How to move the Android Google Maps API Compass Position

问题

Does anyone know if you can change the compass position within the map?

All I can find is how to enable or disable it. But I need to move it down a bit so my overlay is not obstructing it.

回答1:

Use GoogleMap.setPadding() method:

@Override
public void onMapReady(GoogleMap map) {

    try {
        final ViewGroup parent = (ViewGroup) mMapView.findViewWithTag("GoogleMapMyLocationButton").getParent();
        parent.post(new Runnable() {
            @Override
            public void run() {
                try {
                    Resources r = getResources();
                    //convert our dp margin into pixels
                    int marginPixels = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 20, r.getDisplayMetrics());
                    // Get the map compass view
                    View mapCompass = parent.getChildAt(4);

                    // create layoutParams, giving it our wanted width and height(important, by default the width is "match parent")
                    RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(mapCompass.getHeight(),mapCompass.getHeight());
                    // position on top right
                    rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0);
                    rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
                    rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
                    rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0);
                    //give compass margin
                    rlp.setMargins(marginPixels, marginPixels, marginPixels, marginPixels);
                    mapCompass.setLayoutParams(rlp);
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        });
    } catch (Exception ex) {
        ex.printStackTrace();
    }

}

As I know you can't change compass position but you can disable it and build yours private one.

See example here

I know it's been a long time that the question was asked , but I feld on this issue a few days ago I fixed the problem like this :

try {
                assert mapFragment.getView() != null;
                final ViewGroup parent = (ViewGroup) mapFragment.getView().findViewWithTag("GoogleMapMyLocationButton").getParent();
                parent.post(new Runnable() {
                    @Override
                    public void run() {
                        try {
                            for (int i = 0, n = parent.getChildCount(); i < n; i++) {
                                View view = parent.getChildAt(i);
                                RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) view.getLayoutParams();
                                // position on right bottom
                                rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0);
                                rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP,0);
                                rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
                                rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                                rlp.rightMargin = rlp.leftMargin;
                                rlp.bottomMargin = 25;
                                view.requestLayout();
                            }
                        } catch (Exception ex) {
                            ex.printStackTrace();
                        }
                    }
                });
            } catch (Exception ex) {
                ex.printStackTrace();
            }

in this exemple i put the compass in the corner right. You need to be sure that your mapFragment is created when you do this, i suggest you run your code in the method "onMapReady" of your MapFragment.

On 2.0 map api.

        // change compass position 
    if (mapView != null &&
            mapView.findViewById(Integer.parseInt("1")) != null) {
        // Get the view
        View locationCompass = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("5"));
        // and next place it, on bottom right (as Google Maps app)
        RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
                locationCompass.getLayoutParams();
        // position on right bottom
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
        layoutParams.setMargins(0, 160,30, 0); // 160 la truc y , 30 la  truc x
    }

Padding-based solutions work for small offsets, but as far as I know there's no API exposed that allows us to robustly change the horizontal "gravity" of the compass from left to right like the stock Google Maps app does:

Note that if you applied a large amount of left padding to move the compass to the right in your own app, the Google logo in the bottom left would also be shifted over to the right.
