Android 利用OSMdroid开发GIS 添加 控件以及定位

部署看这个：Android 利用OSMdroid开发GIS-CSDN博客

添加控件，直接上源码

activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<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"
    android:orientation="vertical">

   <org.osmdroid.views.MapView
       android:id="@+id/mapView"
       android:layout_width="match_parent"
       android:layout_height="match_parent"/>

   <Button
       android:id="@+id/btnLocation"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="定位"
       android:layout_margin="10dp"
       android:layout_alignParentTop="true"/>

</RelativeLayout>
