Android百度地图深入学习（1）

学习一门新的技术，最好参考官方的文档。

这是百度地图官方参考资料：http://lbsyun.baidu.com/index.php?title=androidsdk/guide/hellobaidumap

一、实现普通地图、卫星地图、实时交通

大体实现步骤：

1、将百度地图引入到我们的app中去

2、通过菜单选项实现普通地图、卫星地图、实时交通的开关

源码实现：

/baidudemo/res/layout/activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

  <com.baidu.mapapi.map.MapView  
    android:id="@+id/bmapView"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    android:clickable="true" />

</RelativeLayout>

/baidudemo/res/menu/main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/id_map_common"
        android:showAsAction="never"
        android:title="普通地图"/>
    <item
        android:id="@+id/id_map_site"
        android:showAsAction="never"
        android:title="卫星地图"/>
    <item
        android:id="@+id/id_map_traffic"
        android:showAsAction="never"
        android:title="实时交通(off)"/>

</menu>

			break;
		case R.id.id_map_site:
			mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);
			break;
		case R.id.id_map_traffic:
			if(mBaiduMap.isTrafficEnabled()){//为true，可以进行实时交通。
				//菜单项再点击一次就不能进行实时交通，并修改显示信息
				mBaiduMap.setTrafficEnabled(false);
				item.setTitle("实时交通(off)");
			}else{
				mBaiduMap.setTrafficEnabled(true);
				item.setTitle("实时交通(on)");
			}
			break;

		default:
			break;
		}
		return super.onOptionsItemSelected(item);
	}
}

运行效果：

二、定位功能，定位我的位置

实现所需的类：

LocationClient、LocationClientOption进行定位的一些设置、BDLocationListener、BDLocation、MyLocationData。

代码实现：

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/id_map_common"
        android:showAsAction="never"
        android:title="普通地图"/>
    <item
        android:id="@+id/id_map_site"
        android:showAsAction="never"
        android:title="卫星地图"/>
    <item
        android:id="@+id/id_map_traffic"
        android:showAsAction="never"
        android:title="实时交通(off)"/>
    <item
        android:id="@+id/id_map_location"
        android:showAsAction="never"
        android:title="我的位置"/>

运行效果：

模式切换：

普通模式、跟随模式、罗盘模式。

大概方法：

MyLocationConfiguration config = new MyLocationConfiguration(mLocationMode,true,mIconLocation);

mBaiduMap.setMyLocationConfigeration(config);
