安卓调用百度地图实现

本文将讲述安卓调用百度地图的实现方法,刚接触百度地图的童鞋可以作为参考,先看效果图:


 

 

再看工程文件:

注意,该项目所用百度sdk为最新版,需用最新密钥,再次声明,那些在调用百度地图时老是不正常的童鞋,一定要根据你的sdk版本申请对应密钥,这个我已经在上一篇文章中讲过了,大家可以去参考下。

首先看,主界面布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

                android:text="搜索"
                android:textSize="18sp" />

            <ImageView

        </RelativeLayout>

            }
        }
    }
}


当然,不要忘了在清单文件中配置aplication:

<application
        android:name="com.byl.testbaidumap.MyApplication"

还有调用百度地图相关的权限都已在清单文件中写的很清楚,以及代码中注释也比较详细,大家可以下载我的源码作为参考:
