我用谷歌地图 Java普朗普朗文V3显示一个定期的googlemap和一个街口。 当地图的位置发生变化时,它用“街日”号(Panorama.setPosition)来说明街道情况。
然而,当我把地图绘制到没有街道口号的地方时,街道观图像在最后地点停留。 它的“政治”方法与主地图相同。
我怎么能告诉我,我是否已经迁到街区。 观点是没有的?

我找到了答案,如果不是。
每一次移动后,使用街电学服务,在N meters内获得最接近的帕诺马。 根据这一规定,你可以停留在你身处、移动或固定地点。
我使用旗帜和固定时间来防止许多不必要电话进入Panorama。 类似情况:
var check_availability_lock = false;
var check_availability = function() {
if (check_availability_lock) {
return;
}
check_availability_lock = true;
var availability_cb = function(data, status) {
check_availability_lock = false;
// console.log("status = ", status);
if (status !== OK ) {
map.setVisible(false);
}
else {
map.setVisible(true);
}
}
setTimeout(function(){
var latlng = map.getPosition();
svc.getPanoramaByLocation(latlng, 50, availability_cb);
}, 2000);
};
