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
class CartAdapter extends BaseAdapter {

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
{
h = (Holder) convertView.getTag();
}
final Person p = getItem(position);
h._fName.setText(p._fName);
h._lName.setText(p._lName);
h._age.setText(String.valueOf(p._age));

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/image"/>
</LinearLayout>
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);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block

How to set listview row clickable only one time in android?

Explanation:
I have a listview in my fragment. When I click one of the row of the listview it goes to another activity.In listview,I got the data from the adapter.
Inside the adapter view,I set the setOnClick().
Problem is when I click one of the row multiple time it is opening multiple activity.I want to restrict only one time click on the particular row over the listview item.
Here is my fragment where I get the listview and set the adapter-
public class HomeFragment extends Fragment{
public HomeFragment() {
}
public static String key_updated = "updated", key_description = "description", key_title = "title", key_link = "link", key_url = "url", key_name = "name", key_description_text = "description_text";

This adapter set the listrow item into listview.
In ScheduleAdapter.java i set the onclick() on the convertView in which i called a GetValue class which is only implement a Asynctask to get the data and called and intent then it goes to an activity.
Means HomeFragment->ScheduleAdapter->GetValue->Scorecard
Here,
HomeFragment is fragment which have listview
ScheduleAdpter is an adapter which set data to listview which reside in homefragment
GetValue is class which implement some important task and it passed an intent and goes to an activity(It's work as a background)
ScoreCard is my activity which called after click on the row of the listview which reside in HomeFragment.
Please, help me to solve out this problem.

You can use a flag in Listview click - isListClicked, and set flag value as false in onPostexecute method of Aysnc task class -GetValue
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!isListClicked){
match_key = arr_matchKey.get(position);
MainActivity activity = (MainActivity) context;
GetValue gv = new GetValue(context);
gv.setFullUrl(match_key);
gv.setAccessToken(activity.getMyData());
gv.execute();
isListClicked = true;
}
}
});

If you want to prevent multiple activities being opened when the user spams with touches, add into your onClick event the removal of that onClickListener so that the listener won't exist after the first press.

Easy way is you can create a model class of your json object with those field you taken in holder class. And add one more boolean field isClickable with by default with true value.Now when user press a row for the first time you can set your model class field isClickable to false. Now second time when user press a row,you will get a position of row and you can check for isClickable. it will return false this time.
Model Class :
public class CountryInfoModel {
//other fields to parse json object
private boolean isClickable; //<- add one more extra field
public boolean isClickable() {
return isClickable;
}
public void setIsClickable(boolean isClickable) {
this.isClickable = isClickable;
}
}
listview click perform :
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//country_list is your list of model class List<CountryInfo>
if(country_list.get(position).isClickable())
{
//Perform your logic
country_list.get(position).setIsClickable(false);
}else{
//Do nothing : 2nd time click
}
}
});

Try creating your custom click listener for your listview and use it. In this way
public abstract class OnListItemClickListener implements OnItemClickListener {
private static final long MIN_CLICK_INTERVAL=600;
private long mLastClickTime;
public abstract void onListItemSingleClick(View parent, View view, int position, long id);
public OnListItemClickListener() {
// TODO Auto-generated constructor stub
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
long currentClickTime=SystemClock.uptimeMillis();
long elapsedTime=currentClickTime-mLastClickTime;
mLastClickTime=currentClickTime;
if(elapsedTime<=MIN_CLICK_INTERVAL)
return;
onListItemSingleClick(parent, view, position, id);
}
}

Custom adapter and click on item in ListView

No when I click on holder.expandIcon in first item, expand layout show in last item of list. How can I create list with my item and properly working click on image in every item?

You are expanding the last item in the list because that was the last view retrieved by getView. The way the code is written now, there is only one isExpand value.
So you need to (a) add isExpand on the ViewHolder, and (b) use the ViewHolder attached to the View that was passed in the event handler. Like this:
holder.expandIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ViewHolder vh = (ViewHolder)v.getTag();
if(vh.isExpand){
vh.actualOffersExpandLayout.setVisibility(View.INVISIBLE);
vh.isExpand = false;
}else{
vh.actualOffersExpandLayout.setVisibility(View.VISIBLE);
vh.isExpand = true;
}
}
});

First remove btnList, btnScan from your MainActivity class.
In your EfficientAdapter class add object Context Context
Change your contructor:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
to:
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
this.context=context;
}
In your ViewHolder class you need to add Button btnList.
Then in getview method find its view using holder.btnList
Then use:
holder.btnList.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent next=new Intent(context, SeviceDetails.class);
context.startActivity(next);
}
});
in your getview method before return convertView.

try this..
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_layout_ip_addtional_users, null);
}
//Handle TextView and display string from your list
TextView listItemText2 = (TextView)view.findViewById(R.id.list_item_string_name);
listItemText2.setText(list.get(position));
ImageButton button8 = (ImageButton) view.findViewById(R.id.ip_additional_user_edit);
button8.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, IPAdditionalUsersEdit.class);
context.startActivity(intent);
}
});
return view;
}
