如何移动Android Google Maps API指南针位置

Question

有谁知道你是否可以改变地图内的指南针位置？

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

Answer 1

使用GoogleMap.setPadding()方法:

Answer 2

@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();
    }

}
