Android地图SDK | 百度地图API SDK
【Android】实现百度地图显示_宾有为的博客-CSDN博客 本人使用的是aar开发包ros-mobile工程中app下没有libs文件夹需要新建。把开发包libs下的文件复制到工程中的libs。在app下的build.gradle中添加了如下代码。
implementation files(libs/BaiduLBS_Android.aar) // 添加这一行替换为你的 AAR 文件名
查阅资料了解到百度地图SDK初始化在程序入口进行较好可以避免多次初始化或冲突问题。
MainActivity.java中添加 protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main); //置当前活动使用的布局文件为 activity_main.xml// 同意百度地图的隐私政策SDKInitializer.setAgreePrivacy(getApplicationContext(), true);// 初始化百度地图 SDKSDKInitializer.initialize(getApplicationContext());SDKInitializer.setCoordType(CoordType.BD09LL);try {
......//其他代码
对应.xml文件 !-- 百度地图组件 --com.baidu.mapapi.map.MapViewandroid:idid/baiduMapViewandroid:layout_widthmatch_parentandroid:layout_height0dpandroid:layout_weight1android:visibilityvisible / 对应fragment.java文件

}最终效果 增加定位功能
第一版本可以显示定位蓝点但是定位有误差偏差几个街道此方法不稳定第二次进入该标签页测试时会出现定位点无法显示的情况

}按照百度地图提供的关于定位教程无法实现定位功能初始化客户端的时候总是报错按照提示使用try会出现闪退无法显示地图网上也有看到相同错误但是没找到解决适用的方法。有解决该问题的欢迎交流
// 初始化客户端mLocationClient new LocationClient(requireContext());
