android---高德地图（5）导航界面（语音播报）实现

配置工程：实现语音播报的功能需要到科大讯飞官网下载相应的sdk，目前使用到的是语音合成功能（将文本内容转换成语音）
将对应的配置文件复制保存到Libs目录下。添加相应的权限和appkey

<meta-data
            android:name="IFLYTEK_APPKEY"
            android:value="'54be2ada'" />
        <meta-data
            android:name="IFLYTEK_CHANNEL"
            android:value="Android_Demo" />

 
 布局文件里面添加这个控件(显示导航界面)

<com.amap.api.navi.AMapNaviView 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/>
