我有一个程序使用 GPS 每 2 分钟定位一个人。为此,代码是:
private boolean flagLocalizacion = false;
private LocationListener locationListener;
private Location ultimaLocalizacion;
private LocationManager locationManager;
@Override
public void onCreate(Bundle savedInstanceState) {
locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
if (location!=null) {
if(ultimaLocalizacion == null && flagLocalizacion) {
ultimaLocalizacion = location;
Toast.makeText(getApplicationContext(), "Longitude: " + location.getLongitude() + "Latitude: " + location.getLatitude(), Toast.LENGTH_SHORT).show();
} else if ((ultimaLocalizacion.getLatitude() != location.getLatitude()
|| ultimaLocalizacion.getLongitude() != location.getLongitude()) && flagLocalizacion) {
ultimaLocalizacion = location;
Toast.makeText(getApplicationContext(), "Longitude: " + location.getLongitude() + "Latitude: " + location.getLatitude(), Toast.LENGTH_SHORT).show();
}
}
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {
System.out.println("gps");
}
public void onProviderDisabled(String provider) {
System.out.println("No gps");
}
}; Button botonComenzar = (Button) findViewById(R.id.bComenzar);
botonComenzar.setOnClickListener(new OnClickListener() {
@SuppressWarnings("static-access")
public void onClick(View v) {
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(locationManager.GPS_PROVIDER, 12000, 30, locationListener);
Toast.makeText(getApplicationContext(), "Activada Localizacion", Toast.LENGTH_SHORT).show();
flagLocalizacion = true;
}
});
我的问题是:
此应用程序在 2.2 版中正常工作。但是当我将它安装在具有 2.3.5. 的手机中时,该软件失败了,失败是那个 localice 不断地,而不是每 2 分钟一次。你有没有想过为什么会这样?
谢谢。
