I have listview All the values are delete and update properly but only the last value is not delete in the listview.
Added a full fragment code. Take a look
For example
If I have three values in the listview If I delete 1 and 2 its removing and listview refresh properly but the last one is not refreshed in the listview

you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

Android:Receive Array of Objects and display in listView

Hello to all android folks over there!!
I want to get list of objects from web service and want to display them in list view.Now i am able to fetch those values and collected them in arraylist.But i am facing problem to display them in list view.below is my code.

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

how can i pass the image URL from activity to Alert Dialog box as a imageview?

Here is my CartRowHolder
class CartRowHolder {
ImageView icon;
TextView txtprice,txttitle,personalize;
TextView txtquantity;
ImageView imgdelete,imgedit,image;
public CartRowHolder(View v) {
icon=(ImageView)v.findViewById(R.id.imageicon);
txtprice=(TextView)v.findViewById(R.id.txtoprice);
txttitle=(TextView)v.findViewById(R.id.txtotitle);
txtquantity=(TextView)v.findViewById(R.id.txtoquantity);
personalize=(TextView)v.findViewById(R.id.txtpersonalize);
imgdelete=(ImageView)v.findViewById(R.id.imgdelete);
imgedit=(ImageView)v.findViewById(R.id.edit);
}
}
Now in the ListView a ImageView and Delete Button, Edit button is there So as i click on the Edit a Dialogbox is open and in the Dialogbox i want to pass the imageView.....and i have the ImageUrl

OK, you will need to following code:
1) add permission for internet in your manifest
<uses-permission android:name="android.permission.INTERNET" />
2) You will need to update your list adapter
private static final int MIN_RECORDS_NUMBER = 11;
private Context _con;
private List<Person> _data;
public PersonAdapter(Context context, List<Person> data)
{
_con = context;
_data = data;
}
#Override
public int getCount()
{
return _data.size();
}
#Override
public Person getItem(int position)
{
return _data.get(position);
}
#Override
public long getItemId(int position)
{
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
Holder h = null;
if (convertView == null)
{
h = new Holder();
convertView = LayoutInflater.from(_con).inflate(R.layout.item_layout, parent, false);
h._backgroundItem = (LinearLayout) convertView.findViewById(R.id.item_layout);
h._fName = (TextView) convertView.findViewById(R.id.f_name);
h._lName = (TextView) convertView.findViewById(R.id.l_name);
h._age = (TextView) convertView.findViewById(R.id.age);
h._editBtn = (Button) convertView.findViewById(R.id.edit_btn);
convertView.setTag(h);
}
else
{

}
final Person p = getItem(position);
h._fName.setText(p._fName);

h._editBtn.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{

}
});
convertView.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
Person p = getItem(position);
Intent i = new Intent(_con,SecondActivity.class);
i.putExtra("DATA", p._fName);
_con.startActivity(i);
}
});
return convertView;
}
public void setData(List<Person> data)

public LinearLayout _backgroundItem;
public TextView _fName;
public TextView _lName;
public TextView _age;

}

3) update your mainactivity

A bit of explanation:
there is an interface between the activity and the list adapter (IDialog)
as part of the data, each item(person) has a field URL, when the user is clicking on the button, the activity is "notified" by the interface and downloading the appropriate image and showing it in the dialog

After so any hour I find out the Soloution. Now In the Dialog-box i can again download the image.....
imageFileURL="url";
String imageFileURL=cartItemList.get(position).getImage();
try {
URL url = new URL(imageFileURL);
URLConnection conn = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection)conn;
httpConn.connect();
InputStream inputStream = httpConn.getInputStream();
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
inputStream.close();
image.setImageBitmap(bitmap);

I think you get error on below Line.
holder.ratingbar.setRating(Float.valueOf(rating));
This means the value inside "rating" is string, please check.

Setting Rating takes float value , in Case ur value is String :
holder.ratingbar.setRating(Float.parseFloat(rating));

use parseFloat()
holder.ratingbar.setRating(Float.parseFloat(rating));
inplace of
holder.ratingbar.setRating(Float.valueOf(rating));

I'm not sure where you are getting the value of rating. But it is attempting to parse that value of string to Float that is throwing your error.
String rating = recipelist.get(position).getRatings();
Also check that the string is not empty.
// if(rating!=null && rating.trim().length() > 0)
if(rating!=null && !rating.isEmpty() && rating.trim().length() > 0)
{
try{
holder.ratingbar.setRating(Float.valueOf(rating));
}
catch (NumberFormatException e){
// TO DO
}
}
Firstly examine the value of rating (log it) and if you are getting a float in there I suggest having a look at this answer:
float f = Float.valueOf("> 12.4N-m/kg.".replaceAll("[^\\d.]+|\\.(?!\\d)", ""));

response of this method should be float String rating = recipelist.get(position).getRatings();or to get it in String you have to convert it into String by using toString();thats why you are getting NumberFormatException

Android Universal Image Loader and GridView "Out of memory" on second launch

I have checked all the related posts so far, but did not managed to fix this "Out of memory on a 1843216-byte allocation" error my GridView activity generates.
Basically this activity displays the images from the phone's gallery in a GridView (as a multiple image picker), at first it loads everything just fine, at the second try I get the memory error and the GridView skips loading some of the image thumbnails.
I have disabled the memory caching by: ".cacheInMemory(false)", and using only disk caching with fixed ImageView width and height, but still got the memory error.
Could someone help me out? Thanks!

Try to do this with Picasso library instead of using image loader library. Hope this may helpful for you.
