java Android |将导航抽屉添加到默认地图活动

Question

我已经寻找这个问题的答案好几个星期了，所以如果我看起来有点沮丧，请原谅。因为我是

事先，如果之前有人问过这个问题，我很抱歉。我不熟悉Android编程（我主要做网络应用），这对我来说是一个全新的世界。感谢您的帮助

我想做的是将导航抽屉添加到标准的常规地图活动中。我该怎么做呢？我希望每个按钮都能将地图重新居中到另一个地方

当我们在做的时候，我计划在我的地图上创建一个KML图层。正如你所知，KML积分中内置了信息，因此当你点击/点击它们时，你可以看到信息。我想让KML point打开带有内置信息的导航抽屉。我可以使用默认的安卓点数来实现这一点，但KML的一些功能是值得赞赏的。如果您想要一个参考框架，可以考虑以下JavaScript示例，但侧栏大部分时间是隐藏的：https://developers.google.com/maps/documentation/javascript/kml

如果您想在地图活动上方导航，请更新活动\u main。xml

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout"
        android:layout_width="match_parent" android:layout_height="match_parent"
        android:fitsSystemWindows="true" tools:openDrawer="start">

        <fragment 
          android:id="@+id/map"
           android:name="com.google.android.gms.maps.SupportMapFragment"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
  tools:context="us.tourismproject.jared.tourismprojectandroid.MainActivity" />

        <android.support.design.widget.NavigationView android:id="@+id/nav_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:fitsSystemWindows="true">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">

                <!  Draw your view whatever you want to draw  >

            </LinearLayout>


        </android.support.design.widget.NavigationView>

    </android.support.v4.widget.DrawerLayout>

它将创建您的导航抽屉正如rajan提到的一个答案，您需要编写一些代码来处理导航抽屉
