我修改维沙尔Rajpal(该ExtractZipFile插件的作者)code遵守科尔多瓦插件结构,记录在的和开发在Android 的一个插件。
I modified Vishal Rajpal (the author of the ExtractZipFile plugin) code to comply with the cordova plugin structure, as documented in Plugin Development Guide and Developing a Plugin on Android.
的Java code 被放在src目录下的组织/阿帕奇/科尔多瓦/插件/ ExtractZipFilePlugin.java
Java code to be put in the src directory under org/apache/cordova/plugin/ExtractZipFilePlugin.java

插件声明被放在RES下插件/ XML / config.xml中

<plugin name="ZipPlugin" value="org.apache.cordova.plugin.ExtractZipFilePlugin" />
JavaScript的code 要包含在你的项目 - 文件ZipPlugin.js

var ExtractZipFilePlugin = function()
{
};
ExtractZipFilePlugin.prototype.extractFile = function(file, successCallback, errorCallback)
{
cordova.exec(successCallback, errorCallback, "ZipPlugin", "unzip", [file]);
};
使用示例
var ZipClient = new ExtractZipFilePlugin();
ZipClient.extractFile("my_path/my.zip", win, fail);
function win(status)
{
alert('Success ' + status);
}
function fail(error)
{
alert(error);
}
