java - 如何更改谷歌地图标记上方标题和 fragment 的设计

Question

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。但我不知道该怎么做。

解释；

我有这个:

我想要这个:

我有蓝色盒子的设计作为图像。但我不知道是否需要使用图像或编写代码使其看起来像图像。

这是我到目前为止的代码:

    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();

    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();

        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_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<TextView
    android:id="@+id/tv_location"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    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好的做法，请提前原谅。这些文件是我创建功能的 Playground ，以便我稍后可以将其放入实际应用程序中。

要更改信息窗口的外观(“位置标记上方的信息”)，您可以使用 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() 并返回用于给定 Marker 的 View。然后，您可以在 GoogleMap 上调用 setInfoWindowAdapter()，告诉它向您的 InfoWindowAdapter 请求要使用的 View用户点击标记。

This sample app演示了这个概念，但我重写了 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。你最终会得到这样的结果:
