Android调用第三方地图

初学Android Studio之调用第三方地图

我们小组要做的app中要求可以调用第三方地图,比如百度、腾讯、谷歌。就自己在网上找的代码,修改得到的经验。

地图SDK

这个可以从百度地图上面下载,只要最后下载出来的有com.baidu.mapapi这个包就可以了。下载链接:
http://lbsyun.baidu.com/index.php?title=sdk/download&action#selected=mapsdk_basicmap,mapsdk_searchfunction,mapsdk_lbscloudsearch,mapsdk_calculationtool,mapsdk_radar

Android Studio具体的各部分我就不说了,很多人都有介绍。接下来就是代码啦,给自己码住!!

在这里要说一下,我之前的代码比如setContentView(R.layout.activity_main)中,R一直是红色的,说是找不到R文件,网上的方法大致都试了,没有用,最后发现是activity_main中的语法错误。
因为大佬用的Eclipce,和Android有点不同,有的语法是不一样的。
总之解决方法就是看Android下面执行栏里面的报错,这样的报错就会告诉你到底是哪个文件有问题。毕竟我的是MainActivity.java是红线报错,但实际出问题的是activity_main.xml
好啦!
