    android:orientation="vertical" >

        <Button
            android:id="@+id/d"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"

        super.onCreate(savedInstanceState);
        setContentView(R.layout.addevent);
        myList = (ListView) findViewById(R.id.MyList);
        myList.setItemsCanFocus(true);
        myAdapter = new MyAdapter();
        myList.setAdapter(myAdapter);


        final LayoutInflater factory = getLayoutInflater();

        final View textEntryView = factory.inflate(R.layout.item, null);

        tvDisplayDate = (EditText)textEntryView.findViewById(R.id.editd);
        btnChangeDate=(Button)textEntryView.findViewById(R.id.d);

From insinde your MyAdapter class you can override the getView method (that's the one that produces the item renderers on demand).

After recycling / inflating the proper layout for the current item (say convertView), you can access all of its children using the findViewById method called on the convertView:

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        // initialize, inflate convertView from your layout if needed; 
        tvDisplayDate = (EditText)convertView.findViewById(R.id.editd);
        // populate convertView with the item's details
    }

Try this View view = LayoutInflater.from(getApplication()).inflate(R.layout.item, null);

How you can see, static from() method takes 1 argument(Context) and you obtains LayoutInflater from given Context, in your case it will be your Activity where you want to inflate View.

Hope it helps!
