worklight 中添加时间控件

在我们使用worklight开发的过程中，由于文档的不开源和插件的缺少，总是自己琢磨很多东东，更有胜者

需要调用源代码实现某些不易实现的功能。在这里把实现的功能代码贴出来，如有不足之处还望指正！

实现的步骤就不多说了，上篇中已经解说

实现日期插件

  1 public class DatePickerPlugin extends CordovaPlugin {
  2 
  3         private static final CordovaActivity ctx = null;
  4         private static final String ACTION_DATE = "date";  
  5         private static final String ACTION_TIME = "time";
  6         
  7         @Override
  8         public boolean execute(String action, JSONArray args,
  9                 CallbackContext callbackContext) throws JSONException {
 10             Log.d("DatePickerPlugin", "Plugin Called");  
 11             PluginResult result = null;  
 12             if (ACTION_DATE.equalsIgnoreCase(action)) {  
 13                 Log.d("DatePickerPluginListener execute", ACTION_DATE);  
 14                 this.showDatePicker(callbackContext.getCallbackId(),callbackContext);  
 15                 result= new PluginResult(  
 16                         PluginResult.Status.NO_RESULT);  
 17                 result.setKeepCallback(true);  
 18             } else if (ACTION_TIME.equalsIgnoreCase(action)) {  
 19                 Log.d("DatePickerPluginListener execute", ACTION_TIME);  
 20                 this.showTimePicker(callbackContext.getCallbackId(),callbackContext);  
 21                 result = new PluginResult(  
 22                         PluginResult.Status.NO_RESULT);  
 23                 result.setKeepCallback(true);  
 24             } else {  
 25                 result = new PluginResult(Status.INVALID_ACTION);

103                                     callbackContext.sendPluginResult(new PluginResult(  
104                                             PluginResult.Status.OK, userChoice));
105       
106                                 }  
107                             }, mYear, mMonth, mDay);  
108       
109                     dpd.show();  
110                 }  
111             };  
112             this.cordova.getActivity().runOnUiThread(runnable);
113         }
114     }

当然的必须将实现类配置在config.xml中

 1 var DatePicker = function() {  
 2 }; 
 3 DatePicker.prototype.showDateOrTime = function(action,successCallback, failureCallback) {
 4     cordova.exec(   
 5         successCallback,
 6         failureCallback,       
 7         'DatePickerPlugin',  //Tell PhoneGap to run "DatePickerPlugin" Plugin  
 8         action,              //Tell plugin, which action we want to perform  
 9         []        //paramter
10     );        //Passing list of args to the plugin  
11 }; 
12 cordova.addConstructor(function(){
13     //如果不支持window.plugins,则创建并设置  
14     if(!window.plugins){  
15         window.plugins={};  
16     } 
17     window.plugins.datePickerPlugin=new DatePicker(); 
18     cordova.addPlugin('datePickerPlugin', new DatePicker());
19     PluginManager.addService("DatePickerPlugin",  
20     "cn.gcsts.plugin.DatePickerPlugin");  
21 });
