本文展示了如何在Android应用中使用高德地图API进行路线规划。首先，添加必要的权限如互联网访问、读写外部存储等。接着，配置API Key以启用地图服务。然后，详细介绍了如何创建Activity并实现各种路线（公交、驾车、步行）的搜索功能，包括监听器设置、起点和终点的选择、以及不同模式的切换。此外，还提供了地理编码、路径搜索和展示等关键步骤。

添加权限：

<uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <uses-permission android:name="android.permission.WRITE_SETTINGS" />

添加Key
