LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates("gps", 60000, 1,locationListener); // 每秒更新位置信息，不考虑距离变化。
Location loc = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
locInfo.setText("维度："+String.valueOf(loc.getLatitude())+" 经度："+String.valueOf(loc.getLongitude()));
但是通常此时这里的loc为null，因此导致后面的经纬度信息获取不到从而产生NullPointExcetion. 目前我的解决办法是再多获取几次，不知道这算不算android的bug,一次获取位置信息获取不到，但是多获取几次就可以获取到了。代码如下：
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location loc = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
while (loc == null) {
locationManager.requestLocationUpdates("gps", 60000, 1,
locationListener); // 每秒更新位置信息，不考虑距离变化。
loc = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
}
这个是上面所提到的locationListener，我这里是做个例子，什么也没干。
private void initlocationListener() {
locationListener = new LocationListener() {
// implement necessary methods
public void onLocationChanged(Location location) {
locInfo.setText("维度："+String.valueOf(location.getLatitude())+" 经度："+String.valueOf(location.getLongitude()));
}
public void onProviderDisabled(String provider) {
// called when the provider be disabled by user
}
public void onProviderEnabled(String provider) {
// called when the provider be enabled
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
};
}
