Unable To Get All User In Asmack

I am developing chat app on Android base on asmack lib. I create 1 user and add 3 friend in buddy list. When I use roster to display buddy list. I can't get all user in buddy list,

Solution 1:

This is my buddies list

publicclassBuddiesListextendsActivity {
ListView list;
Roster roster;
static Buddy[] buddyList;

publicvoidonCreate(Bundle b) {
    super.onCreate(b);
    setContentView(R.layout.buddies);

    roster = AsmackTestingActivity.xmpp.getRoster();
    ArrayList<Buddy> buddies = newArrayList<Buddy>();
    Collection<RosterEntry> entries = roster.getEntries();
    buddyList = newBuddy[entries.size()]; 
    ProviderManager.getInstance().addIQProvider("vCard", "vcard-temp", newVCardProvider());
    Buddybud=null;
    VCardcard=null;
    inti=0;
    for (RosterEntry entry:entries) {
        bud = newBuddy();
        card = newVCard();
        try {
            card.load(AsmackTestingActivity.xmpp, entry.getUser());
        } catch (Exception e) {
            e.printStackTrace();
        }

        bud.jid = entry.getUser();
        bud.name = card.getField("FN");
        if (bud.name == null)
            bud.name = bud.jid;
        buddies.add(bud);
        byte[] img = card.getAvatar();
        if (img != null) {
            intlen= img.length;
            bud.img = BitmapFactory.decodeByteArray(img, 0, len);
        }
        buddyList[i++] = bud;
    }


    finalBuddyAdapteradapter=newBuddyAdapter(this, buddies);
    list = (ListView) findViewById(R.id.buddiesList);
    list.setAdapter(adapter);
    list.setOnItemClickListener(newOnItemClickListener() {
        publicvoidonItemClick(AdapterView<?> parent, View view, int position, long id) {
            Intentintent=newIntent(BuddiesList.this, AsmackChat.class);
            intent.putExtra("username", adapter.getItem(position).jid);
            startActivity(intent);
        }
    });
}

classBuddyAdapterextendsArrayAdapter<Buddy> {
    publicBuddyAdapter(Context context, ArrayList<Buddy> items) {
        super(context, R.id.buddyName, items);
    }

    @Overridepublic View getView(int position, View convertView, ViewGroup parentView) {
        Buddybud= getItem(position);
        ViewHolderholder=null;
        if (convertView == null) {
            convertView = getLayoutInflater().inflate(R.layout.buddy, null);

            holder = newViewHolder();
            holder.name = (TextView) convertView.findViewById(R.id.buddyName);
            holder.thumb = (ImageView) convertView.findViewById(R.id.buddyThumb);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.name.setText(bud.name);
        holder.thumb.setImageBitmap(bud.img);

        return convertView;
    }
}
classBuddy {
    String jid;
    String name;
    int status;
    Bitmap img;

}
classViewHolder {
    ImageView thumb;
    TextView name;
}

Layout buddies.xml:

<?xml version="1.0" encoding="utf-8"?><ListViewxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/buddiesList"android:layout_width="fill_parent"android:layout_height="fill_parent" ></ListView>

And layout buddy.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"android:padding="5dp"><ImageViewandroid:id="@+id/buddyThumb"android:layout_width="wrap_content"android:layout_height="wrap_content"android:paddingRight="5dp" /><TextViewandroid:id="@+id/buddyName"android:layout_toRightOf="@id/buddyThumb"android:layout_centerVertical="true"android:layout_width="wrap_content"android:layout_height="wrap_content"android:textColor="#FFFFFFFF"/></RelativeLayout>

Solution 2:

You are just having one buddy in your TextView because you are changing the text for each iteration.

Try something like textview.setText(textview.getText() + r.getName()); or add a new TextView for each buddy
