重点关注
通过系统的方向传感器获取到方向角度，结合地图SDK中的定位图层功能实现方向指向。
核心代码
1.开启定位图层设置定位模式
JAVA
mBaiduMap.setMyLocationEnabled(true);
MyLocationConfiguration myLocationConfiguration = new MyLocationConfiguration(MyLocationConfiguration.LocationMode.NORMAL, true, null);

2.获取传感器管理服务注册方向传感监听器
JAVA
// 获取传感器管理服务
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
// 为系统的方向传感器注册监听器
mSensorManager.registerListener(this, mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
SensorManager.SENSOR_DELAY_UI);

3.获取传感器方向回调信息设置给定位图层
JAVA
/**
* 传感器方向信息回调
*/
@Override
public void onSensorChanged(SensorEvent sensorEvent) {
double x = sensorEvent.values[SensorManager.DATA_X];
if (Math.abs(x - lastX) > 1.0) {
mCurrentDirection = (float) x;
// 构造定位图层数据
myLocationData = new MyLocationData.Builder()
.accuracy(mCurrentAccracy)
// 此处设置开发者获取到的方向信息，顺时针0-360
.direction(mCurrentDirection)
.latitude(mCurrentLat)
.longitude(mCurrentLon).build();
// 设置定位图层数据
mBaiduMap.setMyLocationData(myLocationData);
}
lastX = x;
