Поиск в Android-маркере Заголовки и фрагменты маркера

Question

У меня есть карта с несколькими маркерами, и я хотел бы иметь возможность искать их по названию маркера или фрагменту. Я новичок в Android, поэтому я не совсем уверен, как это сделать. Любая помощь, указывающая мне в правильном направлении, была бы замечательной.

Вот мой код:

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 

import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.GoogleMap.OnInfoWindowClickListener; 
import com.google.android.gms.maps.MapFragment; 
import com.google.android.gms.maps.model.BitmapDescriptorFactory; 
import com.google.android.gms.maps.model.LatLng; 
import com.google.android.gms.maps.model.Marker; 
import com.google.android.gms.maps.model.MarkerOptions; 

public class RSFM extends Activity 
{ 
    static final LatLng KENTUCKY = new LatLng(37.833333, -85.833333); 
    private GoogleMap map; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_rsfm); 
     map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 
     map.moveCamera(CameraUpdateFactory.newLatLngZoom(KENTUCKY, 15)); 

     // Zoom in, animating the camera. 
     map.animateCamera(CameraUpdateFactory.zoomTo(7), 2000, null); 

     // Enable the My Location Layer 
     map.setMyLocationEnabled(true);

Answer 1

Метод GoogleMap.addMarker() возвращает маркер, который был добавлен. Сохраните маркеры в списке.

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); 
    } 

Теперь найдите маркер, который соответствует вашему состоянию (здесь фрагмент).

for(Marker m : list) { 
    if(m.getSnippet().equals(yourSnippet)) { 
     // do something with the marker 
     break; // stop the loop 
    } 
} 

В качестве подсказки: не сохраняйте значения широты и долготы в отдельных массивах. Используйте класс LatLng для их хранения, который лучше поддерживать.

Edit:

Чтобы получить текст из SearchView вы можете использовать метод GetText(). Имейте onKeyListener, чтобы захватить событие, когда пользователь нажимает нужный ключ и получает текст из SearchView.

Или лучше альтернативный набор SearchView.OnQueryTextListener и получить текст в обратном вызове onQueryTextSubmit().
