【问题描述】：

我目前正在开发一个涉及谷歌地图的应用程序。 我想更改位置标记上方信息的设计。但我无法弄清楚如何做到这一点。

解释一下；

我有这个：

我想要这个：

我将蓝色框的设计作为图像。但是我不知道我是否需要使用图像或编写代码使其看起来像图像。

这是我目前的代码：

MainActivity

import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;
import android.os.Build;
import android.os.Bundle;
import android.provider.Settings;
import android.support.v4.app.FragmentActivity;
import android.text.TextUtils;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;

import com.google.android.gms.location.LocationListener;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
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 MainActivity extends FragmentActivity implements     LocationListener 

    GoogleMap map;
    LatLng myPosition;

protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    isLocationEnabled(this);


    // Getting reference to the SupportMapFragment of activity_main.xml
    SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

    // Getting GoogleMap object from the fragment
    map = fm.getMap();

    // remove geolocation button
    map.getUiSettings().setMyLocationButtonEnabled(false);

    // Enabling MyLocation Layer of Google Map
    map.setMyLocationEnabled(true);

    // Getting LocationManager object from System Service LOCATION_SERVICE
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

    // Creating a criteria object to retrieve provider
    Criteria criteria = new Criteria();

    // Getting the name of the best provider
    String provider = locationManager.getBestProvider(criteria, true);

    // Getting Current Location
    Location location = locationManager.getLastKnownLocation(provider);

    if (location != null) 
        // Getting latitude of the current location
        double latitude = location.getLatitude();

        // Getting longitude of the current location
        double longitude = location.getLongitude();

        // Creating a LatLng object for the current location
        LatLng latLng = new LatLng(latitude, longitude);

        myPosition = new LatLng(latitude, longitude);
        LatLng amsterdam = new LatLng(52.3667, 4.9000);


        // create marker
        MarkerOptions marker = new MarkerOptions().position(myPosition);
        // setting custom marker
        marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.map_marker));

        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(myPosition);
        markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.map_marker));
        markerOptions.title(" Title");

        markerOptions.snippet(" Here comes the address ");


        // create and add marker
        Marker locationMarker = map.addMarker(markerOptions);
        // always show info text
        locationMarker.showInfoWindow();
        // opening maps zoomed in at current location
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(amsterdam, 17.0f));



    


@Override
public boolean onCreateOptionsMenu(Menu menu) 
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;


@Override
public boolean onOptionsItemSelected(MenuItem item) 
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) 
        return true;
    

    return super.onOptionsItemSelected(item);



@Override
public void onLocationChanged(Location location) 




public static boolean isLocationEnabled(Context context) 
    int locationMode = 0;
    String locationProviders;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) 
        try 
            locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);

         catch (Settings.SettingNotFoundException e) 
            e.printStackTrace();
        

        return locationMode != Settings.Secure.LOCATION_MODE_OFF;

     else 
        locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        return !TextUtils.isEmpty(locationProviders);
    


    

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
tools:context=".MainActivity">

<TextView
    android:id="@+id/tv_location"
    android:layout_
    android:layout_ />

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_
    android:layout_
    android:layout_below="@id/tv_location"
    class="com.google.android.gms.maps.SupportMapFragment"
    tools:layout="@layout/abc_action_bar_title_item" />


</RelativeLayout>

如果我使用了草率的编码或不良做法，请提前原谅。这些文件是我创建功能的游乐场，以便我以后可以将其放入实际的应用程序中。

【参考方案1】：

要更改信息窗口的外观（“位置标记上方的信息”），请使用InfoWindowAdapter。在您的情况下，您想要替换整个窗口，包括内容和框架（带有指向标记的插入符号的东西）。因此，您的InfoWindowAdapter 将实现getInfoWindow() 并返回View 以用于给定的Marker。然后你在你的GoogleMap 上调用setInfoWindowAdapter()，告诉它在用户点击Marker 时向你的InfoWindowAdapter 询问View。

This sample app 演示了这个概念，尽管我覆盖了getInfoContents() 而不是getInfoWindow()，因为我想替换内容但使用现有的信息窗口框架。你会得到这样的结果：
