                    .setPositiveButton("OK",
                      new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int id) {
                         String emailname = etEmailName.getText().toString();
                         String emailadd = etEmailAddress.getText().toString();

                        if(emailname.equals("") || emailadd.equals("")){
                            Toast.makeText(Personal_Info.this, "enter name and email address", Toast.LENGTH_SHORT).show();
                        }else{
                            final String[] email =new String[]{emailname,emailadd};
                            setListAdapter(new ArrayAdapter<String>(getApplicationContext(), R.layout.row_item,email));
                            ListView list = getListView();
                             list.setTextFilterEnabled(true);

Seems like you never add any item to your list.

Adjust code like this:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.row_item,email);
adapter.add(email);
setListAdapter(adapter);

Did it work?

I see. You shouldn't create a new instance of your adapter inside the onclick method. create and set the adapter in the oncreate method and in your onclick just call .add(email) on your adapter – donfuxx Feb 14 '14 at 09:40
