以下是 继承自arcgis js api 中TiledMapServiceLayer的  google 切片地图定义代码：//定义 google 图层
function defineClassesBeforInitMap() {
    dojo.declare("GoogleMapLayer", esri.layers.TiledMapServiceLayer, {
        constructor: function () {

            this.fullExtent = new esri.geometry.Extent(-20037508.342787, -20037508.342787, 20037508.342787, 20037508.342787, this.spatialReference);
            this.initialExtent = new esri.geometry.Extent(11501488.165446503, 3695866.152885527, 11678516.32295504, 3728734.075048165, this.spatialReference);

Answer 2

我觉得有可能是坐标系兼容问题，我的也是类似问题，百度地图，Google地图，本地地图三者加载顺序不一样，可以正常显示地图的情况不一样
