我正在编写一个应用程序以将 CalDav 和 SyncML 日历添加到日历提供程序数据库中，我可以添加它们，但我遇到了问题，因为当我重新启动时，我的日历消失了。

这是我添加日历的代码

private final CalendarEnvironmentProjection calEP = new CalendarEnvironmentProjection();

public long addCal(ContentResolver cr, String userName, String url,
            String accountType, String timeZone) {

        Log.v(DEBUG_TAG, "Start addCal");
        ContentValues values = new ContentValues();
        String accountName = userName + "@" + url.split("/")[2];
        Log.v(DEBUG_TAG, "Add values");
        values.put(
                this.calEP.eventProj(this.calEP.PROJECTION_SYNC_ACCOUNT_INDEX),
                accountName);
        values.put(this.calEP
                .eventProj(this.calEP.PROJECTION_SYNC_ACCOUNT_TYPE_INDEX),
                accountType);
        values.put(this.calEP.eventProj(this.calEP.PROJECTION_SYNC_NAME_INDEX),
                userName + " Calendar's");
        values.put(
                this.calEP.eventProj(this.calEP.PROJECTION_DISPLAY_NAME_INDEX),
                userName + " Calendar's");
        values.put(this.calEP.eventProj(this.calEP.PROJECTION_SYNC_ID_INDEX),
                url);
        values.put(
                this.calEP.eventProj(this.calEP.PROJECTION_SYNC_DIRTY_INDEX), 1);
        values.put(this.calEP.eventProj(this.calEP.PROJECTION_TIMEZONE_INDEX),
                timeZone);
        values.put(
                this.calEP.eventProj(this.calEP.PROJECTION_OWNER_ACCOUNT_INDEX),
                accountName);
        values.put(this.calEP
                .eventProj(this.calEP.PROJECTION_CALENDAR_ACCESS_LEVEL_INDEX),
                700);
        values.put(
                this.calEP.eventProj(this.calEP.PROJECTION_SYNC_EVENTS_INDEX),
                1);
        values.put(this.calEP
                .eventProj(this.calEP.PROJECTION_CALENDAR_COLOR_INDEX),
                Color.CYAN);

        Log.v(DEBUG_TAG, "Start insert");

        Uri creationUri = asSyncAdapter(
                Uri.parse("content://com.android.calendar/calendars"),
                accountName, accountType);
        Uri uri = cr.insert(creationUri, values);

        Log.v(DEBUG_TAG, "fin insert");
        long calID = Long.parseLong(uri.getLastPathSegment());

        Log.i(this.DEBUG_TAG, "Calendar add: " + calID);
        return calID;
    }

这是我充当 syncAdapter 的代码：

    public CalendarDbAccessors(Context context, boolean autoInitialize) {
    super(context, autoInitialize);

}

@Override
public void onPerformSync(Account account, Bundle extras, String authority,
        ContentProviderClient provider, SyncResult syncResult) {

    Log.i(this.DEBUG_TAG, "onPerformSync()");
}

private Uri asSyncAdapter(Uri uri, String account, String accountType) {
    return uri
            .buildUpon()
            .appendQueryParameter("caller_is_syncadapter", "true")
            .appendQueryParameter(
                    this.calEP
                            .eventProj(this.calEP.PROJECTION_SYNC_ACCOUNT_INDEX),
                    account)
            .appendQueryParameter(
                    this.calEP
                            .eventProj(this.calEP.PROJECTION_SYNC_ACCOUNT_TYPE_INDEX),
                    accountType).build();
}

这是我对数据库进行的投影环境：

public class CalendarEnvironmentProjection {
private String[] eventProj = null;
private final String DEBUG_TAG = "CalendarBD";

private static final String[] EVENT_PROJECTION_8 = new String[] {

"_id", // 0
        "_sync_account", // 1
        "_sync_account_type", // 2
        "name", // 3
        "displayName", // 4
        "_sync_id", // 5
        "_sync_dirty", // 6
        "timezone", // 7
        "ownerAccount", // 8
        "access_level", // 9
        "sync_events", // 10
        "color" // 11

};

@SuppressLint("InlinedApi")
private static final String[] EVENT_PROJECTION_14 = new String[] {

Calendars._ID, // 0
        Calendars.ACCOUNT_NAME, // 1
        Calendars.ACCOUNT_TYPE, // 2
        Calendars.NAME, // 3
        Calendars.CALENDAR_DISPLAY_NAME, // 4
        Calendars._SYNC_ID, // 5
        Calendars.DIRTY, // 6
        Calendars.CALENDAR_TIME_ZONE, // 7
        Calendars.OWNER_ACCOUNT, // 8
        Calendars.CALENDAR_ACCESS_LEVEL, // 9
        Calendars.SYNC_EVENTS, // 10
        Calendars.CALENDAR_COLOR // 11

};

// The indices for the projections arrays above.
protected final int PROJECTION_ID_INDEX = 0;
protected final int PROJECTION_SYNC_ACCOUNT_INDEX = 1;
protected final int PROJECTION_SYNC_ACCOUNT_TYPE_INDEX = 2;
protected final int PROJECTION_SYNC_NAME_INDEX = 3;
protected final int PROJECTION_DISPLAY_NAME_INDEX = 4;
protected final int PROJECTION_SYNC_ID_INDEX = 5;
protected final int PROJECTION_SYNC_DIRTY_INDEX = 6;
protected final int PROJECTION_TIMEZONE_INDEX = 7;
protected final int PROJECTION_OWNER_ACCOUNT_INDEX = 8;
protected final int PROJECTION_CALENDAR_ACCESS_LEVEL_INDEX = 9;
protected final int PROJECTION_SYNC_EVENTS_INDEX = 10;
protected final int PROJECTION_CALENDAR_COLOR_INDEX = 11;

public CalendarEnvironmentProjection() {

    if (Build.VERSION.SDK_INT >= 8 && Build.VERSION.SDK_INT < 14) {
        this.eventProj = EVENT_PROJECTION_8;
    } else if (Build.VERSION.SDK_INT >= 14) {
        this.eventProj = EVENT_PROJECTION_14;
    } else {
        Log.e(this.DEBUG_TAG, "Android version not supported !");

    }

}

protected String[] eventProj() {

    return this.eventProj;
}

protected String eventProj(int projectionIndex) {

    return this.eventProj[projectionIndex];
}}

这是我添加到我的活动中的行：

<intent-filter>
        <action android:name="android.content.SyncAdapter" />
    </intent-filter>
    <meta-data android:name="android.content.SyncAdapter" android:resource="@xml/calendar_sync_adapter" />

这是我在 /res/xml 中的文件：

    <?xml version="1.0" encoding="utf-8"?>
<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
   android:contentAuthority="com.android.calendar"
   android:accountType="com.google"
   android:userVisible="true"
/>
