取得LocationProvider
Java代码

1. public void getLocationProvider()
2. {
3. try
4. {
5. Criteria mCriteria01 = new Criteria();
6. mCriteria01.setAccuracy(Criteria.ACCURACY_FINE);
7. mCriteria01.setAltitudeRequired(false);
8. mCriteria01.setBearingRequired(false);
9. mCriteria01.setCostAllowed(true);
10. mCriteria01.setPowerRequirement(Criteria.POWER_LOW);
11. strLocationProvider =
12. mLocationManager01.getBestProvider(mCriteria01, true);
14. mLocation01 = mLocationManager01.getLastKnownLocation
15. (strLocationProvider);
16. }
17. catch(Exception e)
18. {
19. mTextView01.setText(e.toString());
20. e.printStackTrace();
21. }
22. }

获取经纬度，并返回GeoPoint对象
Java代码

1. private GeoPoint getGeoByLocation(Location location)
2. {
3. GeoPoint gp = null;
4. try
5. {
7. if (location != null)
8. {
9. double geoLatitude = location.getLatitude()*1E6;
10. double geoLongitude = location.getLongitude()*1E6;
11. gp = new GeoPoint((int) geoLatitude, (int) geoLongitude);
12. }
13. }
14. catch(Exception e)
