Checkbox approval

I want a checkbox to be checked before they can continue to go to the next page (XML). It is working seperate but not together. In the sence that if I push the play button without a checked checkbox, it should only show the toast. This is what I got.

XML checkbox has itemClicked aas onClick method Button has startNewActivity as onClick method.

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

public void itemClicked (View v) {
    final Button play =(Button)findViewById(R.id.playButton);
    CheckBox Approved = (CheckBox) findViewById(R.id.Approved);
    Approved.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (((CheckBox) v).isChecked()) {
                play.setEnabled(true);

            } else {
                Toast.makeText(MainActivity.this, "Please Approve!", Toast.LENGTH_LONG).show();
            }
        }
    });
}

public void startNewActivity (View view){
    final EditText edit = (EditText) findViewById(R.id.editText);
    String Name = (String) edit.getText().toString();

    Intent intent = new Intent (this, GameSetUp.class);
    intent.putExtra("name", Name);

    itemClicked(view);
    startActivity(intent);
}

}

Please can you tell what I am doing wrong.
