如何移动Android Google Maps API指南针位置

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

有谁知道你是否可以改变地图内的指南针位置?

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.

我能找到的是如何启用或禁用它。但是我需要将它向下移动一点,这样我的叠加层就不会妨碍它。

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.

据我所知,你不能改变指南针的位置,但你可以禁用它并建立你的私人指南针。

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 :

我知道这个问题已经问了很长时间了,但是几天前我对这个问题感到厌烦,我解决了这个问题:

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.

在这个例子中,我将指南针放在右角。您需要确保在执行此操作时创建了mapFragment,我建议您在MapFragment的方法“onMapReady”中运行代码。

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:

基于填充的解决方案适用于小偏移,但据我所知,没有暴露的API允许我们像Google Maps应用程序那样从左到右稳健地改变指南针的水平“重力”:

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.

请注意,如果您在自己的应用中应用了大量的左边距以将指南针向右移动,则左下角的Google徽标也会向右移动。

On 2.0 map api.

在2.0地图api上。

        // 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
    }
