// 可能是由于官方文档没有写让用户传入经纬度，尝试传入经纬度之后，打开手机的调试模式，可以获取到屏幕的x,y点 
mapContext.toScreenLocation({           
  latitude,           
  longitude,           
  success(res){             
     console.log("res",res)           
  }         
})

着急的话自己写吧，哈哈：

this.mapCtx.getRegion({
            success: (res) => {
                        const screenSw = res.southwest;
                        const screenNe = res.northeast;
                        const screenHeight = wx.getSystemInfoSync().windowHeight;
                        const screenWidth = wx.getSystemInfoSync().windowWidth;
                        var point = {
                            latitude: 24.080332,
                            longitude: 98.069048
                        }
                       var x= screenWidth / (screenNe.longitude - screenSw.longitude) * (point.longitude-screenSw.longitude)
                       var y= screenHeight / (screenSw.latitude - screenNe.latitude) * (point.latitude-screenNe.latitude)
                        console.log('x坐标',x,y);
                    },
            fail: (err) => {
                console.log('失败', err);
            }
        })

你好，先参考下文档接入下看看：https://developers.weixin.qq.com/miniprogram/dev/api/media/map/MapContext.toScreenLocation.html。
