意图在android上启动时钟应用程序

我正面临着我制作的时钟小部件的问题.我希望用户触摸时钟并在手机上启动时钟应用程序.这是代码:

//this worked on my nexus 2.1 
if(VERSION.SDK.equals("7")){
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);

            Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.android.deskclock", "com.android.deskclock.DeskClock"));
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, AlarmClockIntent, 0);
            views.setOnClickPendingIntent(R.id.Widget, pendingIntent);

            AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);

        }
  //this worked on my nexus +froyo2.2           
  else if(VERSION.SDK.equals("8")){
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);

            Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.google.android.deskclock", "com.android.deskclock.DeskClock"));
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, AlarmClockIntent, 0);
            views.setOnClickPendingIntent(R.id.Widget, pendingIntent);

            AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);

        }
 //this worked on my htc magic with 1.5 and 1.6
        else{
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);

            Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.android.alarmclock", "com.android.alarmclock.AlarmClock"));
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, AlarmClockIntent, 0);
            views.setOnClickPendingIntent(R.id.Widget, pendingIntent);

            AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
        }

我做了以上所以当我触摸时钟打开警报设置.但不是普遍的.我发现2.2上的机器人不起作用.必须有一个比为世界上每个Android手机风格创建一个if语句更好的解决方案.另外,我不知道所有人的包裹名称.任何人都知道如何克服这个请帮助.

此代码适用于我的时钟小部件.

PackageManager packageManager = context.getPackageManager();
Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);

// Verify clock implementation
String clockImpls[][] = {
        {"HTC Alarm Clock", "com.htc.android.worldclock", "com.htc.android.worldclock.WorldClockTabControl" },
        {"Standar Alarm Clock", "com.android.deskclock", "com.android.deskclock.AlarmClock"},
        {"Froyo Nexus Alarm Clock", "com.google.android.deskclock", "com.android.deskclock.DeskClock"},
        {"Moto Blur Alarm Clock", "com.motorola.blur.alarmclock",  "com.motorola.blur.alarmclock.AlarmClock"},
        {"Samsung Galaxy Clock", "com.sec.android.app.clockpackage","com.sec.android.app.clockpackage.ClockPackage"} ,
        {"Sony Ericsson Xperia Z", "com.sonyericsson.organizer", "com.sonyericsson.organizer.Organizer_WorldClock" },
        {"ASUS Tablets", "com.asus.deskclock", "com.asus.deskclock.DeskClock"}

};

boolean foundClockImpl = false;

for(int i=0; i " + packageName + "/" + className);
        foundClockImpl = true;
    } catch (NameNotFoundException e) {
        debug(vendor + " does not exists");
    }
}

if (foundClockImpl) {
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, alarmClockIntent, 0);
        // add pending intent to your component
        // ....
}

通过这种方式,我可以运行默认的时钟管理器.

为了跟进梅拉的回答,类android.provider.AlarmClock具有正确的Intent这一点,但它可只在API 9级以上.(至少有人在谷歌听取这样的请求!)

要从您的小部件启动时钟应用程序,以下代码有效:

Intent openClockIntent = new Intent(AlarmClock.ACTION_SET_ALARM);
openClockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(openClockIntent);
