百度地图通过点击得到地址
地理编码指的是将地址信息建立空间坐标关系的过程。有可分为正向地图编码和反向地图编码。 正向地理编码指的是由地址信息转换为坐标点的过程,反向编码则将经纬度转化为地址。
private BaiduMap bdMap;
bdMap.setOnMapClickListener(new BaiduMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng latLng) {
//Toast.makeText(getApplication(),latLng.longitude+","+latLng.latitude,Toast.LENGTH_SHORT).show();
initGEO(latLng);
}
@Override
public boolean onMapPoiClick(MapPoi mapPoi) {
Toast.makeText(getApplication(),mapPoi.getName(),Toast.LENGTH_SHORT).show();
return false;
}
});
public void initGEO(LatLng latLng)
{
GeoCoder mSearch=GeoCoder.newInstance();
OnGetGeoCoderResultListener listener = new OnGetGeoCoderResultListener() {
public void onGetGeoCodeResult(GeoCodeResult result) {
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
//没有检索到结果
}
//获取地理编码结果
}
@Override
public void onGetReverseGeoCodeResult(ReverseGeoCodeResult result) {
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
//没有找到检索结果
}
//获取反向地理编码结果
Toast.makeText(getApplication(),result.getAddress(),Toast.LENGTH_SHORT).show();
}
};
ReverseGeoCodeOption reverseGeoCodeOption=new ReverseGeoCodeOption();
mSearch.setOnGetGeoCodeResultListener(listener);
mSearch.reverseGeoCode(reverseGeoCodeOption.location(latLng));
}

android studio获取sha1
在CMD中输入keytool -list -v -keystore debug.keystore,
详情见:
注意
要找到正确的debug.keystore,由Android_SDK_HOME在环境变量中配置的路径为准。
定位
