android高德地图根据经纬度添加标注(Marker)

onCreate方法中添加 :

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mapView.onCreate(savedInstanceState);//mapView为高德地图 MapView
        //AMap是地图对象
        aMap = mapView.getMap();//得到AMap对象 latitude 维度 longitude 精度 经纬度设置成自己的经纬度即可
        CameraPosition cameraPosition = new CameraPosition(new LatLng(this.latitude, this.longitude), 15, 0, 30);
        CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
        aMap.moveCamera(cameraUpdate);
     //添加标注 addMarkers(); }

添加标注(marker)

/**
     * 添加标注
     */
    private void addMarkers() {
        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.anchor(1.3f, 1.5f);//点标记的锚点
        Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
                R.mipmap.icon_map_add);
        markerOptions.icon(BitmapDescriptorFactory
                .fromBitmap(bitmap));
        markerOptions.position(new LatLng(latitude, longitude));
        Marker growMarker = aMap.addMarker(markerOptions);
        growMarker.setClickable(true); //marker 设置是否可点击
        startGrowAnimation(growMarker);
        growMarker.showInfoWindow();
    }

添加标注的生长动画效果:

 private void startGrowAnimation(Marker marker) {

        if (marker != null) {
            Animation animation = new ScaleAnimation(0, 1, 0, 1);
            animation.setInterpolator(new LinearInterpolator());
            //整个移动所需要的时间
            animation.setDuration(1000);
            animation.setFillMode(1);//动画保存之前的状态为1 之后为0
            //设置动画
            marker.setAnimation(animation);
            //开始动画
            marker.startAnimation();
            marker.showInfoWindow();
        }
    }

最后onDestyoy销毁:

  @Override
    protected void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }
