MapView Marker shadow坐标问题

Drawable drawable = app1.getResources().getDrawable(R.drawable.test); 
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight()); 
OverlayItem overlayitem2 = new OverlayItem(mark, "Test", "t"); 
overlayitem2.setMarker(drawable); 
app1.mapOverlay.addOverlay(overlayitem2); 
app1.mapOverlays.add(app1.mapOverlay); 如果你想使用阴影 一定要注意坐标 将drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight()); 
改为：int w = drawable.getIntrinsicWidth(); 
int h = drawable.getIntrinsicHeight(); 
drawable.setBounds(-w / 2, -h, w / 2, 0);
