Как избавиться от наложения фрагментов друг на друга?

есть
public class MainActivity extends AppCompatActivity {
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
}

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();

        if (id == R.id.action_settings) {
            FragmentManager fm = getSupportFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();
            Fragment fragment = new SettingsActivityFragment();
            ft.replace(R.id.main, fragment);
            ft.commit();
        }

        return super.onOptionsItemSelected(item);
    }
}


код activity_main.xml
<fragment xmlns:android="http://schemas.android.com/apk/res/android"

    @Override

}


Собственно при клике на меню настроек, должен поменяться фрагмент. но происходит наложение двух фрагментов. Как исправить?
