第一步：编写插件类 package cn.xuetang.plugin; import android.widget.Toast; import org.apache.cordova.CallbackContext; import org.apache.cordova.CordovaInterface; import org.apache.cordova.CordovaPlugin; import org.json.JSONArray; import org.json.JSONException; /** * Created by Wizzer on 14-8-28. */ public class ToastPlugin extends CordovaPlugin { public ToastPlugin() { } public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException { if (this.cordova.getActivity().isFinishing()) return true; if (action.equals("show")) { this.show(args.getString(0)); } else if (action.equals("showlong")) { this.showlong(args.getString(0)); } else { return false; } callbackContext.success(); return true; } public void show(String message) { Toast.makeText(this.cordova.getActivity(), Toast.LENGTH_SHORT).show(); } public void showlong(String message) { Toast.makeText(this.cordova.getActivity(), message, Toast.LENGTH_LONG).show(); } }

第二步：配置 res/xml/config.xml <feature> <param value="cn.xuetang.plugin.ToastPlugin" /> </feature>

注：这里的 feature name ，要和↓↓面讲的的js文件里一致。

第三步：创建js文件 plugins/toast.js /** * Created by Wizzer on 14-8-28. */ cordova.define("cn.xuetang.plugin.ToastPlugin", function(require, exports, module) { var exec = require('cordova/exec'); module.exports = { /** * 一共5个参数第一个 :成功回调第二个 :失败回调第三个 :将要调用的类的配置名字(在config.xml中配置↑↑) 第四个 :调用的方法名(一个类里可能有多个方法靠这个参数区分) 第五个 :传递的参数以json的格式 */ show: function(message) { exec(null, null, "ToastPlugin", "show", [message]); }, showlong: function(message) { exec(null, null, "ToastPlugin", "showlong", [message]); } }; });

注：js里两个方法，分别对应类中的两个方法

第四步：修改cordova_plugins.js 引用 tocas.js

在module.exports = [ ] 中追加如下代码：

{ "file": "plugins/toast.js", "id": "cn.xuetang.plugin.ToastPlugin", "merges": [ "navigator.toast" ] }

最后：调用 navigator.toast.show("再点击一次退出"); navigator.toast.showlong("再点击一次退出");

Cordova：连续按两次返回键退出程序

/** * Created by Wizzer on 14-8-28. */ var num = 0; var login = { initialize: function () { this.bindEvents(); }, bindEvents: function () { document.addEventListener('backbutton', this.eventBackButton, false); }, eventBackButton: function () { num++; if (num > 1) { navigator.app.exitApp(); } navigator.toast.show("再点击一次退出"); // 3秒后重新计数 var intervalID = window.setInterval(function() { num=0; window.clearInterval(intervalID); }, 3000); } };

Java：乱码字符不能插入MySQL的解决办法

.replaceAll(“[^a-zA-Z_\u4e00-\u9fa5]”, “”)

只剩下中文和英文字母了，悲催。

JAVA：网易微博模拟登陆

网易微博登陆验证，第一次请求使用BASE64加密、第二次请求使用MD5+RSA加密，比较变态，于是使用JAVA+JS相结合的方式，调用其JS方法得到加密字符串。

/core1.7.0.js 是经过处理的，删掉几行在JAVA引用中会报错的浏览器对象。
