二維碼 Barcode

引用

這個插件采用的是開源版的 zxing，如果性能、識別率不滿足需求的話，建議使用 Scandit，它提供了 Community SDK，并且支持 Platforms（iOS/Android）、Frameworks（Titanium/Xamarin/Phonegap/Worklight）。其中 Community 版的支持 UPC-A / UPC-E、EAN8 / EAN13、QR Code。

Android 版本的 Zxing 插件默認是橫向掃描的，豎向掃碼需要修改插件的代碼。這里有改好的，可以試試。com.phonegap.plugins.barcodescanner.rar

注意：

a) 沒有實現(xiàn) CONTACT_TYPE 和 LOCATION_TYPE 的 encode。
b) 如果 encode 出錯：

Java 代碼

java.lang.NullPointerException
   at com.google.zxing.client.android.encode.EncodeActivity.onCreateOptionsMenu(EncodeActivity.java:89)

下載最新的 encode.xml 文件，覆蓋 platforms\android\res\menu\encode.xml

Xml 代碼

<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:id="@+id/menu_share"
        android:title="@string/menu_share"
        android:icon="@android:drawable/ic_menu_share"
