整合ZXing无需使用第三方扫描器的？

问题描述

我读过无数话题已经在那里的人问到如何ZXing在Android应用程序集成，他们不一定需要安装才能扫描QR code第三方扫描应用程序。

I've read numerous topics already where people asked how to integrate ZXing in an Android application where they necessarily need to have a 3rd party scanner app installed in order to scan a QR Code.

这正是我想做的事情了。这是我迄今所做的：

That's exactly what i want to do too. This is what i have done so far:

我下载斑马线项目。我复制了所有相关的源$ C ​​$ C到我的Andr​​oid应用程序。到目前为止好，这一切编译罚款。当我美元，我的应用程序一个按钮p $ PSS它会打开一个小对话框，询问code扫描我想用什么样吧。我有以下选择：

I downloaded the ZXing project. I copied all the relevant source code to my Android application. So far so good, it all compiles fine. When i press on a button in my app it opens a small dialog asking what barcode scanner i want to use. I have the following options:

1. QR-的Droid（第三方应用程序）


2. 我自己的应用程序

当我使用第一个选项，然后相机被激活，我可以扫描QR code。但是当我使用第二个选项（我自己的应用程序），然后什么happends。我以为ZXing想出了一个扫描仪也使第三方QR扫描没有必要？

When i use the first option, then the camera gets activated and i can scan a QR code. But when i use the 2nd option (my own app), then nothing happends. I thought ZXing came with a scanner too, so that a 3rd party QR scanner isn't necessary??

但也许还有其他的步骤，我必须采取藏汉？这是我的表现怎么是这样的：

But maybe there are other steps i have to take aswell? This is how my manifest looks like:

补充这一点：

<intent-filter>
    <action android:name="com.google.zxing.client.android.SCAN"/>
    <category android:name="android.intent.category.DEFAULT"/>
</intent-filter>

而在一个按钮动作，我有：

And in a button action i have:

Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);

有没有什么办法让无需第三方扫描仪的QR扫描的开始？我所有的消息在我的项目。

Is there any way to make a QR Scanner start without the need of a 3rd party scanner?? I have all the source imported in my project.

推荐答案

修改您的清单，并添加此

Modify your Manifest and add this

 <activity
            android:configChanges="orientation|keyboardHidden"
            android:name="com.google.zxing.client.android.CaptureActivity"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
            android:windowSoftInputMode="stateAlwaysHidden" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
            <intent-filter >
                <action android:name="com.google.zxing.client.android.SCAN" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

还添加了摄像头权限

also add camera permission

<uses-permission android:name="android.permission.CAMERA"/>

和你的活动implemetn的onActivityResult方法

and implemetn onActivityResult method in your Activity

 public void onActivityResult(int requestCode, int resultCode, Intent intent)
    {
        if (requestCode == 0)
        {
            if (resultCode == RESULT_OK)
            {
                String contents = intent.getStringExtra("SCAN_RESULT");
                String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
                Log.i("xZing", "contents: "+contents+" format: "+format);
                // Handle successful scan
            }
            else if (resultCode == RESULT_CANCELED)
            {
                // Handle cancel
            }
        }
    }
