Answer 1

If you need to get the text from the EditText you have to do this:

LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);

and then, on the onclick() method you have to retrieve the text:

city.getText().toString();

but if you want to pass the string to the parent class you have to do an interface like this: http://developer.android.com/training/basics/fragments/communicating.html

Answer 2

You have to find editText id like this

price=(EditText)builder2.findViewById(R.id.price_search);

Answer 3

You should declaration your editText under the dialog method like,

LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);

After that, while doing onClick listener for postive button, you can get the content of editText using

city.getText().toString();

Hope this will help you.
