我想显示局部变量@Override
public void onMessageReceived(String from, Bundle data) {
super.onMessageReceived(from, data);
String msg = data.getString("message");
Log.d(TAG,"GCM Message received is "+msg);
// Notifying to user code goes here
notifyUser(getApplicationContext(),msg);
}
public void notifyUser(Context context,String data){
Intent intent = new Intent(context, NotificationActivity.class);
intent.putExtra("data", data);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setAutoCancel(true);
builder.setContentTitle("New Notification");
builder.setContentIntent(pendingIntent);
builder.setContentText(data);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(uri);
notificationManager.notify(countNotification++, builder.build());
Log.v(TAG,"count "+countNotification);
}
的属性，如theme。
这就是我的theme.name看起来像
*ngFor我也尝试使用<ul>
<li *ngFor="#theme of themes">
<span>theme.name</span>
</li>
</ul>
，但这也不起作用。
答案 0 :(得分：2)
如果
{{theme.name}}
不起作用，然后
{{theme?.name}}
可能会
