我创建了以下扩展 MapActivity 的类。错误在这个类中
查看视图 = infalInflater.inflate(R.layout.car_map_view, null);
public class ShowCarMapChild extends MapActivity {
private MapView mapView;
private Car car;
private String tag;
@Override
protected void onCreate(Bundle icicle) {
// TODO Auto-generated method stub
super.onCreate(icicle);
setContentView(R.layout.car_map_view);
}
public void setCar(Car car){
this.car = car;
}
public void setTag (String tag){
this.tag = tag;
}
public String getTag (){
return tag;
}
public View getMapView(Context context){
LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View view = infalInflater.inflate(R.layout.car_map_view, null);
setMap(view,context);
return view;
}
public void setMap(View view, Context context){
mapView = (MapView) view.findViewById(R.id.mapShowCarLocation);
MapController mc = mapView.getController();
mc.animateTo(car.getLocation());
mc.setZoom(15);
PinpointItem point = new PinpointItem(car.getLocation(), car, context);
Drawable d = getResources().getDrawable(R.drawable.pinpoint);
CustomPinpointOverlay overlay = new CustomPinpointOverlay(d);
overlay.insertPinpoint(point);
mapView.getOverlays().add(overlay);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
这是xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="150dip"
