android layout as emptyview of a listview programmatically made

I have an Activity extends ListActivity, where I had to create a ListView programmatically (no xml).
To set up an emptyView for it the only way that worked was the following code I found in another thread:
TextView emptyView = new TextView(this);
((ViewGroup) getListView().getParent()).addView(emptyView);
getListView().setEmptyView(emptyView);
now my goal is to do the same using a layout instead of a TextView, so I made an xml with its id and put it this way:
View emptyView = findViewById(R.id.empty_view_xml);
((ViewGroup) getListView().getParent()).addView(emptyView);
getListView().setEmptyView(emptyView);
but it doesn't seem to work..

Your problem:
Because your view (empty_view_xml) doesn't exist in the activity xml, so calling findViewById(R.id.empty_view_xml); will return a null value, and setting null as emptyView will do nothing.
Your current code: .setEmptyView(emptyView); is similar to .setEmptyView(null);.
To solve this:
You need to inflate your custom xml, then add it as EmptyView:
LayoutInflater inflater = LayoutInflater.from(YourActivity.this);
View emptyView = inflater.inflate(R.layout.empty_view_xml, null, false);
((ViewGroup) getListView().getParent()).addView(emptyView);
getListView().setEmptyView(emptyView);

inflate view returns the old inflated result

I try to inflate a layout multiple times to be inserted inside another layout. Here is the code:
View oldView = null;
for (ProfileServiceCategory.ProfileService service : profileServiceCategory.getServices()) {
View view = LayoutInflater.from(context)
.inflate(R.layout.profile_service_list_item, viewHolder.rootView);
if(oldView == view) {
Log.d("test", "Error");
}
oldView = view;
TextView serviceName = (TextView) view.findViewById(R.id.profile_services_name);
serviceName.setText(service.getServiceValue());
}
The problem that I'm facing is the view variable that is being returned by inflate method is always the first inflated view. To be clear I added a Log.d , if everything worked as expected it should have been never called but it does hit.
I checked the view hierarchy and I can conform that new views in fact has been added to rootView but the reference that I get is for older view.

One of my colleague suggested a workaround by adding the view manually to container. Here is the edited code:
LayoutInflater layoutInflater= LayoutInflater.from(context);
for (ProfileServiceCategory.ProfileService service : profileServiceCategory.getServices()) {
View view = layoutInflater.inflate(R.layout.profile_service_list_item, null);
TextView serviceName = (TextView) view.findViewById(R.id.profile_services_name);
serviceName.setText(service.getServiceValue());
viewHolder.rootView.addView(view);
}
When null is getting passed to inflate method as second argument a new view gets returned each time. The view can be inserted inside the container by addView method.
This is obviously a bug in android SDK.

LayoutInflater.from(context).inflate(R.layout.profile_service_list_item,
viewHolder.rootView);
is always returning the same inflater service. so i think you have to take copy of layoutInflater using cloneInContext
View view = LayoutInflater.from(this)
.cloneInContext(R.layout.layout_fullscreen_image, viewHolder.rootView);

Footerview not displaying always when scrolling the listview

I have a listview with an adapter. I want to add a footer and that this footer will be displayed when scrolling the listview. Right now with this code the footerview is displayed when the listview is finished. In the onCreate method of the list i have:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_listado_imagenes_subidas_main);
// load list application
listImagenes = (ListView)findViewById(R.id.lvImages);
LayoutInflater inflater = getLayoutInflater();
ViewGroup footer = (ViewGroup) inflater.inflate(R.layout.footer3buttons, listImagenes,
false);
listImagenes.addFooterView(footer, null, false);
// create new adapter
ImagenesAdapter adapter = new ImagenesAdapter(this, ListadoImagenes());
// set adapter to list view
listImagenes.setAdapter(adapter);
}
Could you please help me with this issue?
Thank you in advanced.

If i understood correctly what you wan't is a "sticky" footer the addFooterView method add a footer after the last view item, for a sticky footer you have to roll your own, or use an external library for it.

try with this one
View footerView = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
list.addFooterView(footerView);

How to add a view as ListView header

I have a View extending google MapView. And a ListView with items. What I need is to put MyMapView as a header to the list view. Help please what to do
Update: When I try to do this:
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ListView list = (ListView) findViewById(R.id.list);
View m = inflater.inflate(R.layout.map, list, false);
list.addHeaderView(m);
I got an error:
MapViews can only be created inside an instances of MapActivity
I think it's because I have removed my xml layout for map into different.xml from my activity

Try this
Create your ListViewHeader.xml first
and do this
ListView lv = getListView(); // Your listView
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.YourHeader, lv, false);
lv.addHeaderView(header, null, false);
take a look on Android: Adding static header to the top of a ListActivity

Try to call
ListView.addHeaderView (View v)
before you set adapter to this ListView

if you are using a custom adapter, in getView() method provide different view at position 0.
if(position==0)
{
//Provide header view
}
else
{
//provide normal row
}

You can do the following to add a view as ListView header in android.
ListView list = (ListView) findViewById(R.id.list);
LayoutInflater inflater = getLayoutInflater();
ViewGroup viewGroup= (ViewGroup)inflater.inflate(R.layout.YourLayoutFile,list, false);
list.addHeaderView(viewGroup, null, false);

Using ListView : How to add a header view?

I looke at the ListView API
and I saw the method:
addHeaderView(View v)
What I want to do is to have a layout above the list, is this possible ?
I tried doing something like :
EditText et=new EditText(this);
et.setLayoutParams(new Gallery.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
et.setInputType(InputType.TYPE_CLASS_TEXT);
addHeaderView(et); //makes app crash
I also tried
setContentView(R.layout.tryview);
but it also make the app crash.
Help is very much appreciated!
Edit : The code for this class is:
public class GroupsActivity extends ListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String your_array_contents[] = {"a","ab","c"};
setListAdapter(new ArrayAdapter<String>(this, R.layout.groups_layout, your_array_contents));
EditText et=new EditText(this);
et.setLayoutParams(new Gallery.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
et.setInputType(InputType.TYPE_CLASS_TEXT);
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
lv.setAdapter(new ArrayAdapter<String>(GroupsActivity.this,
android.R.layout.simple_list_item_multiple_choice, your_array_contents));
lv.addHeaderView(et); //makes app crash
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
// Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
//Toast.LENGTH_SHORT).show();
}
});
}
}

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.
And yes you can add header something like this way:
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

You simply can't use View as a Header of ListView.
Because the view which is being passed in has to be inflated.
Look at my answer at Android ListView addHeaderView() nullPointerException for predefined Views for more info.
EDIT:
Look at this tutorial Android ListView and ListActivity - Tutorial .
EDIT 2: This link is broken Android ListActivity with a header or footer

I found out that inflating the header view as:
inflater.inflate(R.layout.listheader, container, false);
being container the Fragment's ViewGroup, inflates the headerview with a LayoutParam that extends from FragmentLayout but ListView expect it to be a AbsListView.LayoutParams instead.
So, my problem was solved solved by inflating the header view passing the list as container:
ListView list = fragmentview.findViewById(R.id.listview);
View headerView = inflater.inflate(R.layout.listheader, list, false);
then
list.addHeaderView(headerView, null, false);
Kinda late answer but I hope this can help someone
