地图

试下下面的代：

package com.liufeng.baidumap;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.GeoPoint;
import com.baidu.mapapi.MapActivity;
import com.baidu.mapapi.MapController;
import com.baidu.mapapi.MapView;
public class MainActivity extends MapActivity {
private BMapManager mapManager;
private MapView mapView;
private MapController mapController;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 初始化MapActivity
mapManager = new BMapManager(getApplication());
// init方法的第一个参数需填入申请的API Key
mapManager.init("285B415EBAB2A92293E85502150ADA7F03C777", null);
super.initMapActivity(mapManager);
mapView = (MapView) findViewById(R.id.map_View);
// 设置地图模式为交通地图
mapView.setTraffic(true);
// 设置启用内置的缩放控件
mapView.setBuiltInZoomControls(true);
// 用给定的经纬度构造一个GeoPoint（纬度，经度）
GeoPoint point = new GeoPoint((int) (47.118440 * 1E6), (int) (87.493147 * 1E6));
// 创建标记maker
Drawable marker = this.getResources().getDrawable(R.drawable.iconmarka);
// 为maker定义位置和边界
marker.setBounds(0, 0, marker.getIntrinsicWidth(), marker.getIntrinsicHeight());
// 取得地图控制器对象，用于控制MapView
mapController = mapView.getController();
// 设置地图的中心
mapController.setCenter(point);
// 设置地图默认的缩放级别
mapController.setZoom(12);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
@Override
protected void onDestroy() {
if (mapManager != null) {
mapManager.destroy();
mapManager = null;
}
super.onDestroy();
}
@Override
protected void onPause() {
if (mapManager != null) {
mapManager.stop();
}
super.onPause();
}
@Override
protected void onResume() {
if (mapManager != null) {
mapManager.start();
}
super.onResume();
}
}
