How to add Listview as footer in listview in android?

I have Mainactivity which contain listview with some item and I want to add another listview in that listview as footer.How can I add this

Its not recommended to add a ListView as a footer of another ListView. You might consider making a list of objects containing both list and pass the list to your Adapter.
So if you merge two lists in a common format, you need to be tricky for the layout selection for each item in your list. Let me show you an example of a common class.
public class CommonClass {
// Set null values initially.
private ClassA mFirstListClass = null;
private ClassB mSecondListClass = null;
}
Now take an ArrayList of this object to pass it to your Adapter. In your bindView check if the item is a ClassA object or ClassB object (as you can easily determine them by checking which object is null) and then set proper action.
I think for these kinds of problems RecyclerView is better. Its very simple to implement and you can find the implementation document here.

// Create a List from String Array elements
final List<String> tests = new ArrayList<String>(Arrays.asList(test));
// Create an ArrayAdapter from List
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, tests);
// DataBind ListView with items from ArrayAdapter
lv.setAdapter(arrayAdapter);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Add new Items to List
tests.add("abc");
tests.add("def");
/*
notifyDataSetChanged ()
Notifies the attached observers that the underlying
data has been changed and any View reflecting the
data set should refresh itself.
*/
arrayAdapter.notifyDataSetChanged();
}
});

Programatically replace String Array in a ListView Array Adapter

I have a ListView that i have populated with a string array: {"1","2","3"} using an Array Adapter.
(ListView) ListOptions = (ListView)findViewById(R.id.ListOptions);
String[] exampleString = new String[]{"1","2","3"};
ListAdapter adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,exampleString);
ListOptions.setAdapter(adapter);
Later on, i want to be able to change exampleString to exampleString2:
{"4","5","6"}
and have the ListView update with exampleString2 displayed as the list options.
is there something i can do along the lines of:
adapter.ChangeStringArray(exampleString2);
ListView.setAdapter(adapter);
I want to avoid having to create a new adapter each time I change the String array that is populating the list items.

ArrayAdapter has methods for managing the backing data array.
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, new ArrayList<String>());
adapter.addAll(exampleString);
adapter.clear();
adapter.addAll(exampleString2);
adapter.notifyDataSetChanged();

Constructor cannot be resolved

I am trying to create an array adapter to populate my list view.
Below is the code I have however the Array Adapter gets the error "Cannot resolve constructor".
Can anybody please help me with why this might be happening?
Thanks.
private void populateListView(){
//Create list of items'
String[] myItems = {"Blue", "red", "green", "purple"};
//Build adapter
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.deal_items, myItems);
//Configure the list view
ListView list = (ListView) findViewById(R.id.listViewMain);
list.setAdapter(adapter);
}

The first parameter to the ArrayAdapter constructor needs to be a Context. You appear to have implemented this method in a Fragment, which is not a Context. If so, then replace this in the ArrayAdapter constructor with getActivity().

Adding data at the specific position of Listview in android

I have a listview and I have to add two more element in listview. I have to add notifyDataSetChanged() . but not sure how to do it.
listView = (ListView) findViewById(R.id.my_listview);
myListAdapter = new MyListAdapter (this, sourceList);
listView.setAdapter(myListAdapter);
myListAdapter.notifyDataSetChanged();
sourceList is the List .
I need to add 2 items at the end of the Listview. Thanks.

Just add your desired data to the adapter. For example:
myListAdapter.add(obj1);
The newly added data will be attached at the end of your ListView.
Remember: when injecting data directly into an Adapter, you don't need to call its notifyDataSetChanged method.
If you modify your sourceList object, in that case its necessary to call notifyDataSetChanged method in order for the Adapter to refresh its contents.

Check out this Dummy Example to add the adapter to the List.
Read the Comment
ListView lstViewtodo; //Your ListView
List<NoteModel> list_note_model = new ArrayList<NoteModel>(); // for Adding the Array of your Model
NoteModel noteModel = new NoteModel(txttitle, jsonArray, obj.getUid(), txtColorType, false); //Your Model
list_note_model.add(0, noteModel); //Adding the value to array
lstViewtodo.setAdapter(list); //finally adding the content to list
To Add the Content Dynamically...
NoteListAdapter list = new NoteListAdapter( NoteMainActivity.this , R.layout.todo_adapter_view , list_note_model); //Your class extending the ArrayAdapter<NoteModel>
NoteModel noteModel = new NoteModel(txttitle, jsonArray, obj.getUid(), txtColorType, false);'
list_note_model.add(0, noteModel);
list.notifyDataSetChanged();

Error when adding a List to custom adapter - Android

I have a class that takes 4 parameters for a List. The class is called Item. I created a List variables that is an ArrayList . I then create a new ListAdapter. I set this adapter to the main ListView. I then add 10 inputs into the the ArrayList. This all works but when I try to add the ArrayList Items to the ListAdapter is gives me an error saying to add a Cast to the method.
Here is the code that I am talking about
final List <Item> tempList = new ArrayList <Item>();
mainListViewListAdapter = new ListAdapter(MainActivity.this, R.layout.main_list_item_layout, tempList);
// set mainListAdapter
mainListView.setAdapter(mainListViewListAdapter);
for (int x = 0; x < 10;x++){
tempList.add (new Item ("Example1","Example2","Example3","Example4"));
}
***HERE IS WHERE I GET THE ERROR AT addAll();***
mainListViewListAdapter.addAll(tempList);
mainListViewListAdapter is set to ListAdapter, and mainListView is set to ListView.
Why would I add a cast to mainListViewListAdapter? I have run this code on another project and I didn't have to use a cast.

Need destroy adapter - after using and configure each time use - new StringArray of Values for Adapter and new Adapter.
Use about this constructionale:
String[] values1 = new String[] { "Sunny", "Sealand", "Lengord" };
makeListItem(values1);
public void makeListItem(String[] addValues){
MySimpleArrayAdapter lvAdapter1 = new MySimpleArrayAdapter(this, addValues);
ListView1.setAdapter(lvAdapter1); lvAdapter1 = null; }
