意图发动对Android的时钟应用程序 [英] Intent to launch the clock application on android

问题描述

我现在面临一个问题，一个时钟控件我做。我希望用户能够接触到时钟并启动时钟应用程序在手机上。这是code：

I am facing a problem with a clock widget i made. I want the user to touch the clock and launch the clock app on the phone. this is the code:

//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);
        }

我作出了上述所以，当我接触到的时钟打开报警设置。但是，并不具有普遍性。 我发现，在机器人2.2不起作用。必须有比每一个Android手机的味道，我的世界创造一个if语句更好的解决方案。另外我不知道所有的包名。 任何人都知道如何克服这种请帮助。

I made the above so the when i touch the clock opens the alarm settings. But is not universal. I found out that on droids with 2.2 does not work. There must be a better solution than creating an if statement for every android phone flavor i the world. Plus i don not know the package names for all. Anyone knows how to overcome this please help.

推荐答案

这code适合我的时钟小工具。

This code works for my clock widget.

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
        // ....
}

在这种方式，我可以运行一个默认的时钟管理器。

In this way, I can run a default clock manager.
