android - 打算在Android上启动Clock应用程序

我制作的时钟小部件面临问题。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);
        }

我进行了上述操作，因此当我触摸时钟时会打开闹钟设置。但是不是普遍的。
我发现在使用2.2的droid上不起作用。比为世界上的每个Android手机版本创建if语句，必须有更好的解决方案。再加上我不知道所有的包装名称。
任何人都知道如何克服这个问题，请帮忙。

最佳答案

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<clockImpls.length; i++) {
    String vendor = clockImpls[i][0];
    String packageName = clockImpls[i][1];
    String className = clockImpls[i][2];
    try {
        ComponentName cn = new ComponentName(packageName, className);
        ActivityInfo aInfo = packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA);
        alarmClockIntent.setComponent(cn);
        debug("Found " + vendor + " --> " + 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
        // ....
}

这样，我可以运行默认的时钟管理器。
