android 高德地图定位

1.首先必须做到能显示地图 https://mp.csdn.net/postedit/87184778
2.
// 设置定位监听
aMap.setLocationSource(this);

3.
// 在active方法中启动定位
@Override public void activate(OnLocationChangedListener onLocationChangedListener) {
mListener = onLocationChangedListener;
if (mlocationClient == null) {
//初始化定位
mlocationClient = new AMapLocationClient(_mActivity);
//初始化定位参数
mLocationOption = new AMapLocationClientOption();
//设置定位回调监听
mlocationClient.setLocationListener(this);
//设置为高精度定位模式
mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
//设置定位参数 mlocationClient.setLocationOption(mLocationOption);
// 此方法为每隔固定时间会发起一次定位请求，为了减少电量消耗或网络流量消耗，
// 注意设置合适的定位时间的间隔（最小间隔支持为2000ms），并且在合适时间调用stopLocation()方法来取消定位请求
// 在定位结束后，在合适的生命周期调用onDestroy()方法
// 在单次定位情况下，定位无论成功与否，都无需调用stopLocation()方法移除请求，定位sdk内部会移除 mlocationClient.startLocation();//启动定位
        }
}
aMap.setLocationSource(this);
