如何缩放openstreet地图？我的下面的代码只有mapview.builinzoom控件（TRUE）

如何在googlemapview中提供我的缩放级别，有一个像

这样的功能

MapController mc = mapView.getController();
mc.setZoom(15);

那么如何在openstreet map中添加此类型函数，以便在启动应用程序时它已经缩放并向我显示正确的结果？

import org.osmdroid.DefaultResourceProxyImpl;
import org.osmdroid.ResourceProxy;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapView;

import com.google.android.maps.MapController;


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

public class MainActivity extends Activity {

 MyItemizedOverlay myItemizedOverlay = null;

 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    MapView mapView = (MapView) findViewById(R.id.mapview);
    mapView.setBuiltInZoomControls(true);


    Drawable marker=getResources().getDrawable(android.R.drawable.star_big_on);
    int markerWidth = marker.getIntrinsicWidth();
    int markerHeight = marker.getIntrinsicHeight();
    marker.setBounds(0, markerHeight, markerWidth, 0);

    ResourceProxy resourceProxy = new       
   DefaultResourceProxyImpl(getApplicationContext());

    myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy);
    mapView.getOverlays().add(myItemizedOverlay);

    GeoPoint myPoint1 = new GeoPoint(24.893379000000000000, 67.028060900000010000);
    myItemizedOverlay.addItem(myPoint1, "myPoint1", "myPoint1");
    GeoPoint myPoint2 = new GeoPoint(24.824796300000000000, 67.031565699999990000);
    myItemizedOverlay.addItem(myPoint2, "myPoint2", "myPoint2");


    } 

   }

Answer 1

请参阅API，特别是IMapView和IMapController接口。你应该得到这样的东西：

mapView.getController().setZoom(16);

Answer 2

U禁用此行并为您的应用程序运行，

 mapView.setBuiltInZoomControls(true);

Answer 3

不要在xml中创建mapview，在xml中没有为我设置拖动地图和缩放控件。

但是，像这个例子一样以编程方式创建，对我有用。
