        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);

any help please

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!

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
    }

@Akashkumar see the edited response with the full method signature: `convertView` is the second parameter of the `getView` method inside the `Adapter` implementation; – rekaszeru May 30 '16 at 09:53
I just spent an hour resolving this error. The only thing I missed was calling findViewById on convertView. Thanks for making me realize this! – waseefakhtar Nov 27 '17 at 00:24
