调用百度地图

今天学习了百度的一些基本的用法，感觉百度给的东西对开发者的使用非常方便。

包括百度地图的调用，在地图中添加图片，位置的移动，以及地图位置的发送

首先，前期准备，

需要如上的准备，可以去百度lbsyun.baidu.com自己下载，百度也有提供的案例供参考

直接上代码：

DemoApplication

public class DemoApplication extends Application {

	@Override
	public void onCreate() {
		super.onCreate();
		// 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContext
		SDKInitializer.initialize(this);
	}

}

MainActivity

public class MainActivity extends Activity {
	LocationClient lc;
	MapView mapView;
    BaiduMap baiduMap;
    Button btnSend;
    ImageView imageview;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.show_map);
        btnSend = (Button) findViewById(R.id.button1);
        imageview = (ImageView) findViewById(R.id.imageView1);
		mapView = (MapView) findViewById(R.id.baidu_map);
		baiduMap = mapView.getMap();
		MyListener ml = new MyListener();
		lc = new LocationClient(this);
		lc.registerLocationListener(ml);

		LocationClientOption option = new LocationClientOption();
		option.setOpenGps(true);
		option.setCoorType("bd09ll");
		option.setScanSpan(3000);
		lc.start();
		baiduMap.setOnMapClickListener(new OnMapClickListener() {
			
			@Override
			public boolean onMapPoiClick(MapPoi arg0) {
				// TODO Auto-generated method stub
				return false;
			}
			
			@Override
			public void onMapClick(LatLng click) {
				// TODO Auto-generated method stub
			   //单击的位置添加图片
				baiduMap.clear();
				MarkerOptions mos = new MarkerOptions();
				mos.position(click);
				mos.icon(BitmapDescriptorFactory.fromResource(R.drawable.tubiao1));
				baiduMap.addOverlay(mos);
			}
		});
		//对按钮做出响应
		btnSend.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				baiduMap.snapshot(new SnapshotReadyCallback() {
					
					@Override
					public void onSnapshotReady(Bitmap bitmap) {
						// TODO Auto-generated method stub
						imageview.setImageBitmap(bitmap);
					}
				});
			}
		});
	}

	class MyListener implements BDLocationListener {

		@Override
		public void onReceiveLocation(BDLocation bdLocation) {
			// TODO Auto-generated method stub
			//获取纬度
			double latitude = bdLocation.getLatitude();
			//获取经度
			double longitude = bdLocation.getLongitude();
			for(int i =1;i<=100;i++){
		   System.out.println("纬度" + latitude + "经度" + longitude);
			}
		  //虚拟机上边得不到真实的数据
		   //移动地图中心点
		   LatLng currentPosition = new LatLng(latitude, longitude);
		   MapStatusUpdate mapStatusUpdate = MapStatusUpdateFactory.newLatLngZoom(currentPosition, 17);
		   baiduMap.animateMapStatus(mapStatusUpdate);
		   //在地图上显示图片
		   MarkerOptions mo = new MarkerOptions();
		   mo.position(currentPosition);
		   //将图片加入到地图中
		   mo.icon(BitmapDescriptorFactory.fromResource(R.drawable.tubiao1));
		   baiduMap.addOverlay(mo);
		}

	}
}

布局设置：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="fill_parent"
        android:layout_height="200dp"
        android:src="@android:drawable/btn_dialog" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="发送地图" />
    <com.baidu.mapapi.map.MapView
        android:id="@+id/baidu_map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"></com.baidu.mapapi.map.MapView>

</LinearLayout>

AndroidMainfest.xml,这里边的东西很重要，还需要自己申请一个key,
