本以为很繁难的，结果即是百度曾经供应了：地舆编码&反地舆编码的接口。

mSearch.geocode(new GeoCodeOption().city(

editCity.getText().toString()).address(

editGeoCodeKey.getText().toString()));

mSearch.reverseGeoCode(new ReverseGeoCodeOption()

.location(ptCenter));

之后只必要重写onGetGeoCodeResult(GeoCodeResult result)和onGetReverseGeoCodeResult(ReverseGeoCodeResult result)就可以对正反编码举行自定义处分
