Adding the Plugin to your project
1. Add the 'LibraryProject' into Eclipse. File -> New Android Project -> create project from existing source.
2. In the new project you've just added to Eclipse go to the project properties. Select the Android section and at the bottom of the dialog check the "Is Library" checkbox.
3. In your application go into the project properties. In the Android section under library click the Add button and select the library you created in step 2.
4. To install the plugin, move barcodescanner.js to your project's www folder and include a reference to it in your html files.
5. Create a folder called 'com/phonegap/plugins/barcodescanner' within your project's src folder.
6. And copy the BarcodeScanner.java file into that new folder.
`mkdir <your_project>/src/com/phonegap/plugins/barcodescanner`
`cp ./src/com/phonegap/plugins/barcodescanner/BarcodeScanner.java <your_project>/src/com/phonegap/plugins/barcodescanner`
7. In your res/xml/plugins.xml file add the following line:
`<plugin name="BarcodeScanner" value="com.phonegap.plugins.barcodescanner.BarcodeScanner"/>`
8. Add the following activity to your AndroidManifest.xml file. It should be added inside the <application/> tag.
`<!-- ZXing activities -->
<activity android:name="com.google.zxing.client.android.CaptureActivity"
android:screenOrientation="landscape"
android:configChanges="orientation|keyboardHidden"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden">
<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.SCAN"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
<activity android:name="com.google.zxing.client.android.encode.EncodeActivity" android:label="@string/share_name">
<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.ENCODE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>`
使用插件
The plugin creates the object `window.plugins.barcodeScanner` with the method `scan(success, fail)`.
The following barcode types are currently supported:
QR_CODE
DATA_MATRIX
UPC_E
UPC_A
EAN_8
EAN_13
CODE_128
CODE_39
CODE_93
CODABAR
ITF
RSS14
PDF417
RSS_EXPANDED
success and fail are callback functions. Success is passed an object with data, type and cancelled properties. Data is the text representation of the barcode data, type is the type of barcode detected and cancelled is whether or not the user cancelled the scan.
完整的实例:
window.plugins.barcodeScanner.scan( function(result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
}, function(error) {
alert("Scanning failed: " + error);
}
);
创建条形码
The plugin creates the object window.plugins.barcodeScanner with the methodencode(type, data, success, fail).
Supported encoding types:
TEXT_TYPE
EMAIL_TYPE
PHONE_TYPE
SMS_TYPE
完整的示例:
window.plugins.barcodeScanner.encode(BarcodeScanner.Encode.TEXT_TYPE, "http://www.nytimes.com", function(success) {
alert("encode success: " + success);
}, function(fail) {
alert("encoding failed: " + fail);
}
);
