# 项目（扫一扫）[QRCodeScan](https://gitee.com/ddgameshop/qrcode-wx)

> ## 基于[微信扫一扫](https://github.com/square/retrofit)、[openCV源码](https://github.com/opencv/opencv)、[opencv_contrib源码](https://github.com/opencv/opencv_contrib)（微信二维码引擎已经开源到openCV分支上）；[openCV源码编译步骤](https://onlyloveyd.blog.csdn.net/article/details/113665108)

## 一、使用依赖


**在module下的build.gradle添加。**

#### 在module下的build.gradle的目录下android{ }加入

    ```
    ndk {
        abiFilters 'armeabi-v7a'
        abiFilters "armeabi"
    }
    repositories {
       flatDir {
          dirs 'libs'
       }
    }

    sourceSets {
        main {
          jniLibs.srcDirs = ['libs']
        }
    }

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    ```

#### 直接引入

    ```
    implementation 'com.gitee.ddgameshop:qrcode-wx:v1.0.0'

    ```

## 二、功能使用

### * 初始化openCV SO库已经是否成功的回调。
    ```
    if (!OpenCVLoader.initDebug()) {
            OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION, this, mLoaderCallback);
    } else {
            mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);
    }

    //opencv库 加载并初始化回调的函数
    private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
        @Override
        public void onManagerConnected(int status) {
            super.onManagerConnected(status);
            if (status == BaseLoaderCallback.SUCCESS) {
                Log.d(TAG, "加载成功");
            } else {
                super.onManagerConnected(status);
                Log.d(TAG, "加载失败");
            }
        }
    };
    ```
### * 调用扫一扫以及结果返回。
    ```
    // 开始扫码
    private void startQrCode() {
        // 申请相机权限
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            // 申请权限
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CAMERA}, Constant.REQ_PERM_CAMERA);
            return;
        }
        // 申请文件读写权限（部分朋友遇到相册选图需要读写权限的情况，这里一并写一下）
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            // 申请权限
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, Constant.REQ_PERM_EXTERNAL_STORAGE);
            return;
        }
        // 二维码扫码
        Intent intent = new Intent(MainActivity.this, CaptureActivity.class);
        startActivityForResult(intent, Constant.REQ_QR_CODE);
    }

    //扫描结果回调
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //扫描结果回调
        if (requestCode == Constant.REQ_QR_CODE && resultCode == RESULT_OK && data != null) {
            Bundle mBundle = data.getExtras();
            if (mBundle != null) {
                String scanResult = mBundle.getString(Constant.INTENT_EXTRA_KEY_QR_SCAN);
                //将扫描出的信息显示出来
                tv_qrcode_result.setText(scanResult);
            }
        }
    }
    ```

## 三、最后

### * 项目的APP module MainActivity.class中有相应的代码。
