推荐答案

如果你要只显示一个单一的项目， MapView.addView（）后来更新与 setLayoutParams 位置是卓有成效的。

If you're going to show just a single item, MapView.addView() and later updating position with setLayoutParams does the trick.

private ImageView mCurrentPointer;

@Override
public void onLocationChanged(Location l) {
    int latitude = (int) (l.getLatitude() * 1e6);
    int longitude = (int) (l.getLongitude() * 1e6);
    // Prepare new LayoutParams object that centers on our new latitude/longitude
    MapView.LayoutParams lp = new MapView.LayoutParams(MapView.LayoutParams.WRAP_CONTENT, 
            MapView.LayoutParams.WRAP_CONTENT, new GeoPoint(latitude, longitude),
            MapView.LayoutParams.CENTER);

    if (mCurrentPointer == null) {
        // If "current location" pin is null, we haven't added it
        // to MapView yet. So instantiate it and add it to MapView:
        mCurrentPointer = new ImageView(this); 
        mCurrentPointer.setImageResource(R.drawable.ic_maps_indicator_current_position);
        mMapView.addView(mCurrentPointer, lp);
    } else {
        // If it's already added, just update its location
        mCurrentPointer.setLayoutParams(lp);
    }
}
