listview is working properly
i just inflate cardview in listview.
when using this code image cannot displaying. only dispaly last image in list view
params.height = totalHeight
+ (myListView.getDividerHeight() * (myListAdapter
.getCount() - 1));
my problem is: In listview only displaying last image
check this image:

Try adding your ImageView to Holder class and use like viewholder.img.setImageBitmap(new LoadImage().execute(urll)) and change the return type to Bitmap

Use BaseAdapter instead of ArrayAdapter. Load and show image with UIL, Picasso or other image loader library.
public class ImageAdapter extends BaseAdapter {
private List<ImageBean> list;
private ArrayList<ImageBean> arraylist;
private LayoutInflater inflater;
public ImageAdapter(Context context, List<ImageBean> list) {
this.list = list;
inflater = LayoutInflater.from(context);
this.arraylist = new ArrayList<>();
}
#Override
public int getCount() {
return list.size();
}
#Override
public ImageBean getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.recycler_view_item, parent, false);
holder.ivImage = (ImageView) convertView.findViewById(R.id.ivImage);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// Loading image with UIL example
ImageLoader.getInstance().displayImage(getItem(position).getUrl(), holder.ivImage, ImageUtils.UIL_USER_AVATAR_DISPLAY_OPTIONS);
return convertView;
}
private class ViewHolder {
public ImageView ivImage;

ArrayList Index out of bounds exception in Custom Adapter with QuickReturn

How can i solve this ?

public int getCount() {
Log.i("tago" , "getCount ="+(channelbaba.size()+1));
return (channelbaba.size()+1);
}
try returing kanal.size()
or try removing +1 if the size of kanal and channelbaba are same

You shouldn't call in doInBackground() any method that updates the list.You should collect everything in doInBackground, return it as a result and then update the list in onPostExecute.
because onPostExecute and onProgressUpdate are executed in the UI thread, while doInBackground is executed in a different Thread.

Don't recreate your adapter each time doInBackground is call
mAdapter = new MyCustomAdapter(getActivity(), newsList);
listView.setAdapter(mAdapter);
Create it once and for all somewhere relevant.
mAdapter = new MyCustomAdapter(getActivity(), new ArrayList<HashMap<String, String>>());
listView.setAdapter(mAdapter);
And then return the List in doInBackground
return newsList;
And change onPostExecute like this, to integrate results in the adapter. onPostExecute runs in UI thread and has been designed to handle that kind of operation, like updating an adapter.
#Override
protected void onPostExecute(List<HashMap<String, String>> result)
{
// Assuming here MyCustomAdapter is an ArrayAdapter
mAdapter.clear();
mAdapter.addAll(result);
mAdapter.notifyDataSetChanged();
// [...]
}
The AsyncTask would look like this :
private class GetList_refresh extends AsyncTask<String, String, List<HashMap<String, String>>>

My guess is because you call setAdapter everytime you pull to refresh, in onPostExecute :
mAdapter = new MyCustomAdapter(getActivity(), newsList);
mAdapter.notifyDataSetChanged();
refreshable_listView.setAdapter(mAdapter);
refreshable_listView.onRefreshComplete();
Try to move :
mAdapter = new MyCustomAdapter(getActivity(), newsList);
refreshable_listView.setAdapter(mAdapter);
To your onCreateView because you only need to initialize and set the adapter once.
You just need to call those in your onPostExecute, because you called newsList.add in the onBackground :
mAdapter.notifyDataSetChanged();
refreshable_listView.onRefreshComplete();
The above's code will only change the data on your ListView, without re-initializing anything.

How to make a chat app like Facebook?

I'm working on a chat app. I want to create a cool design for my listview. My code is working but I want to add some design similar to the design of Facebook, but I have a problem.
I can't do this: i.e one user has an ID=52 and the other has=5293. If the user has Id=52, the textarea gravity in the left and the other in the right, and here my code it doesn't see my if statement every time print the else statement I don't know why really I put my ID in an array but really this is the same result.
public void LoadMessage() {
// TODO Auto-generated method stub
DatabseHandler d = new DatabseHandler(EchangingMessage.this);
String me = d.getData();
TextView you_id = (TextView) findViewById(R.id.you_id);
String you = you_id.getText().toString().trim();
Log.i("ID :", me + " : " + you);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("me", me));
params.add(new BasicNameValuePair("you", you));
JSONObject json = jParser.makeHttpRequest(url_daftar_rs, "POST",
params);
try {
int success = json.getInt(TAG_SUCCESS);
Log.i("success :", "" + success);
if (success == 1) {
daftar_rs = json.getJSONArray(TAG_DAFTAR_RS);
for (int i = 0; i < daftar_rs.length(); i++) {
JSONObject c = daftar_rs.getJSONObject(i);
String id_rs = c.getString(TAG_ID_RS);
String nama_rs = c.getString(TAG_NAMA_RS);
String link_image_rs = "http://10.0.2.2/www/Android_Login_Secure/Images/upload/big/"
+ c.getString(TAG_LINK_IMAGE_RS);
String message_rs = c.getString(TAG_MESSAGE_RS);
String time_rs = c.getString(TAG_TIME_RS);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_ID_RS, id_rs);
map.put(TAG_NAMA_RS, nama_rs);
map.put(TAG_LINK_IMAGE_RS, link_image_rs);
map.put(TAG_MESSAGE_RS, message_rs);
map.put(TAG_TIME_RS, time_rs);
DaftarRS.add(map);
}
} else {
finish();
}
} catch (Exception e) {
Log.e("Error", "COnnection:" + e.toString());
}

public void run() {
// updating listview

.findViewById(R.id.imageSender);

name_rs.setText(daftar_rs.get(MyMessages.TAG_NAMA_RS));

imageLoader.DisplayImage(
daftar_rs.get(MyMessages.TAG_LINK_IMAGE_RS), thumb_image);
}
return vi;
}
}

for this question we assume that my id =1 and you id =2
if (id==1) {
inflater.inflate(R.layout.item_list_right, parent, false);
else
{
inflater.inflate(R.layout.item_list_left, parent, false);
}
here you have to different layout one of them item_list_right and the other one is item_list_left
I solved this problem like this
