如何通过标记标题关注Google标记？ [英] how to focus google marker by marker title?

问题描述

我想通过给予标题来关注标记，现在我正在使用lat和lng进行关注。

i want to focus on marker by giving title right now i am focusing by using lat and lng

mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(26.89454, 75.82607), 15.0f));

因此，无论如何，我都可以通过标记的标题名称专注于特定标记。

So is there anyway i could focus on particular marker by Title name of the marker

推荐答案

您可以将标记存储在 Map< String Marker> key：

You can store your markers in a Map<String Marker> using the title as the key:

private Map<String, Marker> markers = new HashMap<>();

当您将标记添加到地图时，还需要将它们添加到散列贴图：

When you add your markers to the map, you need to also add them to the hashmap:

String markerTitle = "My Marker";
LatLng markerPosition = new LatLng(26.89454, 75.82607);
Marker marker = mMap.addMarker(new MarkerOptions().position(markerPosition).title(markerTitle));
markers.put(markerTitle, marker); // Add the marker to the hashmap using it's title as the key

然后您可以将标记查询居中HashMap：

Then you can center your marker querying the hashmap:

private void centerMarker(String title) {
    Marker marker = markers.get(title);
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(marker.getPosition(), 15f));
}
