我正在尝试向android日历添加一个事件,并指定该事件将添加到gmail日历中,以便自动与Google日历同步.问题是以编程方式添加的事件不会与Google日历同步,但如果我在手机上添加手动,它会与Google日历同步.我不知道为什么.

这是我用来添加事件的代码:

ArrayList<MyCalendar> calendars = new ArrayList<MyCalendar>();

String[] projection = new String[] { "_id", "name" };
Uri calUri = getCalendarURI(false);
Cursor managedCursor = managedQuery(calUri, projection, "selected=1",
        null, null);

String calName = null;
String calId = null;
if (managedCursor.moveToFirst()) {

    int nameColumn = managedCursor.getColumnIndex("name");
    int idColumn = managedCursor.getColumnIndex("_id");
    do {
        calName = managedCursor.getString(nameColumn);
        calId = managedCursor.getString(idColumn);
        calendars.add(new MyCalendar(Integer.parseInt(calId), calName));
    } while (managedCursor.moveToNext());

}
Toast.makeText(getBaseContext(), calName + "  " + calId,
        Toast.LENGTH_LONG).show();

Calendar cal = Calendar.getInstance();
ContentValues event = new ContentValues();
event.put("calendar_id", …

我正在尝试在屏幕关闭(锁定)时关闭WiFi,并在屏幕打开(解锁)时再次打开它.

我做了一个BroadcastReceiver; 放入清单这段代码:

<receiver android:name="MyIntentReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_OFF" />
                <action android:name="android.intent.action.SCREEN_ON" />
                <action android:name="android.intent.action.USER_PRESENT" />
                <category android:name="android.intent.category.HOME" />
                <category android:name="android.intent.category.LAUNCHER" />    
            </intent-filter>
        </receiver>

这是班级MyIntentReceiver:

package org.androidpeople.boot;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MyIntentReceiver extends BroadcastReceiver {
    // Called when boot completes

    public static boolean startup;

    @Override
    public void onReceive(Context context, Intent intent) {
        // Set what activity should launch after boot completes

        System.out.println("Intent Action: " + intent.getAction());

        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {

            System.out.println("locked …

可能重复:
C#get文件更改事件

我希望在使用C#达到特定大小时跟踪特定文件大小有没有办法在文件大小更改时添加事件处理程序,或者我是否需要在线程中运行无限进程来继续检查文件大小？谢谢

我试图使用此代码以编程方式启动日历同步

Bundle bundle = new Bundle();
bundle.putBoolean(ContentResolver.SYNC_EXTRAS_EXPEDITED, true);
bundle.putBoolean(ContentResolver.SYNC_EXTRAS_FORCE, true);
bundle.putBoolean(ContentResolver.SYNC_EXTRAS_MANUAL, true);
bundle.putBoolean(ContentResolver.SYNC_EXTRAS_IGNORE_SETTINGS, true);

ContentResolver.requestSync(accounts[0], "com.android.calendar", bundle);

我想要一种方式,所以我可以知道同步完成,所以我可以从日历中读取数据,我尝试这样做

while (ContentResolver.isSyncActive(accounts[0], "com.android.calendar")) {
System.out.println("looping: " + i);
}

readLocalCalendar();
readLocalEvents();

但系统在同步结束前退出循环,我仍然可以在状态栏看到同步标志,所以任何帮助,所以我可以在同步完成后阅读日历事件？

谢谢
