Question

我对点击地图标记时弹出的气泡有疑问。我搜索过互联网，但没有真正令人满意的答案。基本上我的问题是：如果没有我单击它，有没有办法让泡泡出现在默认值上？

我在下面的代码中显示了这一部分：

MarkerOptions tousgårdsladen = new MarkerOptions()
    .position(TOUSGÅRDSLADEN).title("Activity Name")
    .snippet("Snippet");"

如果单击标记，则会弹出一个带有“活动名称”文本的气泡，所以基本上我希望在没有单击的情况下加载标记时显示该气泡，如果单击它会为您提供有关活动的更多详细信息放置标记。

Answer 1

这很容易。使用以下代码：

Marker marker = myMap.addMarker(new MarkerOptions()
                 .position(latLng)
                 .title("Title")
                 .snippet("Snippet")
                 .icon(BitmapDescriptorFactory
                 .fromResource(R.drawable.marker)));

marker.showInfoWindow();
