Show ListView header even when ListView has no items

Since my ListView is in a ScrollView and there is a complex layout above the ListView I had to set that layout to be the header of the ListView. This made things work wonderfully, except one thing: When the ListView has no items, the header does not show up. This header is basically the base of the whole layout, the ListView includes only comments written by users.
I checked solutions like this and this and this and others but I still don't know what to do.
This is how I set the header for the ListView:
lv = (ListView) findViewById(R.id.bucket_profile_lv);
LayoutInflater inflater=getLayoutInflater();
header = inflater.inflate(R.layout.bucket_profile_header,null,false);
lv.addHeaderView(header);
When I am downloading the data for the header, it has nothing to do with the adapter of the ListView. I refer to them as
num_added = response.getString("NUM_ADDED");
tv_num_added.setText(String.valueOf(num_added));
where
tv_num_added = (TextView) header.findViewById(R.id.bucket_profile_bucket_no_added);
When I am downloading the comments, I put the result (username, photo, comment etc.) in arrays and link them to an adapter:
if (response.length() > 10) {
try {
jArray = new JSONArray(response);
for(int i=0;i<jArray.length();i++){
JSONArray innerJsonArray = jArray.getJSONArray(i);
for(int j=0;j<innerJsonArray.length();j++){
JSONObject jsonObject = innerJsonArray.getJSONObject(j);
arr_tips_id.add(jsonObject.getString("COMMENTID"));
arr_tips_userid.add(jsonObject.getString("ID"));
arr_tips_username.add(jsonObject.getString("USERNAME"));
arr_tips_userphoto.add(jsonObject.getString("PHOTO"));
arr_tips_fbuserid.add(jsonObject.getString("FB_USERID"));
arr_tips_imagetype.add(jsonObject.getString("IMAGE_TYPE"));
arr_tips_twuserid.add(jsonObject.getString("TW_USERID"));
arr_tips_twphoto.add(jsonObject.getString("TW_PHOTO"));
arr_tips_tips.add(jsonObject.getString("COMMENT"));
arr_tips_date.add(jsonObject.getString("TIMEDIFF"));
myadapter = new MyAdapter(BucketProfileActivity.this, arr_tips_id, arr_tips_userid, arr_tips_username, arr_tips_userphoto, arr_tips_fbuserid, arr_tips_imagetype, arr_tips_twuserid, arr_tips_twphoto, arr_tips_tips, arr_tips_date);
lv.setAdapter(myadapter);
lv.setVisibility(View.VISIBLE);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
/*Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss:SSS");
String strDate = sdf.format(c.getTime());
Toast.makeText(BucketProfileActivity.this, "3 -- " + strDate + "", Toast.LENGTH_LONG).show();*/
} else {
Toast.makeText(BucketProfileActivity.this, "No comments, how to show header?", Toast.LENGTH_SHORT).show();
lv.setVisibility(View.VISIBLE);
}
In my adapter I have overriden isEmpty() but it didn't help:
#Override
public boolean isEmpty() {
return false;
}
Please help.

Don't use addHeaderView. Instead make the header as a separate item
<LinearLayout
...
android:orientation="vertical">
<include layout="#layout/bucket_profile_header" />
<ListView
.....
/>
</LinearLayout>

Initialize your adapter once, for example when you inflate your views in onCreate() or onCreateView() and also set your adapter to your listview (after you added your headerView).
In your JSON iteration loop do something like this:
myadapter.addItem(arr_tips_date);
In your adapter you have to create this method, which adds your data item to its internal adapter collection and call notifyDataSetChanged().
Then it should work just fine.

Listview only filling with first item

I have a Listview that gets its contents from an async task, but only the first item is actually getting placed into the Listview.
My xml for the activity is:
<?xml version="1.0" encoding="utf-8"?>

The async task is:
public class PortfolioGetAllBeers extends AsyncTask

Dialog.setTitle("Loading");
Dialog.setCancelable(false);
Dialog.show();
}
protected void onPostExecute(String result){
//decode json here
try{

//acces listview
ListView lv = (ListView) ((Activity) c).findViewById(R.id.allYourBeersList);
//make array list for beer
final List<ShortBeerInfo> tasteList = new ArrayList<ShortBeerInfo>();
for(int i = 0; i < jsonArray.length(); i++) {
String beer = jsonArray.getJSONObject(i).getString("beer");
String rate = jsonArray.getJSONObject(i).getString("rate");
String beerID = jsonArray.getJSONObject(i).getString("id");
String breweryID = jsonArray.getJSONObject(i).getString("breweryID");
int count = i + 1;
beer = count + ". " + beer;
//create object

//add to arraylist
tasteList.add(tempTaste);
//add items to listview
ShortBeerInfoAdapter adapter1 = new ShortBeerInfoAdapter(c ,R.layout.brewer_stats_listview, tasteList);

//get beer details from id
Intent myIntent = new Intent(c, BeerPage2.class);

c.startActivity(myIntent);
}
});
}
}
catch(Exception e){
}

}
public String readJSONFeed(String URL) {

Why I am confused is because my json is coming back with more then one result:

I think you can't see the list properly because your ListVew is within a ScrollView. ListView itself is scrollable , so it doesn't show properly in a ScrollView , you can at most see a ListView with very small height that fits one or two elements. Try using your ListView outside of ScrollView to test whether your code is correct or not. Hope it helps.

