Android imeOptions="actionDone" not working

I am trying to get a login screen for an Android app and so far this is my code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">


    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:orientation="vertical">

        <EditText
            android:id="@+id/username"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Username"
            android:inputType="text"
            android:singleLine="true"
            android:imeOptions="actionNext">

            <requestFocus />
        </EditText>

        <EditText
            android:id="@+id/password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Password"
            android:inputType="textPassword"
            android:singleLine="true"
            android:imeOptions="actionDone"  />

        <Button
            android:id="@+id/buttonLaunchTriage"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:text="@string/login" />
    </LinearLayout>



</RelativeLayout>

When I try to run it, the keyboard shows the right keys but when I try to press done after entering the password, nothing happens. I am using this to handle the button press:

private void setupLoginButton() {
    Button launchButton = (Button) findViewById(R.id.buttonLaunchTriage);
    launchButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            EditText username = (EditText) findViewById(R.id.patient_start_userName_value);
            EditText password = (EditText) findViewById(R.id.patient_start_password_value);

            try {
                if(TriageApplicationMain.validateUser(username.getText().toString(),password.getText().toString(),getApplicationContext()))
                {
                Toast.makeText(StartActivity.this,
                        "Launching Triage Application", Toast.LENGTH_SHORT)
                        .show();
                startActivity(new Intent(StartActivity.this, MainActivity.class));
                }

                else
                     {
                    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                            StartActivity.this);


                        // set dialog message
                        alertDialogBuilder
                            .setMessage("Incorrect Credentials")
                            .setCancelable(false)
                            .setPositiveButton("OK",new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,int id) {
                                    // if this button is clicked, close
                                    // current activity
                                dialog.cancel();    
                                }
                              });


                            // create alert dialog
                            AlertDialog alertDialog = alertDialogBuilder.create();

                            // show it
                            alertDialog.show();

                    }
                }


            catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    });

}

I know this is a lot of code, but if anyone could help me here it would be great. This is for a school project.

PS: I have searched through Google for a solid hour before posting this so please don't criticize for not doing that. If you find a link that is useful then please share.

Just add android:inputType="..." to your EditText. It will work!! :)
