phonegap之android原生日历调用
- android日历调用首先第一步我们要添加权限
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
- 接着我们书写js调用接口
var calendar = { add: function (success, data) { exec(success, null, "Calendar", "add", [data]); }, open:function(success, data){ exec(success, null, "Calendar", "open", [data]); } }; module.exports = calendar;
- 这两个方法一个add是后台添加到日历数据库，一个打开日历，然后调用系统日历添加
由于android存在版本兼容我们要添加
if (Build.VERSION.SDK_INT >=8) { calanderURL = "content://com.android.calendar/calendars"; calanderEventURL = "content://com.android.calendar/events"; calanderRemiderURL = "content://com.android.calendar/reminders"; } else { calanderURL = "content://calendar/calendars"; calanderEventURL = "content://calendar/events"; calanderRemiderURL = "content://calendar/reminders"; }
- android的日历存储有多个用户，但是系统默认一般会第一个
Cursor userCursor = cordova.getActivity().getContentResolver() .query(Uri.parse(calanderURL), null, null, null, null); if (userCursor.getCount() > 0) { userCursor.moveToFirst(); calId = userCursor.getString(userCursor.getColumnIndex("_id")); }
- android后台添加日历参数，这个时候我们一般调用phonegap线程写法，不会影响ui
private void Add(final JSONObject sData, final CallbackContext context) { cordova.getThreadPool().execute(new Runnable() { public void run() { try { ContentValues event = new ContentValues(); Log.v(TAG, sData.getString("dtstart")); event.put("calendar_id", calId); event.put(Events.TITLE, sData.getString("title")); event.put(Events.EVENT_LOCATION, sData.getString("location")); event.put(Events.DESCRIPTION, sData.getString("description")); event.put(Events.DTSTART, sData.getLong("dtstart")); event.put(Events.DTEND, sData.getLong("dtend")); event.put("eventTimezone", TimeZone.getDefault().getID()); Uri url = cordova.getActivity().getContentResolver() .insert(Uri.parse(calanderEventURL), event); long id = Long.parseLong(url.getLastPathSegment()); ContentValues values = new ContentValues(); values.put("event_id", id); // 提前10分钟有提醒 values.put("minutes", 10); values.put("method", 1); cordova.getActivity().getContentResolver() .insert(Uri.parse(calanderRemiderURL), values); } catch (JSONException e) { e.printStackTrace(); } context.success(); // Thread-safe. } }); }
- 如何调用android弹出系统添加页面了
private void Open() { Uri uri = Uri.parse(calanderEventURL); Intent intent = new Intent("android.intent.action.INSERT", uri); lastId = GetLastId(); cordova.startActivityForResult((CordovaPlugin) this, intent, 1); }
- 因为调用系统添加日历我们无法知道我们添加的状态，我们只能判断日历事件表最大id的是否变化
- 接下来提供详细java代码
