Enable button event by entering an Edit

Question

I created a "register" screen where the user informs the name/nickname and where there is a Continue button that goes to another screen. I would like this new screen to open when the user presses the Enter key, but I do not know how to do for the Enter key to have this function.

Below the code of the home screen

public class CadastroActivity extends AppCompatActivity {

EditText edtNome;

Button btnContinuar;

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

    edtNome = (EditText) findViewById(R.id.edtNome);

    btnContinuar = (Button) findViewById(R.id.btnContinuar);

    btnContinuar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent EnviarDados = new Intent(CadastroActivity.this, ResultadoActivity.class);

            String txtNome = edtNome.getText().toString();

            Bundle bundle = new Bundle();

            bundle.putString("nome", txtNome);

            EnviarDados.putExtras(bundle);

            startActivity(EnviarDados);

        }
    });
}

}

The best practice to achieve this is to use the event setOnEditorActionListener of EditText as shown this answer or this one here.

You will need to configure Edittext in XML (if not done) with the imeOptions corresponding to "next field".

<EditText
    android:id="@+id/editText2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:maxLines="1"
    android:imeOptions="actionNext" />

Note that here we set the property maxLines="1", that will make Android know that when pressing Enter, you must advance the field. The android:imeOptions="actionNext" changes the design of the "Enter" button with an arrow, indicating to the user that by clicking there it will be taken to the next field/screen/etc. Set this property in XML also sets the identification of the Edit event so that you can execute the action you want.

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_NEXT) {
            callAnotherActivity();
            return true;
        }
        return false;
    }
});
