Android引路蜂地图开发示例：放大、缩小

RasterMap的 zoomIn,zoomOut 用来放大缩小地图。在项目GISEngineTutorial中创建MapZoom Activity。

package com.pstreets.gisengine.demo; import com.mapdigit.gis.geometry.GeoLatLng;import com.pstreets.gisengine.R;import com.pstreets.gisengine.SharedMapInstance;import com.mapdigit.gis.raster.MapType;import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.MenuInflater;import android.view.MenuItem; public class MapZoom extends Activity {  @Override public void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.main);      }  @Override public void onStart() {  super.onStart();  GeoLatLng center = new GeoLatLng(32.0616667, 118.7777778);  SharedMapInstance.map.setCenter(center, 13, MapType.MICROSOFTCHINA);  }  @Override public boolean onCreateOptionsMenu(Menu menu) {  MenuInflater inflater = getMenuInflater();  inflater.inflate(R.menu.mapzoom_menu, menu);  return true; }  @Override public boolean onOptionsItemSelected(MenuItem item) {  // Handle item selection  switch (item.getItemId()) {  case R.id.zoomin:   SharedMapInstance.map.zoomIn();    return true;  case R.id.zoomout:   SharedMapInstance.map.zoomOut();   return true;   default:   return super.onOptionsItemSelected(item);  }  } }
