With com.baidu.mapapi.map correlation function
According to the latitude and longitude to find the address information (call android map Baidu API)
For example: Given a coordinate GeoPoint mylocation = new GeoPoint ((int) (29.855 * 1E6),
(Int) (114.345 * 1E6)) ;/ /
Is there any way you can get the coordinates of the corresponding address information? Seek expert help! Thank you la la la!
To address the information given in great detail, can be as small to a building, such as "Baidu building." Seeking advice,

GeoPoint mylocation = new GeoPoint ((int) (29.855 * 1E6),
(Int) (114.345 * 1E6));
Search.reverseGeocode (mylocation);
Return result in MKSearchListener notification method in the onGetAddrResult

Upstairs: The ah, not detailed enough, can only be to an area to a building can not

Your function is to address the res is the detailed information

Upstairs Hello: This function can indeed get an address, but it is here to break out of the address Haman District Xianning City s208, I hope that the effect of Xianning Xianning City Haman District Road No. 88, Hubei Science and Technology College Library;
(2) When we click on the map when it will trigger
public void onClickMapPoi (MapPoi mapPoiInfo) {
/ / TODO Auto-generated method stub
String title = "";
if (mapPoiInfo! = null) {
title = mapPoiInfo.strText;
mylocation = mapPoiInfo.geoPt ;/ / modify the coordinates
Toast.makeText (LocationOverlayDemo.this, title,
. Toast.LENGTH_SHORT) show ();
}
This function can print out a very small place, such as Hubei Academy of Sciences Library; I want is this news, I hope I'll locate the position after a successful center of the map is automatically printed out, rather than after I click Print

In fact, check out the route, I want a specific coordinate point, seeking advice ah

The landlord did not solve the problem ah? Recently, I have been troubled by this issue, is obtained after Geocoder or by using latitude and longitude to visit Baidu homepage return address always have error ah! Is about 500 to 600 error! Can not pinpoint ah! Landlord seeking to rescue ah!