The short answer is that your doing it wrong.
You should be asynchronously loading the data into a sqlite db table and using a Loader with a cursor adapter.
Also, even using the code you have (and its hard to read from my phone here) it looks like your only adding one element to the list before you add the list adapter to the list view, which would be why you are only seeing a single item.
Another thing that may be causing you trouble is that you're asynchronously loading the data into a list view that has been created but you don't seem signal that the adapter has new data as the task finishes.

Move your code for the adapter so that it is outside and below your for loop. You are creating a new adapter for every iteration and it is probably running really slow because of it. Also you are setting your onitemclicklistener for every iteration too. It only needs to be done one time.
Do that and then see what happens. Also put a breakpoint after the for loop and see how many items are in your tasteList. If there is more than one then your adapter is most likely the problem.
If you can post your code for your adapter.
I guess my answer is that you probably aren't returning back more than one item. Since the adapter is posting data to the list it should be ok. Once you can debug the app and see how many items are returning then we can know for sure.

ArrayAdapter in Android Project [duplicate]

Here is my list view:
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_margin="5dip"
android:layout_weight="30">
</ListView>
And here is how I pass each product seperately.
<?xml version="1.0" encoding="utf-8"?>
<!-- Single List Item Design -->
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/label"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip"
android:textSize="16sp"
android:textStyle="bold" >
</TextView>
Now and according to the the aforementioned code I'm passing to each line just a simple string. However, I was wondering how could I pass three different Strings. The reason that I want to pass three different Strings is that I want them to be in the following format:
Quantity X
Number Price(this should be at the end of the line)

You have to derive from adapter, and provide properly filled views. Like here:
https://github.com/ko5tik/camerawatch/blob/master/src/de/pribluda/android/camerawatch/CameraAdapter.java
For better performance consider:
reusing views supplied to getView() method#
utilise viewHolder patern to save getViewById() resolution

How to set and get the id for the items in the spinner in Android

I have a problem like I had a Spinner containing the Names of all developers working in the Company.
I have used the ArrayAdapter with a Array having the names of all the developers which is fetched from the database.
The problem is that when I update the Name Of Developer field, I get Only the Name of the Developer which is not enough to update the data as their can be multiple developers with the same name in the Company.
So now I require the id of the developers to update it..
How to store that id of the developers with the Spinner so that I can achieve this.
For example, I want to do like is as that we do in HTML::
<select>
<option id="1">Developer1</option>
<option id="2">Developer2</option>
<option id="3">Developer2</option>
<option id="4">Developer2</option>
</select>
where the id attached would be the database id.
I want to imitate this in android.
This the code that I have used to store the names in the array::
String alldevelopers = null;
try
{
ArrayList<NameValuePair> postP = new ArrayList<NameValuePair>();
alldevelopers = CustomHttpClient.executeHttpPost("/fetchdevelopers.php", postP);
String respcl = alldevelopers.toString();
alldevelopersParser dev = new alldevelopersParser();
ow = dev.parseByDOM(respcl);
}
catch (Exception e) {
e.printStackTrace();
}
String developers[] = new String[ow.length]; //dev is a class object
for (int n = 0; n < ow.length; n++)
{
developers[n] = ow.developer[n][2];
}
This is the Spinner that would spin the array..
final Spinner devl = (Spinner) findViewById(R.id.towner);
devl.setOnItemSelectedListener(managetasks.this);
ArrayAdapter<String> b =
new ArrayAdapter<String>getApplicationContext(),
android.R.layout.simple_spinner_item,developers);
b.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
devl.setAdapter(b);

When you perform setOnItemSelectedListener on the spinner then you have method such as
public void onItemSelected(AdapterView<?> adapterView, View view,
int position, long id) {}
here you can findout the position of selected developer name of spinner and use this position to fetch data from array.

heres my android code
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
// Instantiate a JSON object from the request response
JSONObject obj = new JSONObject(json);
List<String> items = new ArrayList<String>();
Log.i("json", "getting json");
JSONArray jArray = obj.getJSONArray("news");
for (int i=0; i < jArray.length(); i++)
{ JSONObject oneObject = jArray.getJSONObject(i);
items.add(oneObject.getString("title"));
}
setListAdapter ( new ArrayAdapter<String>(this, R.layout.single_item, items));
ListView list = getListView();
list.setTextFilterEnabled(true);
list.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(),1000).show();
}
});
} catch(Exception e){
// In your production code handle any errors and catch the individual exceptions
e.printStackTrace();
}
}
I have tried logging it at LogCat gets the result no value for news.
so my question is why?

First of your json response is invalid.
You can test your JSON response at JSONLint.com
Second, first you have to fetch "data" object as a JSONObject and then you can able to fetch "news" JSONArray.
JSONObject objData = obj.getJSONObject("data");
JSONArray jArray = objData.getJSONArray("news");
