路过小部件ID到活动 [英] Passing widget id to activity

问题描述

在我的部件供应商，我有以下的code：

In my widget provider, I have the following code:

for (int widget_id : appWidgetIds) {
  Log.d(TAG, "Widget Id: " + widget_id);
  RemoteViews remoteViews;

  Widget widget;

  while (true) {
    try {
      widget = Widget.load(context, Widget.class, widget_id);
      break;
    }
    catch (Exception ex) {
      Log.e(TAG, "Exception!", ex);
    }
  }

  // Widget is assigned to user
  if (widget != null) {
    remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_with_user);
    remoteViews.setCharSequence(R.id.user_text, "setText", widget.user.name);
    remoteViews.setUri(R.id.avatar, "setImageURI", Uri.parse(widget.user.avatar));
  }
  else {
    remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
    Intent configIntent = new Intent(context, ConfigureWidget.class);
    configIntent.setAction(ACTION_WIDGET_CONFIGURE);
    configIntent.putExtra("widget_id", widget_id);

    PendingIntent configPendingIntent = PendingIntent.getActivity(context, REQUEST_CODE_ONE, configIntent, 0);
    remoteViews.setOnClickPendingIntent(R.id.configure_text, configPendingIntent);
  }

  appWidgetManager.updateAppWidget(widget_id, remoteViews);
}

在其他部分，我推出了配置活动，并试图将小部件ID传递给它。然而，包始终为null：

In the else section, I'm launching a configuration activity and trying to pass the widget id to it. However, the bundle is always null:

Bundle extras = getIntent().getExtras();

if (extras != null) {
  int widget_id = extras.getInt("widget_id");
}

我怎样才能获得小部件ID的推出活动？

How can I get the widget id to the launched activity?

推荐答案

的问题是，Android为与PendingIntents缓存。解决的办法是增加，导致其以更新缓存的PendingIntent，在FLAG_UPDATE_CURRENT标志

The issue was that android does caching with PendingIntents. The solution was to add the FLAG_UPDATE_CURRENT flag which causes it to update the cached PendingIntent.

PendingIntent configPendingIntent = PendingIntent.getActivity(context, REQUEST_CODE_ONE, configIntent, PendingIntent.FLAG_UPDATE_CURRENT);
