更改时钟拨号图像

我正在创建一个用于学习目的的模拟时钟小部件,并想知道如何进行设置布局以更改时钟刻度盘图像。我已经完成了小部件,但我似乎无法获得一个onclicklstener来调出设置布局。

这就是我所拥有的:

@Override
public void onDeleted(Context  context, int[] appWidgetIds) 
{super.onDeleted(context, appWidgetIds);
}

@Override
public void onDisabled(Context  context) {
        super.onDisabled(context);
        }

@Override
public void onReceive(Context context, Intent intent)
{
    String action = intent.getAction();
    if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
    {

        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);
    }
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
    int[] appWidgetIds) 
{
        super.onUpdate(context, appWidgetManager, appWidgetIds);
        RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.settings);
        Intent launchActivity = new Intent(context,Widget.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context,0, launchActivity, 0);
        updateViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);
        ComponentName myComponentName = new ComponentName(context, Settings.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(context);
        manager.updateAppWidget(myComponentName, updateViews);
}

}

对于未来的访客:

PendingIntent方法中放置确保设置onUpdate()的代码。这样可以确保只要将小部件放在主屏幕上,就会设置PendingIntent

所以:

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgets) {
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
    Intent intent = new Intent(context, Info.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
    remoteViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);

如果您还希望在首次将小部件添加到主屏幕时自动弹出信息Activity,则应阅读this userful piece of information
