封装的二维码条形码扫描,二维码生成，识别图片中二维码的类库

二维码在生活中非常的普遍，这个库基于最新的Google ZXing 3.3.2jar包来实现

使用方法:

1.在项目的project 目录下的build.gradle 中的allprojects加上 maven { url 'https://jitpack.io' }

allprojects { repositories { jcenter() maven { url 'https://maven.google.com' } maven { url 'https://jitpack.io' } } }

2.在自己项目的module中的build.gradle目录下，加上 compile 'com.github.doctorji:zxinglib:V1.0'

public class MainActivity extends BaseActivity { private TextView resultTextView; private EditText qrStrEditText; private ImageView qrImgImageView; private CheckBox mCheckBox;

@Override
public void saveInstance(Bundle savedInstanceState) {

}

@Override
public void initParms(Bundle parms) {

}

@Override
public int bindLayout() {
    return R.layout.activity_main;
}

@Override
public void doBusiness(final Context mContext) {
    resultTextView = (TextView) this.findViewById(R.id.tv_scan_result);
    qrStrEditText = (EditText) this.findViewById(R.id.et_qr_string);
    qrImgImageView = (ImageView) this.findViewById(R.id.iv_qr_image);
    mCheckBox = (CheckBox) findViewById(R.id.logo);

    TextView tvscanBarCode = (TextView) this.findViewById(R.id.tv_scan_barcode);
    tvscanBarCode.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //打开扫描界面扫描条形码或二维码
            requestPermissions(mContext, new String[]{"android.permission.CAMERA", "android.permission.READ_CONTACTS", "android.permission.WRITE_EXTERNAL_STORAGE"}, new RequestPermissionCallBack() {
                @Override
                public void granted() {
                    Intent openCameraIntent = new Intent(MainActivity.this, CaptureActivity.class);
                    startActivityForResult(openCameraIntent, 0);
                }

                @Override
                public void denied() {
                    Toast.makeText(mContext, "请同意以上授权请求", Toast.LENGTH_LONG).show();
                }
            });

        }
    });

    TextView generateQRCodeButton = (TextView) this.findViewById(R.id.tv_add_qrcode);
    generateQRCodeButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            String contentString = qrStrEditText.getText().toString();
            if (!contentString.equals("")) {
                //根据字符串生成二维码图片并显示在界面上，第二个参数为图片的大小（350*350）
                Bitmap qrCodeBitmap = EncodingUtils.createQRCode(contentString, 350, 350,
                        mCheckBox.isChecked() ?
                                BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher) :
                                null);
                qrImgImageView.setImageBitmap(qrCodeBitmap);
            } else {
                Toast.makeText(MainActivity.this, "输入内容不能为空", Toast.LENGTH_SHORT).show();
            }
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        Bundle bundle = data.getExtras();
        String scanResult = bundle.getString("result");
        resultTextView.setText(scanResult);
    }
}

}

主要是在调用类库里面的CaptureActivity.class 扫描条形码和二维码的功能

生成二维码 封装成了一个util EncodingUtil
