百度SDK地图定位

1.关于百度定位，首先要在百度开发者中心那里新申请一个应用并且下载相对应的sdk

得到一个APP Key作为应用的唯一标示

2.在应用的清单文件里面加上这段话

<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="your app key" />
//填入你的app key

3.加上对应的权限

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS" />

public class BaseApplication extends Application{
@Override
public void onCreate() {
super.onCreate();
//在使用SDK各组件之前初始化context信息，传入ApplicationContext
//注意该方法要再setContentView方法之前实现
SDKInitializer.initialize(getApplicationContext());
}
}

public class LocationActivity extends Activity{
MapView mMapView;
BaiduMap mBaiduMap;
LocationClient mLocClient;
public MyLocationListenner myListener = new MyLocationListenner();
private boolean isFirst = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMapView = (MapView) findViewById(R.id.mapview);
mBaiduMap = mMapView.getMap();
// 开启定位图层
mBaiduMap.setMyLocationEnabled(true);
// 定位初始化
mLocClient = new LocationClient(getApplicationContext());
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);
option.setIsNeedAddress(true);
option.setOpenGps(true);
mLocClient.setLocOption(option);
mLocClient.start();
}
/**
* 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;
}
MyLocationData 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(100).latitude(location.getLatitude())
.longitude(location.getLongitude()).build();
mBaiduMap.setMyLocationData(locData);
isFirst = false;
LatLng ll = new LatLng(location.getLatitude(),
location.getLongitude());
MapStatus.Builder builder = new MapStatus.Builder();
builder.target(ll).zoom(11.0f);
mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
}
public void onReceivePoi(BDLocation poiLocation) {
}
}
@Override
protected void onDestroy() {
super.onDestroy();
// 退出时销毁定位
mLocClient.stop();
// 关闭定位图层
mBaiduMap.setMyLocationEnabled(false);
mMapView = null;
mMapView.onDestroy();
}
@Override
protected void onResume() {
super.onResume();
mMapView.onResume();
}
@Override
protected void onPause() {
super.onPause();
mMapView.onPause();
}
}
