百度地图SDK集成及根据坐标实现定位(android studio开发)

1.下载百度地图SDK

链接:http://lbsyun.baidu.com/index.php?title=androidsdk

根据自己需求下载SDK

2.集成步骤:

      1.ak**获取参考百度官网:http://lbsyun.baidu.com/index.php?title=androidsdk/guide/create-project/ak

      2.android studio配置参考:http://lbsyun.baidu.com/index.php?title=androidsdk/guide/create-project/androidstudio

      3.配置AndroidMainfest.xml文件配置可参考:http://lbsyun.baidu.com/index.php?title=androidsdk/guide/create-project/hellomap

将以下权限拷贝到AndroidMainfest.xml文件中:

在application中添加**:value填写获取的key(进入百度控制台)

build.gradle里面需要指定so文件的路径

sourceSets{
    main{
        jniLibs.srcDir 'libs'
        //说明so的路径为该libs路径，关联所有地图SDK的so文件
    }
}

        4.在application中进行初化:

    代码:SDKInitializer.initialize(getApplicationContext());

3.实现定位功能:

在xml文件中添加控件:

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

java文件中代码:

/**
 * 定位SDK监听函数
 */
public class MyLocationListenner implements BDLocationListener {

    @Override
    public void onReceiveLocation(BDLocation location) {
        // map view 销毁后不在处理新接收的位置
        if (location == null || mMapView == null) {
            return;
        }
        mCurrentLat = location.getLatitude();
        mCurrentLon = location.getLongitude();
        mCurrentAccracy = location.getRadius();
        locData = new MyLocationData.Builder()
                .accuracy(location.getRadius())
                // 此处设置开发者获取到的方向信息，顺时针0-360
                .direction(mCurrentDirection).latitude(location.getLatitude())
                .longitude(location.getLongitude()).build();
        mBaiduMap.setMyLocationData(locData);
        if (isFirstLoc) {
            isFirstLoc = false;
            LatLng ll = new LatLng(location.getLatitude(),
                    location.getLongitude());
            MapStatus.Builder builder = new MapStatus.Builder();
            builder.target(ll).zoom(18.0f);
            mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
        }
    }

    public void onReceivePoi(BDLocation poiLocation) {
    }
}

mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);//获取传感器管理服务
mCurrentMode = LocationMode.NORMAL;//地图显示模式:普通
mCurrentMarker = null;//null为默认
mCurrentMarker = BitmapDescriptorFactory.fromResource(R.drawable.icon_geo);//自定义显示定位图标
accuracyCircleFillColor = 0xAAFFFF88;
accuracyCircleStrokeColor = 0xAA00FF00;

// 地图初始化
mMapView = (MapView) findViewById(R.id.bmapView);
mBaiduMap = mMapView.getMap();
// 开启定位图层
mBaiduMap.setMyLocationEnabled(true);
// 定位初始化
mLocClient = new LocationClient(this);
mLocClient.registerLocationListener(myListener);
LocationClientOption option = new LocationClientOption();
option.setOpenGps(true); // 打开gps
option.setCoorType("bd09ll"); // 设置坐标类型
option.setScanSpan(1000);
mLocClient.setLocOption(option);
mLocClient.start();

以上代码可实现通过网络或者gps进行自动定位

4.根据所给百度地图坐标实现定位

测试坐标搜索链接:http://www.gpsspg.com/maps.htm

例:

java中的代码:

直接传入纬度和经度即可

public void UpDate(double currentlat, double currentlon) {
    locData = new MyLocationData.Builder()
            .accuracy(188.0f)
            // 此处设置开发者获取到的方向信息，顺时针0-360
            .direction(mCurrentDirection).latitude(currentlat)
            .longitude(currentlon).build();
    mBaiduMap.setMyLocationData(locData);
    LatLng ll = new LatLng(currentlat,
            currentlon);
    MapStatus.Builder builder = new MapStatus.Builder();
    builder.target(ll).zoom(18.0f);
    mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
}
