推荐答案
The method GoogleMap.addMarker() returns the Marker, which was added. Save your Markers to a List.
List<Marker> list = new ArrayList<Marker>();
for(int i = 0; i < Lat.length; i++)
{
Marker marker = map.addMarker(new MarkerOptions()
.position(new LatLng(Lat[i], Lon[i]))
.title(Market[i])
.snippet(Address[i])
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
list.add(marker);
}
现在搜索适合您条件的标记(此处为摘录).
Now search for the Marker, which fits your condition (here the snippet).
for(Marker m : list) {
if(m.getSnippet().equals(yourSnippet)) {
// do something with the marker
break; // stop the loop
}
}
提示:请勿将纬度和经度值保存在单独的数组中.使用 LatLng 类存储它们，这样可以更好地维护.
As a hint: don't save your latitude and longitude values in separate Arrays. Use the LatLng class to store them, which is better to maintain.
要从SearchView中获取文本，可以使用getText()方法.让 onKeyListener 可以在用户按下所需的事件时捕获事件键，然后从SearchView中获取文本.
To get the text from the SearchView you can use the getText() method. Have a onKeyListener to grab the event when the user presses the desired key and get the text from the SearchView.
或者更好的选择是设置 SearchView.OnQueryTextListener 和在onQueryTextSubmit()回调中获取文本.
Or the better alternative set a SearchView.OnQueryTextListener and get the text in the onQueryTextSubmit() callback.
