Android 如何用FusedLocationProviderClient替换FusedLocationApi?,android,google-maps,location,fusedlocationproviderapi,Android,Google Maps,Location,Fusedlocationproviderapi,我想在已连接的网络上查找当前位置。我目前使用的FusedLocationApi已被弃用。我必须使用requestLocationUpdate方法,但在使用FusedLocationProviderClient时出现一些语法错误。我还必须在onPause和onDestroy中使用removeLocationupdate 这是我当前使用FusedLocationProviderClient的代码- @Override public void onConnected(@Nullable Bundle

我想在已连接的网络上查找当前位置。我目前使用的FusedLocationApi已被弃用。我必须使用requestLocationUpdate方法,但在使用FusedLocationProviderClient时出现一些语法错误。我还必须在onPause和onDestroy中使用removeLocationupdate

这是我当前使用FusedLocationProviderClient的代码-

@Override
public void onConnected(@Nullable Bundle bundle) {
    mLocationRequest = LocationRequest.create();
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    mLocationRequest.setInterval(1000);
    mLocationRequest.setFastestInterval(1000);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
   LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleClientApi, mLocationRequest, this);
    if (mCurrentLocMarker == null) {
        Location loc = LocationServices.FusedLocationApi.getLastLocation(mGoogleClientApi);
        mLastLocation = loc;
        if (loc != null) {
            LatLng latLng = new LatLng(loc.getLatitude(), loc.getLongitude());
            MarkerOptions markerOptions = new MarkerOptions();
            markerOptions.position(latLng);
            markerOptions.title("Current Location");
            markerOptions.flat(true);
            int height = 150;
            int width = 150;
            BitmapDrawable bitmapDrawable = (BitmapDrawable)getResources().getDrawable(R.drawable.icon_navigation);
            Bitmap bitmap = bitmapDrawable.getBitmap();
            Bitmap marker = Bitmap.createScaledBitmap(bitmap, width, height, false);
            markerOptions.icon(BitmapDescriptorFactory.fromBitmap(marker));
            markerOptions.anchor(0.5f, 0.5f);
            mCurrentLocMarker = mMap.addMarker(markerOptions);
            CameraPosition cameraPosition = new CameraPosition.Builder()
                    .target(latLng)
                    .zoom(17)
                    .build();
            mMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
        }

    }
}
@Override
protected void onPause() {
    super.onPause();
    mapView.onPause();
    String trackid = SharedPreferenceManager.getmInstance(this).getTrackId();
    if (mGoogleClientApi != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleClientApi,this);
    }
    if (!trackid.equals("NO DATA")) {
        startService(new Intent(this, LocationService.class));
    }
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
    String trackid = SharedPreferenceManager.getmInstance(this).getTrackId();
    if (mGoogleClientApi != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleClientApi, this);
    }
    if (!trackid.equals("NO DATA")) {
        startService(new Intent(this, LocationService.class));
    }
}
这是我尝试过的,但无法实现其requestLocationUpdate和removeLocationUpdate:

FusedLocationProviderClient fusedLocationProviderClient; //Global variable
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); //initiate in onCreate

你的开始就像你需要的那样

FusedLocationProviderClient fusedLocationProviderClient; //Global variable
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); //initiate in onCreate
要从另一个应用程序以谷歌地图的形式获取位置,您可以使用
mFusedLocationClient.getLastLocation()
它有监听器,
addOnSuccessListener
提供给您位置,
addOnCompleteListener
task.getResult()==null
表示您需要执行自己的请求,如
mFusedLocationClient.RequestLocationUpdate(getLocationRequest(),mlLocationCallback,null)

例如,您需要在onPause中删除侦听器,如
mFusedLocationClient.removeLocationUpdates(mLocationCallback)

你可以看看这个例子

是的,我是这样理解的,但我对mlocationcallback的对象位置callback有点困惑,它来自
com.google.android.gms.location.LocationCallbacknewlocationcallback()
,这样您就可以用locationResult覆盖方法
onLocationResult
。如果您的
locationResult==null
位置服务将关闭,您需要解决它。在另一种情况下,您需要by locationResult.getLocations(),您将获得location.getLatitude()和location.getLatitude(),是的,我得到了它,但我对mlocationCallback的对象LocationCallback有点困惑,它来自
com.google.android.gms.location.LocationCallbacknewlocationcallback()
,这样您就可以用locationResult覆盖方法
onLocationResult
。如果您的
locationResult==null
位置服务将关闭,您需要解决它。在另一种情况下,您需要按locationResult.getLocations()进行排序,然后将得到location.getLatitude()和location.getLongitude()
