用于获取GPS的requestLocationUpdates不起作用

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (!isGPSEnabled) {
    Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
    startActivity(intent);
}

LocationListener locationListener = new LocationListener() {
    @Override
    public void onLocationChanged(Location location) {
        // 处理位置更新
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        // 处理状态变化
    }

    @Override
    public void onProviderEnabled(String provider) {
        // 处理提供者启用
    }

    @Override
    public void onProviderDisabled(String provider) {
        // 处理提供者禁用
    }
};

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
