ZXING Android嵌入式IntentIntegrator的用法 [英] ZXING Android Embedded Usage of IntentIntegrator

问题描述

我是Android开发的新手，仍然试图掌握一些概念。我发现最好的学习方法是通过项目直接进入深层。话虽如此，这是我的问题：

I am new to Android development and still trying to get the grasp of some of the concepts. I find the best way to learn is to jump right into the deep end with a project. With that said, here is my question:

我已将ZXing Android Embedded集成到我的应用程序中;但是，我无法理解您使用IntentIntegrator的方式。我正在尝试做的就是当用户点击按钮时将QR扫描仪调到屏幕上。我一直试图按照他们的github链接[这里] [1]上的说明但是没有成功。

I have integrated ZXing Android Embedded into my application; however, I am having trouble understanding the way in which you use IntentIntegrator. All I am trying to do at the moment is call the QR scanner to the screen when the user taps a button. I have been trying to follow the instructions on their github link [here][1] but have been unsuccessful.

这是我的功能到目前为止的样子：

Here is what my function looks like so far:

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            IntentIntegrator integrator = new IntentIntegrator(this);
            IntentIntegrator.forFragment(this).initiateScan();

        }

    });

我一直收到错误消息：

错误：（109,25）错误：类
中的构造函数IntentIntegrator IntentIntegrator不能应用于给定类型; required：Activity
found：意图原因：实际参数Intent无法通过方法调用转换转换为
活动

Error:(109, 25) error: constructor IntentIntegrator in class IntentIntegrator cannot be applied to given types; required: Activity found: Intent reason: actual argument Intent cannot be converted to Activity by method invocation conversion

此外，当我将鼠标放在Android Studio中的'（this）'时，它说：

Also, as I put my mouse over '(this)' in Android Studio, it says:

anonymous android.view.View。 onClickListener

anonymous android.view.View.onClickListener

非常感谢任何帮助，谢谢！如果您需要任何其他信息，请告诉我。

Any help would be greatly appreciated, thanks! If you need any other information, please let me know.

推荐答案

以下可以工作：

btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                new IntentIntegrator(getActivity()).initiateScan();
                popupWindow.dismiss();

            }
        });
