Put this code here

}

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();
}
});

Listview doesn't appear at Fragment after second compile

Listview doesn't appear at Fragment after second compile.
The button at fragment works, so the problem is with listview and adapter, but I can't understand where the problem is.
Even if I delete the program and reinstall, it doesn't help. Only if move some other place method updatepost it can work once.
Hope for advice! I'm just learning all this.

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
{
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));
h._backgroundItem.setActivated(p._selected);
h._editBtn.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
((MainActivity)_con).onEditClick(p._url);
}
});
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)
{
_data = data;
notifyDataSetChanged();
}
private static class Holder

public LinearLayout _backgroundItem;
public TextView _fName;
public TextView _lName;
public TextView _age;
public Button _editBtn;
}

3) update your mainactivity

4) custom image layout

android:orientation="vertical" >
<ImageView
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
e.printStackTrace();
}

Not able to send data to server on clicking button?

public class PubHer extends Fragment{
EditText eCont;
Spinner spinnerareas3, spinnerareas4;
Button publish, switchArea;
static Context con;
String ite, cont, sno=""+12;
private Context globalContext = null;
public int item1, item2;
public static void fun(Context c) {
con = c;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_pubher, container, false);
spinnerareas3 = (Spinner) rootView.findViewById(R.id.spinnerplan1);
// ListView list = (ListView) rootView.getl
spinnerareas4 = (Spinner) rootView.findViewById(R.id.spinnerplan2);
// spinnerareas3.setOnItemSelectedListener();
spinnerareas3.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
item1 = position;
ite = ""+parent.getSelectedItemPosition();
CharSequence charS = item1+"";
Toast.makeText(con ,charS , Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
spinnerareas4.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
item2 = position;
CharSequence charS = item2+"";
Toast.makeText(con ,charS , Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
publish = (Button) rootView.findViewById(R.id.bPublish);
publish.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
cont = eCont.getText().toString();
upload();
}
});
switchArea = (Button) rootView.findViewById(R.id.bJumper);
switchArea.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
updateDetail();
}
private void updateDetail() {
// TODO Auto-generated method stub
Intent i = new Intent("com.example.notifier.JumpList");
startActivity(i);
}
});
return rootView;
}
protected void upload() {
// TODO Auto-generated method stub
if(item2==0)
new Sync_upload_event_info(this.getActivity(), 0).execute(sno,ite,cont);
else if(item2==1)
new Sync_upload_adver_info(this.getActivity(),0).execute(sno,ite,cont);
else
new Sync_upload_emer_info(this.getActivity(),0).execute(sno,ite,cont);
}
}
And this is my one of the sync files to server
public class Sync_upload_event_info extends AsyncTask{
private Context context;
String sno, place_id, event_text;
public Sync_upload_event_info(Context context,int flag)
{
context=this.context;
int getorpost=flag;
}
protected void onPreExecute(){ }
#Override
protected String doInBackground(String... arg0)
{
try{
sno = (String)arg0[0];
place_id = (String)arg0[1];
event_text = (String)arg0[2];
String link = "http://notifiermmn.site50.net/upload_event_info.php?sno="+sno+"&place_id="+place_id+"&event_text="+event_text;
link=link.replaceAll(" ", "%20");
System.out.println("LINK:"+link);
//URL url = new URL(link);
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
//request.setURI(new URI(link));
HttpResponse response = client.execute(new HttpGet(link));
return "";
}
catch(Exception e)
{
return new String("Exception: " + e.getMessage());
}
}
protected void onPostExecute(String result){
}
}
as soon as I press the publish button and set the spinner 4 to event ie Sync_upload_event_info or other two My app gets crashed.
the logcat is also indicating to the publish button click handling but not able to resolve

I think you forget to create reference of eCont EditText like:
EditText eCont= (EditText)rootView.findViewById(R.id.cont);
Your app crashed it's bacause eCont is NULL in your publish button Click event.
