我正在尝试学习如何为谷歌地图v2实施位置服务,但我不是很成功。
我遵循了这个指南 - http://www.youtube.com/watch?v=wKz04cs660E,我发现错误,方法getController()未定义为MapView类型
我已阅读Maps V2的文档但我找不到解决方案。
这是我的代码
package com.example.gpslocation;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.maps.MapController;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.Menu;
public class GPSLocMainActivity extends android.support.v4.app.FragmentActivity implements LocationListener {
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gpsloc_main);
MapView view=(MapView) findViewById(R.id.map);
map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
//final MapController control=view.getController();
final MapController control = view.getController();
LocationManager manager=(LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
LocationListener listener=new LocationListener(){
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
control.setCenter(new com.google.android.maps.GeoPoint((int)location.getLatitude(), (int) location.getLongitude()));
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
};
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, listener);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.gpsloc_main, menu);
return true;
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
提前致谢:)
好吧所以我解决了这个问题,这很容易做到这里是我的新代码,它在屏幕上显示一个小标记
package com.example.gpslocation;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.location.Location;
import android.location.LocationListener;
import android.os.Bundle;
import android.view.Menu;
public class GPSLocMainActivity extends android.support.v4.app.FragmentActivity implements LocationListener {
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gpsloc_main);
map=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
MapFragment MapFrag=(MapFragment) getFragmentManager().findFragmentById(R.id.map);
map=MapFrag.getMap();
map.setMyLocationEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
}
@Override
public void onLocationChanged(Location location)
{
// TODO Auto-generated method stub
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.gpsloc_main, menu);
return true;
}
}

您所关注的指南不是您应该关注的指南,因为它不再具有相关性。视频显示的是旧的谷歌地图v1,不再使用。
如果你想使用v2,你应该查看文档
https://developers.google.com/maps/documentation/android/
Google Play服务文件夹中还有一个示例应用,您从ADT下载了Google Play服务
