集成默认的二维码扫描页面

Posted 2021-01-11 monkey0928

1.在module的build.gradle中执行compile操作

compile ‘cn.yipianfengye.android:zxing-library:2.2‘

2.在demo Application中执行初始化操作

@Override
    public void onCreate() {
        super.onCreate();

        ZXingLibrary.initDisplayOpinion(this);
    }

3.在代码中执行打开扫描二维码界面操作

  Intent intent = new Intent(MainActivity.this, CaptureActivity.class);
  startActivityForResult(intent, REQUEST_CODE);
//这里的REQUEST_CODE是我们定义的int型常量

4.在Activity的onActivityResult方法中接收扫描结果

/**
         * 处理二维码扫描结果
         */
        if (requestCode == REQUEST_CODE) {
            //处理扫描结果（在界面上显示）
            if (null != data) {
                Bundle bundle = data.getExtras();
                if (bundle == null) {
                    return;
                }
                if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_SUCCESS) {
                    String result = bundle.getString(CodeUtils.RESULT_STRING);
                    Toast.makeText(this, "解析结果:" + result, Toast.LENGTH_LONG).show();
                } else if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_FAILED) {
                    Toast.makeText(MainActivity.this, "解析二维码失败", Toast.LENGTH_LONG).show();
                }
            }
        }
