如何设置动画到中心贴图的其他位置
原标题:How to animate to other position that center map

我有一个扩展MapActivity的活动,在onCreate()中我有以下代码

 GeoPoint point = new GeoPoint((int)(1.3*1E6),(int)(34.45*1E6)); 
 final MapController mc;
 mc.animateTo(point);

但是,当它设置动画时,该点位于屏幕的中心,我希望它位于屏幕上的固定(X,Y)位置。是否存在mc.animatetoLeftBottom(点)函数?

Edit : I used the Projection p = mapView.getProjection(); point = p.fromPixels(50, 60); mc.animateTo(point);

pictures: When I start the app, it looks like this :

我敲了一下针,它看起来是这样的

而且,如果我再次点击大头针,它会是这样的:

这就是它的外观,无论我从哪里点击它,或者如果我滚动、缩放然后再次点击:

我想要的是当我点击引脚时,它自动移动到那个位置(见最后一张图片)

最佳回答

难道你不能改变<code>GeoPoint</code>来说明事实,并动画到另一个点吗?

问题回答

试试这个:

MapView mv = getMapView(); // fetch your map view
Projection p = mv.getProjection(); 
GeoPoint point = p.fromPixels(X, Y);
mc.animateTo(point);
