Question

Is there any way to make dialog like in EditTextPreference outside of PreferenceActivity?
Let’s say I want this dialog to appear on button click in my main Activity.

I’ve tried to build a Dialog with a custom layout but I don’t know how to make it exactly the same as in EditTextPreference.

Sure, basically all you need is an AlertDialog with an EditText as a child view.
Short example:

AlertDialog.Builder adb = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
adb.setTitle("My title");
adb.setView(input);
adb.setPositiveButton("Ok", new OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {
                String inputText = input.getText().toString();
                // Do something with the input here             
            }

        });
adb.setNegativeButton("Cancel", null);
adb.show();

All you do here is creating an EditText instance in code and set it as the dialogs content via setView(). Just make it final so you can access it from the anonymous OnClickListener in this example. Of course you can refactor that a bit, but I think it’s already pretty handy.

this is referencing a Context here. Since you are calling the dialog from an Activity (extends Context), you should be fine.
