android开发之百度地图marker点添加,删除,动画等操作实例
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Marker OverlayOptions 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);
