我的应用目的仅仅是捕捉一个 ISBN 编号, 然后将 ISBN 转换为字符串 。 我知道 zxing 工程, 但是在擦拭他们的代码和研究后, 我无法找到使用代码的方法, 而不使用意图 。
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "ISBN");
startActivityForResult(intent, 0);
我怎样才能避免这个步骤 使我的应用程序与 条码扫描器应用程序独立开来?
您的问题似乎在于用户设备上存在对 Zxing 条码扫描器的依赖。 正如 Gene 在他的评论中所提到的, Zxing 提供了用于此使用案例的“ Intent Introductor” 库。 这是一个小 Java 库, 您用应用程序捆绑, 处理 Zxing 没有安装在您的电话上的案件, 除其他外 。
