我有这个问题,我没有看到任何错误的代码,但getLastKnownLocation空每次都返回。 有任何想法吗 ?
public class LocationDemo2Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
EditText et1 = (EditText) findViewById(R.id.editText1);
LocationManager manager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
Location location = manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(location != null) et1.setText((int)location.getLatitude());
else et1.setText("null");
}
}
谢谢
