How to call onUpdate () in AppWidgetProvider?

Question

this is my code ...

String[] show = new String[2]; RemoteViews remoteViews; public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget"; public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget"; @Override public void onUpdate( Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds ) { show = getString(); remoteViews = new RemoteViews( context.getPackageName(), R.layout.widget ); remoteViews.setTextViewText( R.id.widget_title, show[0]); remoteViews.setTextViewText( R.id.widget_textview, show[1]); Intent configIntent = new Intent(context, SuitAuto.class); configIntent.setAction(ACTION_WIDGET_CONFIGURE); Intent active = new Intent(context, WordWidget.class); active.setAction(ACTION_WIDGET_RECEIVER); active.putExtra("msg", "Message for Button 1"); PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0); PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0); remoteViews.setOnClickPendingIntent(R.id.update, actionPendingIntent); remoteViews.setOnClickPendingIntent(R.id.Lilo, configPendingIntent); appWidgetManager.updateAppWidget(appWidgetIds, remoteViews ); } private String[] getString() { String[] hon = new String[2]; KamusWidget ad = new KamusWidget(null); ad.open(); hon = ad.getwordday(); ad.close(); return hon; } @Override public void onReceive(Context context, Intent intent) { // v1.5 fix that doesn't call onDelete Action final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { // check, if our Action was called if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) { String msg = "null"; try { msg = intent.getStringExtra("msg"); } catch (NullPointerException e) { Log.e("Error", "msg = null"); } Toast.makeText(context, msg, Toast.LENGTH_SHORT).show(); } else { // do nothing } super.onReceive(context, intent); } } } 

I just want to update widget_title and widget_textview when I click on R.id.update it needs to run the getString function to retrieve a string from another class so that a new string can be passed to the text box ...

any idea?

Answer 1

At the end of the onReceive function onReceive you can simply create a RemoteView and update the widget:

 ComponentName name = new ComponentName(context, WordWidget.class); int[] ids = appWidgetManager.getAppWidgetIds(name); if(ids != null && ids.length > 0){ RemoteView remoteViews = new RemoteViews( context.getPackageName(), R.layout.widget ); remoteViews.setTextViewText( R.id.widget_title, context.getString(R.id.new_widget_title)); remoteViews.setTextViewText( R.id.widget_textview, context.getString(R.id.new_widget_text)); Intent configIntent = new Intent(context, SuitAuto.class); configIntent.setAction(ACTION_WIDGET_CONFIGURE); Intent active = new Intent(context, WordWidget.class); active.setAction(ACTION_WIDGET_RECEIVER); active.putExtra("msg", "Message for Button 1"); PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0); PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0); remoteViews.setOnClickPendingIntent(R.id.update, actionPendingIntent); remoteViews.setOnClickPendingIntent(R.id.Lilo, configPendingIntent); appWidgetManager.updateAppWidget(ids, remoteViews ); } 

I believe that you will also need to set intentions: if you do not, the buttons will stop working after updating RemoteView.

I believe

 Intent active = new Intent(context, WordWidget.class); active.setAction(ACTION_WIDGET_RECEIVER); 

Must be

 Intent active = new Intent(ACTION_WIDGET_RECEIVER); 

Broadcast PendingIntents do not work if their intention was not created by a simple line. setAction () for some reason does not do the same.
