官网的插件开发文档:http://cordova.apache.org/docs/en/latest/guide/hybrid/plugins/index.html

插件文件布局:

比如我在d盘新建了如下的布局

--src

--android

--alert.java

--www

--alert.js

plugin.xml

插件功能：

在前端点击一个按钮，提示alert.

文件内容:

关于plugin.xml文件内容设置可以参考这里http://cordova.apache.org/docs/en/latest/plugin_ref/spec.html

现在我的内容如下：

--><plugin xmlns="http://apache.org/cordova/ns/plugins/1.0"id="alert-plugin"version="1.0.0"><name>AlertPlugin</name><description>显示alert的插件</description><license>Apache 2.0</license><keywords>cordova,AlertPlugin</keywords><engines><engine name="cordova-android" version=">=3.6.0" /><!-- Requires CordovaPlugin.preferences --></engines><js-module src="www/alert.js" ><clobbers target="navigator.alert" /></js-module><!-- android --><platform name="android"><config-file target="res/xml/config.xml" parent="/*"><feature name="alert"><param name="android-package" value="com.alert"/><param name="onload" value="true"/></feature></config-file><source-file src="src/android/alert.java" target-dir="src/com" /></platform>
</plugin>

基础的不说，说下js-module,关于<clobbers>官网上是这样说的

• <clobbers target="some.value"/> indicates that the module.exports is inserted into the windowobject as window.some.value. You can have as many <clobbers> as you like. Any object not available on window is created.

意思是，比如我www下的alert.js文件如下

var exec = require('cordova/exec');var alertPlugin = {show:function(success,error,message) {exec(success, error, "alert", "show", message);}
};module.exports = alertPlugin;

如果我这样配置的话

<js-module src="www/alert.js" ><clobbers target="navigator.alert" /></js-module>

意味着

navigator.alert就代表了alertPlugin

当我们调用alertPlugin.show方法的时候就等同于调用navigator.alert.show方法就行。

<source-file src="src/android/alert.java" target-dir="src/com" />

这个指明了核心类的名称，以及当android项目执行安装的时候，alert.java是会出现在src/com路径下的

 <feature name="alert"><param name="android-package" value="com.alert"/><param name="onload" value="true"/></feature>

value="com.alert"对应了android项目下的com.alert.java文件

<feature name="alert">中的alert和

 cordova.exec(function(winParam) {}, function(error) {}, "service", "action", ["firstArgument", "secondArgument", 42, false]);

中的service名字一样

对于alert.java,内容如下

public class alert extends CordovaPlugin {@Overridepublic boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {if (action.equals("show")) {String message = args.getString(0);this.echo(message, callbackContext);return true;}return false;}private void echo(String message, CallbackContext callbackContext) {if (message != null && message.length() > 0) {AlertDialog.Builder builder = new Builder(cordova.getActivity());builder.setMessage(message);builder.setTitle("提示");callbackContext.success(message);} else {callbackContext.error("Expected one non-empty string argument.");}}
}

注意show是和

cordova.exec(function(winParam) {}, function(error) {}, "service", "action", ["firstArgument", "secondArgument", 42, false]);

中的action名字是一样的。
