Question

我正在研究一个Android项目，我需要设置我的地图放大并显示我的地图的更详细的视图，就像我希望我的坐标三角测量的街道。问题出在Mapview类中，不推荐使用setStreetView，是替代？这就是setStreetView在我使用它时的样子。

package com.HelloMapView;

import java.util.List;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;
import com.google.android.maps.OverlayItem;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.LinearLayout;

public class HelloMapView extends MapActivity {
    MapView mapview;
    LinearLayout linearlayout;
    List<Overlay> mapOverlay;
    Drawable drawable;
    HelloItemizedOverlay itemizedOverlay;
    @SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mapview=(MapView)findViewById(R.id.mapview);
        mapview.setBuiltInZoomControls(true);
        mapview.setStreetView(true);
        mapOverlay=mapview.getOverlays();
        drawable=this.getResources().getDrawable(R.drawable.androidmarker);
        itemizedOverlay=new HelloItemizedOverlay(drawable);
        GeoPoint geoPoint=new GeoPoint(19240000,-99120000);
        OverlayItem overlayitem=new OverlayItem(geoPoint,"","");
        itemizedOverlay.addoverlay(overlayitem);
        mapOverlay.add(itemizedOverlay);
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

这不起作用它只显示没有地图的方框

Answer 1

我知道它迟到但对将来的其他人有帮助如果你只看到灰色瓷砖而不是地图，那么问题在于你生成的密钥与代码无关，请参阅本教程了解kay http://www.youtube.com/watch?v=XdduYAs7klY这个用于街景http://mobiforge.com/developing/story/using-google-maps-android

Answer 2

使用MapView的 setStreetView（boolean）。

Answer 3

myMapView.setStreetView(true);

Answer 4

公共类ABC扩展了MapActivity {

private static MapController myMapController = null;
private static GeoPoint geoPoint = new GeoPoint

（（int）（25.24243399999999 * 1E6），（int）（55.30611937301637 * 1E6））;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.contact_us_layout);

    MapView mapView = (MapView) findViewById(R.id.mapview);
    mapView.displayZoomControls(false);
    mapView.setBuiltInZoomControls(true);
    mapView.setFocusable(true);
    myMapController = mapView.getController();
    myMapController.animateTo(geoPoint);
    myMapController.setZoom(15);
    // mapView.invalidate();
    // mapView.setFocusable(true);
    myMapController.setCenter(geoPoint);
    List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(
            R.drawable.mapmarker);
    HelloItemizedOverlay itemizedOverlay = new HelloItemizedOverlay(
            drawable, this);

    OverlayItem overlayItem = new OverlayItem(geoPoint,
            "abc");

    itemizedOverlay.addOverlay(overlayItem);


    mapOverlays.add(itemizedOverlay);

    //mapView.setSatellite(true);
    **mapView.setStreetView(true);**

公共类HelloItemizedOverlay扩展了ItemizedOverlay { private ArrayList mOverlays = new ArrayList（）; private Context mContext;

    public HelloItemizedOverlay(Drawable defaultMarker, Context context) {
        super(boundCenterBottom(defaultMarker));
        mContext = context;
    }

    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay);
        populate();
    }

    @Override
    protected OverlayItem createItem(int i) {
        return mOverlays.get(i);
    }

    @Override
    public int size() {
        return mOverlays.size();
    }

    @Override
    protected boolean onTap(int index) {
        OverlayItem item = mOverlays.get(index);
        AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
        dialog.setTitle(item.getTitle());
        dialog.setMessage(item.getSnippet());
        dialog.show();
        return true;
    }
}

}

您好,,, 我发布了你想要的工作代码...... 如果您的地图没有显示任何内容。您的api密钥未正确签名。请再次签名并在mapView中提供。如果你想使用streetView的地图： mapView.setStreetView（真）如果你想使用地图的satelliteView： mapView.setSatellite（真）

如何在我的mapview中设置streetView
