1. 新建项目

osmdroid在线：

（1）添加依赖

（2）布局文件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.MapViewandroid:id="@+id/mapView"android:layout_width="match_parent"android:layout_height="match_parent"/><Buttonandroid: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>
