单击标记时打开不同的活动（多个标记）

Question

当我点击标记时，我想打开地图的新活动。我已经创建了多个标记，但在这段代码中，我只是从中获取了标题名称。

例如，有 7 个标记位置，如果我按下任何标记，则会打开新活动并且应该有一些数据，因此如果我单击另一个标记，则会打开另一个活动，其中包含一些内容。

但它应该会打开并显示有关该位置的一些详细信息。您可以只指导我完成两项活动，之后我将能够完成其余的工作。

在您的地图 OnMarkerClickListerner 上，只需检查您的标记位置是否与您的地点位置匹配

            mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
                @Override
                public boolean onMarkerClick(Marker marker) {
                    String markertitle= marker.getTitle();
                    if (marker.getPosition() == Tasmorth){
                        //launch activity here
                    }
                    return false;
                }
            });

您应该将标记存储到列表中以便于比较位置。
