描述

ReverseGeoCodeOption

location(LatLng location)

设置反地理编码位置坐标

ReverseGeoCodeOption

newVersion(int latestAdmin)

设置是否返回新数据0不返回，1返回默认值0

ReverseGeoCodeOption

radius(int radius)

设置POI召回半径

GeoCoder

newInstance()

创建地理编码查询实例

GeoCoder

reverseGeoCode(ReverseGeoCodeOption option)

发起反地理编码请求(经纬度->地址信息)

GeoCoder

setOnGetGeoCodeResultListener(OnGetGeoCoderResultListener listener)

设置查询结果回调

GeoCoder

destroy()

销毁函数

重点关注

务必在Activity的onDestroy函数里，调用MapView和GeoCoder的销毁方法，否则会有内存泄露。

JAVA

@Override
protected void onDestroy(){
    super.onDestroy();

    if(null!= mGeoCoder){
        mGeoCoder.destroy();
    }

    if(null!= mMapView){
        mMapView.onDestroy();
    }
}

核心代码

1.发起逆地理编码请求

JAVA

/**
/**
* 逆地理编码请求
* @param latLng
*/
private void reverseRequest(LatLng latLng){
    if(null == latLng){
        return;
    }

    ReverseGeoCodeOption reverseGeoCodeOption = new ReverseGeoCodeOption().location(latLng)
            .newVersion(1)
            .radius(sDefaultRGCRadius)
            .pageNum(mLoadIndex);

    if(null == mGeoCoder){
        mGeoCoder = GeoCoder.newInstance();
    }

    mGeoCoder.setOnGetGeoCodeResultListener(this);
    mGeoCoder.reverseGeoCode(reverseGeoCodeOption);
}

2.逆地理编码请求回调处理

JAVA

/**
@Override
public void onGetReverseGeoCodeResult(final ReverseGeoCodeResult reverseGeoCodeResult) {
    if (null == reverseGeoCodeResult) {
        return;
    }

    mHandler.post(new Runnable() {
        @Override
        public void run() {
            updateUI(reverseGeoCodeResult);
        }
    });
}
