Android appwidget turns other widget into the widget added & second widget wont work?

Question

I am making an android app that has 2 widgets. I have 1 widget set up and working, and the second widget is recognized in the widget list & loads correctly, but:

If I already have widget 1 on the screen when I add widget 2, both widgets change to widget 2. If I have a widget 2 and a widget 1, and add a widget 2, they all change to widget 2. The same happens if I add widget 1 - they all change to widget 1.

Also, nothing happens when widget 2 is clicked, even though I have used pretty much the same code from widget 1.

Below are the relevant files:

Can ANYONE tell me what the problem is? I am doing my nut in trying to figure it out :(

Answer 1

You havent made use of the onUpdate param int[] appWidgetIds.

You should loop through this, and apply any code to each one. At the moment you are not telling it which widget to update. Nor do you try and update more than the one widget.

Example below, note the loop on N. And the sub method also uses the id of the widget, which is passed from the loop on onUpdate.

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        Log.d(LOG_TAG, "Updating Example Widgets.");

        // Perform this loop procedure for each App Widget that belongs to this
        // provider
        for (int i = 0; i < N; i++) {
            int appWidgetId = appWidgetIds[i];

            // Create an Intent to launch ExampleActivity
            Intent intent = new Intent(context, WidgetExampleActivity.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            // Get the layout for the App Widget and attach an on-click listener
            // to the button
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget1);
            views.setOnClickPendingIntent(R.id.button, pendingIntent);
            // Tell the AppWidgetManager to perform an update on the current app
            // widget
            appWidgetManager.updateAppWidget(appWidgetId, views);


            // Update The clock label using a shared method
            updateAppWidget(context, appWidgetManager, appWidgetId);
        }
    }

    public static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
        String currentTime =  df.format(new Date());

        RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.widget1);
        updateViews.setTextViewText(R.id.widget1label, currentTime);
        appWidgetManager.updateAppWidget(appWidgetId, updateViews);
    }
