如何在android中用标记显示地图

我正在开发 Android 应用程序，而且我在这方面完全是新手。所以我想知道如何在地图中显示标记以及如何在特定时间更改他的位置，例如定义线程或背景中的任何内容，这些内容将发送纬度和经度值并且标记在该位置上移动

如果您只想展示单个项目，MapView.addView()然后更新位置setLayoutParams就可以了。

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);
    }
}
