百度地图实现与总结..

因为公司用到百度地图比较多，所以就自己给自己总结总结：

想要使用百度地图， 1. 你要先注册1个百度账号（到时候申请key需要）

2. 需要百度的SDK

1.2都很简单，可以自行解决了。--- 说实话 官网上的 demo 真心也很详细呢 = = 网址：http://developer.baidu.com/map/sdkandev-6.htm#.E7.AE.80.E4.BB.8B4

现在看下工程

把 需要的东西全部放进工程。

然后就开始看代码吧（---部分代码哦---）。

自定义图层

1. /*
2. *要处理overlay点击事件时需要继承ItemizedOverlay
3. *不处理点击事件时可直接生成ItemizedOverlay.
4. */
5. classOverlayTestextendsItemizedOverlay<OverlayItem>{
6. //用MapView构造ItemizedOverlay
7. publicOverlayTest(Drawablemark,MapViewmapView){
8. super(mark,mapView);
9. }
10. protectedbooleanonTap(intindex){
11. //在此处理item点击事件
12. System.out.println("itemonTap:"+index);
13. returntrue;
14. }
15. publicbooleanonTap(GeoPointpt,MapViewmapView){
16. //在此处理MapView的点击事件，当返回true时
17. super.onTap(pt,mapView);
18. returnfalse;
19. }

因为 直接很多的例子很多，所以我就结合自己部分应用的代码直接贴出来了。想要更详细的了解还是要看，文章的开头 百度地图官网，例子注释狠详细。

下面拿过来的

配置Activity：

横竖屏切换后Activity会重新执行onCreat函数，但是在Android工程的Mainfest.xml中加入android:screenOrientation="user" android:configChanges="orientation|keyboardHidden"之后，横竖屏切换之后就不会去执行OnCreat函数了，而是会去调用onConfigurationChanged()，这样我们就能控制横竖屏的切换了。

添加屏幕及版本支持：

第三步：在布局xml文件中添加地图控件，布局文件保存为activity_main.xml：
