如何在我的地图 activity 顶部弹出一个 listView？

Question

我得到了基于 Google 地图 activity 的新应用程序。我将我的 onMapLongClickListener 设置为根据用户的需要添加尽可能多的新标记。但我有一个问题：我想在我的地图顶部设置一个 ListView，以允许用户在不同的标记类型之间进行选择。如何设置一个 ListView，它在我按住地图上的一个点时出现，然后在选择其中一项后消失？

这是我的应用程序代码，如果它可以帮助你提供一些解决方案！

MapsActivity.java

package com.example.mancu_000.onclickmarkerlistener;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.widget.Toast;

import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.GoogleMap.OnMapLongClickListener;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
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 MapsActivity extends FragmentActivity implements OnMapReadyCallback, OnMapLongClickListener {

    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        map = googleMap;

        map.setOnMapLongClickListener(this);
        map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {
                Toast.makeText(MapsActivity.this, "OnMarkerListener", Toast.LENGTH_SHORT).show();
                return true;
            }
        });

        LatLng home = new LatLng(44.42913, 8.84072);
        map.addMarker(new MarkerOptions().position(home).title("Home, bitches!"));
        map.moveCamera(CameraUpdateFactory.newLatLng(home));

        CameraUpdate center = CameraUpdateFactory.newLatLng(home);
        map.moveCamera(center);

        CameraUpdate zoom = CameraUpdateFactory.zoomTo(17);
        map.animateCamera(zoom);
    }

    @Override
    public void onMapLongClick(LatLng location) {
        // Here I'm supposed to implements thee code of the ListView on the top of the map
    }
}

activity_maps.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.mancu_000.onclickmarkerlistener.MapsActivity" >

    <fragment xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        class="com.google.android.gms.maps.SupportMapFragment"/>

</FrameLayout>

感谢您的支持！！

按下对话框获取标记列表，例如

@Override
    public void onMapLongClick(LatLng location) {
        AlertDialog.Builder builderSingle = new AlertDialog.Builder(context);
        builderSingle.setIcon(R.drawable.title_icon_resource);
        builderSingle.setTitle("Select One Name:-");

        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>();//create adapter with your markers list

        builderSingle.setNegativeButton();//to exit directly if you want

        builderSingle.setAdapter(arrayAdapter,new DialogInterface.OnClickListener());//set your adapter and listener
        builderSingle.show();
    }

希望对您有所帮助
