);
// 这个方法因为要做bitmap的变换，所以比较耗时，推荐放到子线程执行
CodeResult result = BarcodeReader.getInstance().read(bitmap);
if (result == null) {
Log.d("Scan >>> ", "no code");
return;
} else {
Log.d("Scan >>> ", result.getText());
