Android : how to implement insert means enter on editext

am trying to implement a method that goes to the next activity after finishing filling a EditText then Pressing Enter on Phone's key board.

public class Multiplayer extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_multiplayer);
}


public void getText(View v){


   /**
     * here is "myEdittext" whom am trying from it  
     * to go to my "multiIntent" Activity
     * after pressing Enter
     */

    EditText myEditText =(EditText) findViewById(R.id.editTextWord);

    String letter = myEditText.getText().toString();

    myEditText.setText("");

    letter.toUpperCase();

    Intent multiIntent = new Intent(this,GameMultiActivity.class);

    multiIntent.putExtra("nWords",letter);

    startActivity(multiIntent);


}}

Any Suggestions :) .
