phonegap之android原生日曆調用

• android日曆調用首先第一步咱們要添加權限

  <uses-permission android:name="android.permission.READ_CALENDAR" />
    <uses-permission android:name="android.permission.WRITE_CALENDAR" />

• 接着咱們書寫js調用接口

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;

• 這兩個方法一個add是後臺添加到日曆數據庫，一個打開日曆，而後調用系統日曆添加

因爲android存在版本兼容咱們要添加

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的日曆存儲有多個用戶，可是系統默認通常會第一個

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後臺添加日曆參數，這個時候咱們通常調用phonegap線程寫法，不會影響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);
                    // 提早10分鐘有提醒
                    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.
            }
        });
    }

• 如何調用android彈出系統添加頁面了

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);
        
    }

• 由於調用系統添加日曆咱們沒法知道咱們添加的狀態，咱們只能判斷日曆事件表最大id的是否變化
• 接下來提供詳細java代碼
