Expression Expected error

Question

In Android Studio I want to a button to start a new Activity. I get an Expression Expected error. Where have I gone wrong?

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

  Button advanceToQuestionTwo = {Button};

  Button loadNewActivity = (Button) findViewById(R.id.imageButton);

  loadNewActivity.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View view) {
      Intent intent = new Intent(MainActivity.this, Stundenplan.class);
      startActivity(intent);
    }
  });
}

Solution

You must delete this line Button advanceToQuestionTwo = {Button}; or complete it. You need to put (Button) and not {Button}. Then after that you should call findViewById( id of that button in the xml file).
