我正在为 android 开发一个数字时钟小部件,这是我的代码,但我的问题是我的小部件不见了,我的意思是没有布局,所以有什么帮助吗?首先启用:

public void onEnabled(Context context) {
    super.onEnabled(context);
    PendingIntent anIntent=PendingIntent.getBroadcast(context, 0, new Intent("upp"),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmMgr=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
    alarmMgr.setRepeating(AlarmManager.RTC,System.currentTimeMillis(),1000, anIntent);
} 

然后接收覆盖:

@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getAction().equals("upp")){
        ComponentName componentName =new ComponentName(context,getClass().getName());
        AppWidgetManager appWidgetManager=AppWidgetManager.getInstance(context);
        int[] appWidgetIds=appWidgetManager.getAppWidgetIds(componentName);
        onUpdate(context,appWidgetManager,appWidgetIds);
    }
}

并在更新:

Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {

    super.onUpdate(context, appWidgetManager, appWidgetIds);

然后在 onUpdate 内部,我首先使用 Time 方法将小时和分钟作为字符串:

    onEnabled(context);
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();

int hour = today.hour;
String hh = Integer.toString(hour);

int minute = today.minute;
String mm = ":" + Integer.toString(minute);

然后我用位图在两个图像视图中显示了这两个字符串:

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);

views.setImageViewBitmap(R.id.imageView1, getFontBitmap(context, hh, Color.WHITE, 70));

views.setImageViewBitmap(R.id.imageView2, getFontBitmap1(context, mm, Color.WHITE, 70));

ComponentName componentName =new ComponentName(context,getClass().getName());
int[] appWidgetId=appWidgetManager.getAppWidgetIds(componentName);
appWidgetManager.updateAppWidget(appWidgetId, views);
so any help? Thanks in advance
