微信小程序地图动态加载marker出现闪烁现象

框架类型 问题类型 操作系统 工具版本
小程序 Bug Windows V1.02.1812271

- 当前 Bug 的表现(附上截图)

可以看到拖动地图出现明显的闪烁。


使用微信小程序地图动态展示marker,当用户拖拽或缩放地图时需要加载当前区域内的marker,但是使用setData({markers:markers})出现很明显的闪烁现象,该怎么解决?

- 预期表现

移动地图,动态加载marker,地图上的marker无明显闪烁现象,让用户感觉不到marker刷新了。或者能否提供插入或删除单个marker的方法,这种批量操作marker的效率太低了。

- 复现路径

用鼠标拖动地图,marker重新加载会出现闪烁

- 复现 Demo


demo如下:

map.wxml:

<view class="map_container">
 
<map class="map" id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="14" show-location="true" markers="{{markers}}" bindregionchange="regionchange"></map>
 
</view>

map.wxss:

.map_container{
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}
.map{
  width: 100%;
  height: 100%;
}

map.js

var amapFile = require('../../libs/amap-wx.js');
var markersData = [];
Page({
  data: {
    markers: [],
    latitude: '32.864377803922',
    longitude: '115.788491268263'
  },
  onLoad: function () {
    var that = this;
  },
  onShow:function(){
    //模拟从服务器加载设备
    //模拟网络延迟
    setTimeout(() => {
      var markers = this.getMarkers();
      this.setData({
        markers: markers
      });
    }, 1000);
  },
  regionchange:function(res){
    if(res.type=='end'){
      console.log("加载设备");
      //模拟从服务器加载设备
      //模拟网络延迟
      setTimeout(()=>{
        var markers = this.getMarkers();
        this.setData({
          markers: markers
        });
      },1000);
    }
  },

    我也遇到这个问题。动态更新某个marker的ui(边框/背景颜色),闪烁特厉害,效果完全不能直视。

    模拟器上倒没问题一点不闪烁。

    拖拽/缩放时候marker都正常。

    感觉像是setdata(marker..操作内部先清零一遍mark刷新一次,然后再添加所有mark再刷新导致的。明显逻辑有问题啊。

    这部分lib代码是刚毕业的程序员写的么?
