将简单的 GoogleMaps 应用程序与核心应用程序集成时出错
我正在做我的 GPS 应用程序。带有 GoogleMaps 的独立应用程序运行顺利（地图意图很容易调用）。我尝试将其集成到我的核心应用程序（它有几个其他意图）中，但在启动它时遇到问题。
我已经尝试过：
public class MapaG extends Activity {
public class MapaG1 extends MapActivity {
private static final int latitudeE6= 50656428;
private static final int longitudeE6 = 17899562;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.widokmapy);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
NakladkaNaMape itemizedOverlay = new NakladkaNaMape(drawable, this);
GeoPoint point = new GeoPoint(latitudeE6, longitudeE6);
OverlayItem overlayitem = new OverlayItem(point, "Witaj w Opolu", "Polska");
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
MapController mapController = mapView.getController();
mapController.animateTo(point);
mapController.setZoom(12);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
}
LogCat 视角为我提供了未找到 Activity 的信息：
FATAL EXEPTION: main android.content.ActivityNotFoundException: No Activity found handle Intent {act=praca.dyp.k.d.MAPAG}
I'm doing my GPS app. Standalone app with GoogleMaps works smoothly (map intent is easy to invoke). I tried integrating it my core app (which has several other intents) and I'm having problem launching it.
I've tried this:
public class MapaG extends Activity {
public class MapaG1 extends MapActivity {
private static final int latitudeE6= 50656428;
private static final int longitudeE6 = 17899562;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.widokmapy);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
NakladkaNaMape itemizedOverlay = new NakladkaNaMape(drawable, this);
GeoPoint point = new GeoPoint(latitudeE6, longitudeE6);
OverlayItem overlayitem = new OverlayItem(point, "Witaj w Opolu", "Polska");
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
MapController mapController = mapView.getController();
mapController.animateTo(point);
mapController.setZoom(12);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
}
LogCat perspective gives me info that no Activity was found:
FATAL EXEPTION: main android.content.ActivityNotFoundException: No Activity found handle Intent {act=praca.dyp.k.d.MAPAG}

我想知道为什么要在 Activity 中创建 MapActivity 类？删除外部活动类声明。保留 MapActivity 类。在清单中使用适当的权限。
I'm wondering why you are creating a MapActivity class inside an Activity? Remove the outer activity class declaration. Keep the MapActivity class. Use proper permissions in Manifest.
您是否在 AndroindManifest.xml 文件中添加了 MapAcitivity？
您还需要将其包含在清单中：
您可以在此处查看更详细的示例：
HelloWorld，MapActivity
Did you add your MapAcitivity in your AndroindManifest.xml file?
You also need to include this in your manifest:
