Question

我想访问我在getMyLocationAddress中的onLocationChanged方法中的当前位置来设置文本框的文本。我想知道哪个变量是我的位置确切存储，以便我可以在geocoder.getLocationFrom（）中使用它。

我在geocoder.getFromLocation（latLng.getLatitude（），latLng.getLongitude（），1）中使用LatLng对象latLng; 这是我猜的当前位置存储。但getFromLocation需要Location对象。我应该使用哪个Location对象作为LatLng对象显然会出错？

@Override
    public void onLocationChanged(Location location) {

        mLastLocation = location;
        if (mCurrLocationMarker != null) {
            mCurrLocationMarker.remove();
        }

        //Place current location marker
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(latLng);
        markerOptions.title("Current Position");
        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE));
        mCurrLocationMarker = mMap.addMarker(markerOptions);

        //move map camera
        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
        mMap.animateCamera(CameraUpdateFactory.zoomTo(50));

        //stop location updates
        if (mGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
        }

    }


 public void getMyLocationAddress() {

    Geocoder geocoder= new Geocoder(this, Locale.ENGLISH);

    try {

        //Place your latitude and longitude
       //List<Address> addresses = geocoder.getFromLocation(37.423247,-122.085469, 1);
        List<Address> addresses = geocoder.getFromLocation(latLng.getLatitude(),latLng.getLongitude(),1);

        if(addresses != null) {

            Address fetchedAddress = addresses.get(0);
            StringBuilder strAddress = new StringBuilder();

            for(int i=0; i<fetchedAddress.getMaxAddressLineIndex(); i++) {
                strAddress.append(fetchedAddress.getAddressLine(i)).append("\n");
            }

            etOrigin.setText(strAddress.toString());

        }

        else
            etOrigin.setText("No location found..!");

    }
    catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Toast.makeText(getApplicationContext(),"Could not get address..!", Toast.LENGTH_LONG).show();
    }
}

您需要使用位置类型的变量。
