android - 可以用地图 v2 创建一个透明的信息窗口吗？

Question

Hieveryone，一个问题。我像这样应用infowindows的背景：

android:background="#55000000"

但是它背后似乎总是有一个白色背景，有没有可能摆脱它？谢谢！

实现您自己的 InfoWindowAdapter 用于自定义设计 infoWindow

示例代码

    private final View mWindow;

    public MarkerAdapter() {
        mWindow = getLayoutInflater().inflate(R.layout.custom_info_window,
                null);
    }

    @Override
    public View getInfoContents(Marker mark) {

        return null;
    }

    @Override
    public View getInfoWindow(Marker marker) {

        render(marker, mWindow);
        return mWindow;
    }

    private void render(Marker marker, View view) {
        int badge;
        // Use the equals() method on a Marker to check for equals. Do not
        // use ==.
        badge = R.drawable.ic_launcher;

        ((ImageView) view.findViewById(R.id.badge)).setImageResource(badge);

        String title = marker.getTitle();
        TextView titleUi = ((TextView) view.findViewById(R.id.title));

        titleUi.setText(title);

        String snippet = marker.getSnippet();
        TextView snippetUi = ((TextView) view.findViewById(R.id.snippet));

        snippetUi.setText(snippet);

    }

}

然后将其称为

mMap.setInfoWindowAdapter(new MarkerAdapter());
