    <p>I'm using Android's custom adapters to create a list view for my application. I'm looking to show whether or not someone's in first, second or third place and also show unique badges for each person in the list. The code below works for ranking but it shows the same badges for each person. I can't quite seem to figure out why. If a person doesn't earn a badge, he or she should not see anything (when I set the array to null) each person's badges are set to null. I've been debugging this for a while and can't seem to figure out what's wrong. I imagine it's something simple. Thanks!</p> <pre><code> public class LeaderArrayAdapter extends ArrayAdapter&lt;UserStatus&gt; { private final String LOG_TAG = "LeaderArrayAdapter"; private final Context context; // UserStatus class: contains a text value - user name, an // integer value for the place (1st,2nd,3rd..) and an integer array for user // badges private final UserStatus[] values; // array of icons to represent a ribbon for each place (1st,2nd..) private static int[] placeIcons ={ R.drawable.first_ribbon1, R.drawable.ribbon_2, R.drawable.ribbon_3, R.drawable.ribbon_4, R.drawable.ribbon_5, R.drawable.ribbon_6, R.drawable.ribbon_7, R.drawable.ribbon_8, R.drawable.ribbon_9, R.drawable.ribbon_10, R.drawable.ribbon_11, R.drawable.ribbon_12, R.drawable.ribbon_13, R.drawable.ribbon_14, R.drawable.ribbon_15}; // This variable array contains the layout each badge should be placed - up to 9 // badges private static int[] badgeIconLayout = {R.id.action1, R.id.action2, R.id.action3, R.id.action4, R.id.action5, R.id.action6, R.id.action7, R.id.action8, R.id.action9}; // this array contains the specific R values that represent each badge in the drawables folder private static int[] badgeIcons = {R.drawable.aa, R.drawable.ab, R.drawable.ac, R.drawable.ad, R.drawable.ae,R.drawable.af, R.drawable.ag, R.drawable.ah, R.drawable.ai, R.drawable.aj, R.drawable.ak, R.drawable.al, R.drawable.am, R.drawable.an}; public LeaderArrayAdapter(Context context, UserStatus[] values) { super(context, R.layout.leaderboard_rowlayout, values); this.context = context; this.values = values; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); // Each row will contain a place icon, user name, user value, and user // badges.

    1. COThe code's a little difficult to follow. Comments would be helpful. Any reason you're setting the badge view 9 times? It will always be set to the last value anyway.

    2. COSorry, I added comments (and code for the ListView). 9 is the maximum number of badges that I will show. IE, I show up to 9 different badges. It actually sets to the first badge value.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
