Android AppWidget: Add Custom Views to Widget Layout

Question

I want to show some list of TextView and EditView in my Widget.

I used the following code to generate list of TextView and EditView

public LinearLayout getMainBodyLayout(List<Item> data) {
        LinearLayout mainLL = new LinearLayout(context);
        mainLL.setOrientation(LinearLayout.VERTICAL);
        for (int i = 0; i < data.size(); i++) {
            Item ritem = data.get(i);
            LinearLayout item = new LinearLayout(context);
            TextView name = new TextView(context);
            EditText nos = new EditText(context);
            name.setText(ritem.getName());
            nos.setText(ritem.getNo());
            item.addView(name);
            item.addView(nos);
            mainLL.addView(item);

        }

        return mainLL;
    }

public void updateWidget(LinearLayout ll) {
        AppWidgetManager manager = AppWidgetManager.getInstance(context);
        ComponentName thisWidget = new ComponentName(context, MainWidget.class);
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.widget_my);
        remoteViews.setTextViewText(R.id.title, title);

        remoteViews.setTextViewText(R.id.widget_error, errorMsg);

// I ve to add ll to this remoteViews


        manager.updateAppWidget(thisWidget, remoteViews);
    }

I have to add the returned LinearLayout to my widget Linearlayout. Please provide me the best way to do this.

Do you want to make a list???? If so why dont you use a listview for that any issue with that ?? And listview will be faster than what you are doing right now. — BBdev, Jul 02 '13 at 09:53
@Sridhar in order to use ListViews in appwidgets take a look at http://developer.android.com/guide/topics/appwidgets/index.html#collections — Jose_GD, Dec 18 '13 at 20:55

Try to make Layout in XMl and set its value in Java file... and use method

          RemoteViews.setTextviewText(id,string);

try this method as i hv use it in my widget

        private class ABC extends TimerTask {
         RemoteViews remoteViews;
         AppWidgetManager appWidgetManager;
         ComponentName thisWidget;

         public ABC(Context context, final AppWidgetManager appWidgetManager) {
         this.appWidgetManager = appWidgetManager;


         remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
         thisWidget = new ComponentName(context, WidgetAnimate.class);
          }

         public void run() {

           String k= XMLfunctions.data1();   
           remoteViews.setTextViewText(R.id.tv12,k);
           appWidgetManager.updateAppWidget(thisWidget, remoteViews);

         }

I want to add custom views. I cannot use hard code no of subviews — Sridhar, Jul 02 '13 at 10:03

Thanks but I asked you about how to set adapter in AppWidgetProvider class. – Sridhar Jul 02 '13 at 11:04
If you will use ListView you can directly set adapter to listview. The listview is a widget provided by Android and seeing what you are doing is good to achieve by the list view. – BBdev Jul 02 '13 at 11:06
