android - 搜索 Android map 标记标题和 fragment

Question

我有一张带有多个标记的 map ，我希望能够通过标记标题或 fragment 来搜索它们。我是 Android 的新手，所以我不完全确定如何去做。任何指向我正确方向的帮助都会很棒。

这是我的代码:

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);

      Double[] Lat = {

Answer 1

方法GoogleMap.addMarker()返回添加的标记。将您的标记保存到列表中。

  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);
  }

现在搜索符合您条件的标记(此处为代码段)。

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

提示:不要将纬度和经度值保存在单独的数组中。使用 LatLng类来存储它们，这样更好维护。

编辑:

要从 SearchView 获取文本，您可以使用 getText() 方法。有一个onKeyListener当用户按下所需的键并从 SearchView 获取文本时获取事件。

或者更好的选择设置一个 SearchView.OnQueryTextListener并在 onQueryTextSubmit() 回调中获取文本。
