界面非常简单如果想加入一些图片或者图标

可以添加到drawable里，然后调用图片即可

在开发过程中需要注意一下几点问题：（本人遇到问题较多）

1.build gradle中android里需要声明

sourceSets {

    main() {

        jniLibs.srcDirs = ['libs']

    }

}
否则会导致app闪退，点不开等情况
2.manife里一定要有以下声明 否则无法获取定位（本人使用百度地图api）

<!-- 声明service组件 -->
<service
    android:name="com.baidu.location.f"
    android:enabled="true"
    android:process=":remote" />
<!-- AK鉴权 -->
<meta-data
    android:name="com.baidu.lbsapi.API_KEY"
    android:value="2N8xydK1CHyShBGxYhMkzTP0jRsVv9Lh" /> <!-- http://lbsyun.baidu.com/apiconsole/key -->
标红字段需要自己去获取自己的ak ，官网有教学。
3.虚拟机定位点击后无法定位，是由于电脑没有gps定位，需要使用真机模拟，手动授权，然后即可定位。
下面附上我app的界面，后续我会完善app发至github。
