Can't make toast from stream in AppWidgetProvider class
I have an application that can load some data from a web service (in stream to onReceive()
) by clicking on it. The widget's GUI is then refreshed to updateWidget(...)
(= re-drawn).
I want to make a toast when it's done. I tried really hard to make a toast at the end updateWidget(...)
, passing the context from stream to toast, but it didn't work. The problem seems to be the context. Since my class inherits from AppWidgetProvider
and NOT from Activity, I CANNOT use things like getApplicationContext()
. I guess I just need to get the right context for the toast, but I have no idea how.
Here's the relevant code:
@Override
public void onReceive(Context context, Intent intent)
{
// Name of the action of the intent
final String action = intent.getAction();
// This way the context and the intent can be used in the thread
final Context ctx = context;
final Intent i = intent;
if (action.equals(COUNT_DOWN) == true || action.equals(COUNT_UP) == true)
{
// Show toast to inform the user that this feature is only available in the full version
Toast.makeText(context, R.string.no_groupchange, Toast.LENGTH_SHORT).show();
}
// Update current group
else if (action.equals(UPDATE_WIDGET))
{
// Check for internet connection
if (isOnline(context) == true)
{
// Show toast to inform the user that refreshing the data has started
Toast.makeText(context, R.string.refreshing, Toast.LENGTH_SHORT).show();
// This way the complete internet communication is independent from the GUI
// Also works at low speed internet connection
Thread myThread = new Thread(new Runnable()
{
@Override
public void run()
{
// TODO Auto-generated method stub
int currentGroupOrderID = soapManager.getCurrentGroupOrderID(LEAGUE_SC);
theGroup = soapManager.getGroup(currentGroupOrderID, LEAGUE_SC, SAISON);
nextMatch = soapManager.getNextMatch(LEAGUE_SC);
updateWidget(ctx, i);
}
});
myThread.start();
}
else
{
Toast.makeText(context, R.string.no_internet, Toast.LENGTH_SHORT).show();
}
}
super.onReceive(context, intent);
}
public void updateWidget(Context context, Intent intent)
{
// Creating remoteViews for updating the widget
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout_simple);
// Fill the textViews with text
setTextViewsFromTheGroup(remoteViews);
setNextMatchTextView(remoteViews);
// Update the widget
ComponentName widget = new ComponentName(context, SoccerWidgetProvider.class);
AppWidgetManager awm = AppWidgetManager.getInstance(context);
awm.updateAppWidget(widget, remoteViews);
// This way the widget doesn't stop reacting after some time
final int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID)
{
attachIntents(context, remoteViews, appWidgetId);
}
// HERE I WANT TO MAKE A TOAST!!!
