如何在MapView上设置诸如TitleWindow或BackButton之类的布局

Google MapView

StringBuffer mapUrl = new StringBuffer();

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mapUrl.append(\"http://maps.google.com/maps?\");
    mapUrl.append(\"saddr=\"+21.22794190505816+\",\"+72.8173828125);
    mapUrl.append(\"&daddr=\"+23.039297747769726+\",\"+72.59765);

    System.out.println(\"MapUrl: \"+mapUrl.toString());

    Intent i = new Intent(\"android.intent.action.VIEW\", Uri.parse(mapUrl.toString()));
    startActivity(i);
}
