（电商中需要定位需求）百度地图定位sdk集成，及城市列表展示，选择，搜索，26字母快速定位
下面集成步骤：
主要还是依靠百度定位文档一步一步
1，先去百度开发者平台，创建你的应用，
根据你的sha1和包名获取app在百度定位中的AK
如下图：
添加SDK（jar + so）
下载Android定位SDK并解压，将libs中的jar和so放置到工程中相应的位置。
注意，Android定位SDK提供了多种CPU架构的so文件（jar通用，只有一个），开发者可根据实际使用需求，放置所需so到对应的工程文件夹内。
，配置build.gradle文件
配置build.gradle文件，注意设置sourceSets。
sourceSets{
main{
jniLibs.srcDir ‘libs’
jni.srcDirs = [] //disable automatic ndk-build
}
}
然后带上你的AK去你的manifest中注册应用
，添加定位权限
使用定位SDK，需在AndroidManifest.xml文件中Application标签中声明service组件，每个App拥有自己单独的定位service，代码如下：
除添加service组件外，使用定位SDK还需添加如下权限：
看不懂可进入[百度定位sdk，studio配置]看文档
下面代码中可直接定位：
在哪里定位 直接调用即可：
/**定位**/
BDLocationUtils.instance.startLocation(this, object : BDLocationUtils.ResultCallback {
override fun fail() {
location.text = (resources.getText(R.string.location_default))
BDLocationUtils.instance.stopLocation()
showSelectAddrDialog()
}
override fun onPermissionError() {
location.text = (resources.getText(R.string.location_default))
BDLocationUtils.instance.stopLocation()
showSelectAddrDialog()
}
override fun success(city: String) {
var addr = ""
if (city.isEmpty()) {
location.text = (resources.getText(R.string.location_default))
showSelectAddrDialog()
} else {
if (city.contains("市")) {
addr = city.substringBefore("市", city)
}
location?.text = if (addr.length > 2) addr.substring(0, 2) + "..." else addr
BDLocationUtils.instance.stopLocation()
hideSelectAddrDialog()
}
}
})
