android 百度地图marker点添加 删除 动画

LatLng point = new LatLng(markx,marky);//坐标参数（纬度，经度）BitmapDescriptor bitmap = BitmapDescriptorFactory.fromResource(R.mipmap.drone);//自定义marker点图片

//构建MarkerOption，用于在地图上添加MarkerOverlayOptions option = new MarkerOptions().position(point).icon(bitmap);

marker = (Marker) map.addOverlay(option);//将marker添加到地图，并获取该marker点对象

marker.remove();//删除

AlphaAnimation animation = new AlphaAnimation(1.0f,0.0f);//marker点动画（需导入百度地图的Animation包）animation.setDuration(3000);marker.setAnimation(animation);marker.startAnimation();

OverlayOptions ooCircle = new CircleOptions().fillColor(R.color.colorAccent)//地图上已point为中心添加圆.center(point).stroke(new Stroke(5, R.color.colorPrimary)).radius(1400);
