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);
26 Log.d("DatePickerPlugin", "Invalid action : " + action + " passed");
27 }
28 return false;
29 }
30 /**
31 * 时分实现
32 * @param callBackId
33 * @param callbackContext
34 */
35 public synchronized void showTimePicker(final String callBackId,final CallbackContext callbackContext) {
36 final Calendar c = Calendar.getInstance();
37 final int mWhen = c.get(Calendar.HOUR_OF_DAY);
38 final int mMin = c.get(Calendar.MINUTE);
39
40 final Runnable runnable = new Runnable() {
41 public void run() {
42 final TimePickerDialog tpd = new TimePickerDialog(cordova.getActivity(),
43 new OnTimeSetListener() {
44
45 public void onTimeSet(final TimePicker view,
46 final int hourOfDay, final int minute) {
47 final JSONObject userChoice = new JSONObject();
48 try {
49 userChoice.put("hour", hourOfDay);
50 userChoice.put("min", minute);
51 } catch (final JSONException jsonEx) {
52 Log.e("showDatePicker",
53 "Got JSON Exception "
54 + jsonEx.getMessage());
55 callbackContext.sendPluginResult(new PluginResult(
56 Status.JSON_EXCEPTION));
57 }
58 callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK,
59 userChoice));
60 }
61 }, mWhen, mMin, true);
62
63 tpd.show();
64 }
65 };
66 this.cordova.getActivity().runOnUiThread(runnable);
67 }
68 /**
69 * 年月日实现
70 * @param callBackId
71 * @param callbackContext
72 */
73 public synchronized void showDatePicker(final String callBackId,final CallbackContext callbackContext) {
74
75 final Calendar c = Calendar.getInstance();
76 final int mYear = c.get(Calendar.YEAR);
77 final int mMonth = c.get(Calendar.MONTH);
78 final int mDay = c.get(Calendar.DAY_OF_MONTH);
79
80 final Runnable runnable = new Runnable() {
81
82 public void run() {
83 final DatePickerDialog dpd = new DatePickerDialog(cordova.getActivity(),
84 new OnDateSetListener() {
85
86 public void onDateSet(final DatePicker view,
87 final int year, final int monthOfYear,
88 final int dayOfMonth) {
89
90 final JSONObject userChoice = new JSONObject();
91
92 try {
93 userChoice.put("year", year);
94 userChoice.put("month", monthOfYear);
95 userChoice.put("day", dayOfMonth);
96 } catch (final JSONException jsonEx) {
97 Log.e("showDatePicker",
98 "Got JSON Exception "
99 + jsonEx.getMessage());
100 callbackContext.sendPluginResult(new PluginResult(
101 Status.JSON_EXCEPTION, userChoice));
102 }
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 });
效果图展示
worklight 中添加时间控件
