android - How to add two edit text fields in an alert dialog

I am trying to use an alert dialog to prompt for a username and a password in android. I have found this code here:

  if (token.equals("Not Found"))
    {
        LayoutInflater factory = LayoutInflater.from(this);            
        final View textEntryView = factory.inflate(R.layout.userpasslayout, null);

        AlertDialog.Builder alert = new AlertDialog.Builder(this); 

        alert.setTitle("Please Login to Fogbugz"); 
        alert.setMessage("Enter your email and password"); 
        // Set an EditText view to get user input  
        alert.setView(textEntryView); 
        AlertDialog loginPrompt = alert.create();

        final EditText input1 = (EditText) loginPrompt.findViewById(R.id.username);
        final EditText input2 = (EditText) loginPrompt.findViewById(R.id.password);

        alert.setPositiveButton("Login", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int whichButton) { 
            input1.getText().toString(); **THIS CRASHES THE APPLICATION**


        } 
        }); 

        alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, int whichButton) { 
            // Canceled. 
          } 
        }); 

        alert.show(); 

    }

EDIT: I was able to set up the proper layout, but receive an error when I try to access the text field. What is the problem here?

Check this code in alert box have edit textview when click OK it displays on screen using toast.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final AlertDialog.Builder alert = new AlertDialog.Builder(this);
    final EditText input = new EditText(this);
    alert.setView(input);
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            String value = input.getText().toString().trim();
            Toast.makeText(getApplicationContext(), value, 
                Toast.LENGTH_SHORT).show();
        }
    });

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            dialog.cancel();
        }
    });
    alert.show();               
}
