Question

我搜索了网站，但仍然没有找到我的问题的任何答案。你能告诉我为什么mapa在这里无法解决？

       mapa.setSatelite(true);

以下是整个活动代码：

  package rs.iz.stevy.wifi;

  import android.graphics.drawable.Drawable;
  import android.os.Bundle;
  import android.view.Menu;
  import android.view.MenuInflater;
  import android.view.MenuItem;


  public class WiFiKupacicaActivity extends MapActivity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    MapView mapa= (MapView) findViewById(R.id.Mapa1);
    mapa.setBuiltInZoomControls(true);
    mapa.setSatellite(false);

List<Overlay> mapOverlays = mapa.getOverlays();
Drawable drawable = this.getResources().getDrawable(R.drawable.green);//dodaj neki marker
MapOverlay itemizedoverlay = new  MapOverlay(drawable, this);
