Firstly i used it this way after trying viewholder and didn't work so i
wanted every layout for both send and receive to be separated so when flag
true and i'm receiving it should update only current item with the name and
FB profile picture of sender and keep previous rows without updating ,here
is all the code
public class MarkChat extends Activity {
// private ArrayList<Chat> chatList = new ArrayList<Chat>();
private ArrayList<String> messages = new ArrayList<String>();
static ArrayList<String> Name = new ArrayList<String>();
EditText mSendText;
Context context;
ConversationListAdapter adapter;
private static Handler mHandler = new Handler();
ListView list;
String friendJid;
Message message;
static String Messname;
static String messagfrom;
String friendName;
Bitmap img;
String MYNamen = "Me";
int num=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.bubbles);
list = (ListView) findViewById(R.id.chatlist);
// /getting buddy info
Bundle b = getIntent().getExtras();
friendJid = b.getString("username");
friendName = b.getString("BuddyNAME");
Log.d("friendName", "" + friendName);
if (getIntent().hasExtra("byteArray")) {
img = BitmapFactory.decodeByteArray(
getIntent().getByteArrayExtra("byteArray"), 0, getIntent()
.getByteArrayExtra("byteArray").length);
}
// some where in code
Name.add(friendName);
Name.add(MYNamen);
adapter = new ConversationListAdapter(getApplicationContext(),
num, messages);
mSendText = (EditText) findViewById(R.id.chat_input_text);
// when I send/receive msg. -----------------START-------------
if (Main.conn != null) {
// Add a packet listener to get messages sent to us
PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
Main.conn.addPacketListener(new PacketListener() {
public void processPacket(Packet p) {
if (message.getBody() != null) {
adapter.flag = true;
messages.add(message.getBody());
Log.d("AsmackRecieve", "" + adapter.flag);
// Add the incoming message to the list view
mHandler.post(new Runnable() {
public void run() {
list.setAdapter(adapter);
//adapter.notifyDataSetChanged();
}
});
}
}
}, filter);
adapter.flag = false;
}
// Set a listener to send a chat text message
Button send = (Button) this.findViewById(R.id.chat_send_button);
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String text = mSendText.getText().toString();
adapter.flag = false;
Log.i("XMPPClient", "Sending text [" + text + "] ");
message = new Message(friendJid, Message.Type.chat);
message.setBody(text);
Main.conn.sendPacket(message);
messages.add(text);
list.setAdapter(adapter);
//adapter.notifyDataSetChanged();
}
});
// when I send/receive msg. ---------------END---------------
}
}
class ConversationListAdapter extends ArrayAdapter<String> {
Context con;
LayoutInflater mInflater;
ArrayList<String> groups;
ArrayList<String> groupsMessage;
boolean flag = false;
TextView title, titleOdd, body, bodyOdd;
public ConversationListAdapter(Context context, int textViewResourceId,
ArrayList<String> objects) {
super(context, textViewResourceId, objects);
this.con = context;
mInflater = LayoutInflater.from(context);
this.groupsMessage=objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder h;
View v = null;
if (flag) {
if (convertView == null) {
// //for incoming
h = new ViewHolder();
v = mInflater.inflate(R.layout.evenbubble, null);

}
Log.d("FLAG", "" + flag);

titleOdd.setText(MarkChat.Name.get(1));
}
return v;
}
}
