Question

I have a ListAdapter in my android application… I am trying to add a ratingBar to each item in the list with its value set to a value that is contained in [TAG_RATING]. The problem is that the list is showing and the only ratingBar is being stuck at the very bottom of the list and is rather large.

Please see the below code:

   ListAdapter adapter = new SimpleAdapter(
                        AllProductsActivity.this, productList,
                        R.layout.list_item, new String[] { TAG_BID,
                                TAG_NAME,
                                TAG_RATING},
                        new int[] { R.id.pid, R.id.name, R.id.ratingBar});
                    ((SimpleAdapter) adapter).setViewBinder(new MyBinder());
                // updating listview
                setListAdapter(adapter);

then the ViewBinder class looks like this:

   class MyBinder implements ViewBinder{
    public boolean setViewValue(View view, Object data, String textRepresentation) {
        if(view.getId() == R.id.ratingBar){
            String stringval = (String) data;
            float ratingValue = Float.parseFloat(stringval);
            RatingBar ratingBar = (RatingBar) view;
            ratingBar.setRating(ratingValue);
            return true;
        }
        return false;
    }
}

And the list item xml file looks like this:

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >


<TextView
    android:id="@+id/pid"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:visibility="gone" />

<!-- Name Label -->
<TextView
    android:id="@+id/name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingTop="6dip"
    android:paddingLeft="6dip"
    android:textSize="17dip"
    android:textStyle="bold" />

  <RatingBar
    android:id="@+id/rating"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="6dip"
    android:stepSize="0.25"
    android:numStars="5"
    />

Answer 1

The RatingBar widget should be placed in the list row layout that you use in the adapter, R.layout.list_item. Right now, you just placed a RatingBar widget below the ListView in the main layout.
