Question

I am trying to create a homescreen widget using the 3.1 SDK. I followed the StackWidget tutorial. and changed the StackView to ListView.
I want to add an image and text to each row in my list, and these are loaded at runtime.

I use this code in my WidgetProvider.java class

public RemoteViews getViewAt(int position) {

    Bitmap bitmap = ((BitmapDrawable)mWidgetItems.get(position).getImage());

    RemoteViews image = new RemoteViews(mContext.getPackageName(), R.layout.widget_item);      
    image.setImageViewBitmap(R.id.widget_image, bitmap );

    RemoteViews text = new RemoteViews(mContext.getPackageName(), R.layout.widget_item); 
    text.setTextViewText(R.id.widget_text, mWidgetItems.get(position).getText());

    RemoteViews layout = new RemoteViews(mContext.getPackageName(), R.layout.widget_item);

    Bundle extras = new Bundle();
    extras.putInt(StackWidgetProvider.EXTRA_ITEM, position);
    Intent fillInIntent = new Intent();
    fillInIntent.putExtras(extras);

    layout.setOnClickFillInIntent(R.id.widget_item, fillInIntent);

    return layout;
}

All of this works correctly when I use StackView, but changing to ListView messes up everything. The result is this

Only one view can be returned. So, if I add the following code, this problem occurs, if I don’t add it, then the content of the list is empty.

layout.addView(R.id.widget_item, image);
layout.addView(R.id.widget_item, text);

How else do I add multple views to a widget?
Why does this work for StackView but not ListView?
and how do I rectify this?

Any help is greatly appreciated.

EDIT

widget_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_vertical">
<ImageView
    android:id="@+id/widget_image"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10dp"/>
<TextView
    android:id="@+id/widget_text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="20dp"
    android:layout_weight="1"
    android:textColor="#000000"/>       
</LinearLayout>

You rectify this by inflating the right layout from the outset. R.layout.widget_image should already have whatever stuff you have in R.layout.widget_image and R.layout.widget_item.

This will be:

• faster to execute (fewer instructions to achieve same visual end)
• less Java code
• less layout code (one layout file versus three)
• easier to maintain layout code (you can use the visual editor in Eclipse to maintain your list rows better)

And, as an extra bonus, it should work for any supported AdapterView-based app widget.
