Android - 百度导航Demo,我们一起来踩坑!

Kotlin - 百度导航Demo,我们一起来踩坑!

背景

项目开发中,我们总是离不开定位、地图这些功能,当然有时候有了地图,那么导航就显得很有必要了。现在让我们开启百度导航吧!

第一步:磨刀不误砍柴工,获得你需要的SDK包

下载地址:百度LBS导航SDK

首先我们得从官网采集我们需要的百度LBS开发包,此处就暂时省略啦!

*注意:要使用百度TTS语音,我们需要注册百度导航TTS白名单,否则我们的导航器可是不会吭声的哦!(当然,你自己集成了其他TTS库除外)

第二步:不积洼步,不足以至千里。学习他人经验,事半功倍

配置说明:百度LBS配置

SDK均已按照官方配置好了,现在我们需要做得就是看别人怎么写的 -- 查看官方导航DEMO源代码。

从官方Demo中可以看出,导航流程大致如下:

初始化SDK ---> 初始化导航配置参数 ---> 规划导航路线 -->开始导航

因此我们可以把官方导航Demo修改一下,直接拿来用!

下面是我总结的一个工具类,仅供参考:

class BaiduMapNavigator private constructor(val activity: Activity) {

    companion object {

        @JvmField
        val ROUTE_PLAN_NODE = "routePlanNode"

        @JvmField
        var isBaiduNaviInitSuccess: Boolean = false

        @SuppressLint("StaticFieldLeak")
        @JvmField
        var baiduNavi: BaiduMapNavigator? = null

        @JvmStatic
        fun getInstance(context: Activity): BaiduMapNavigator? {
            if (baiduNavi == null) {
                synchronized(BaiduMapNavigator::class.java) {
                    baiduNavi = BaiduMapNavigator(context)
                }
            }
            return baiduNavi
        }

    }

    private val eventListerner: BaiduNaviManager.NavEventListener
            = BaiduNaviManager.NavEventListener { what, arg1, arg2, bundle -> BNEventHandler.getInstance().handleNaviEvent(what, arg1, arg2, bundle) }

    /** 初始化导航 **/
    fun initNavigator(context: Context, startNaviName: String, endNaviName: String, naviLatLng: Array) {
        val loadingDialog: MaterialProgressDialog? = DialogUtil.initAndShow(context, MaterialProgressDialog::class.java)
        loadingDialog?.setLoadingText("正在初始化...")
        if (!isBaiduNaviInitSuccess) {
            var authinfo: String?
            val mSDCardPath = SysData.MAIN_APP_DIRECTORY
            File(mSDCardPath, "EdumapNavi").mkdirs()
            BaiduNaviManager.getInstance().init(activity, mSDCardPath, "EdumapNavi", object : BaiduNaviManager.NaviInitListener {
                override fun onAuthResult(status: Int, msg: String) {
                    if (0 == status) {
                        authinfo = "key校验成功!"
                    } else {
                        authinfo = "key校验失败, " + msg
                    }
                    activity.runOnUiThread({ Toast.makeText(activity, authinfo, Toast.LENGTH_LONG).show() })
                }

                override fun initSuccess() {
                    Toast.makeText(activity, "百度导航引擎初始化成功", Toast.LENGTH_SHORT).show()
                    isBaiduNaviInitSuccess = true

                    //设置语音导航
                    val bundle = Bundle()
                    // 必须设置APPID,否则会静音
                    bundle.putString(BNCommonSettingParam.TTS_APP_ID, BuildConfig.BaiduMapApiKey)
                    BNaviSettingManager.setNaviSdkParam(bundle)

                    BNaviSettingManager.setShowTotalRoadConditionBar(BNaviSettingManager.PreViewRoadCondition.ROAD_CONDITION_BAR_SHOW_ON)

                    DialogUtil.hide(loadingDialog)

            }, null, TTSCallbackHandler(activity), TTSPlayStatusCallback(activity))
        } else {

        BaiduNaviManager.getInstance().launchNavigator(activity, arrayListOf(sNode, eNode), 1, true, BaiduRoutePlanListener(sNode), eventListerner)
    }

    /**

        }

        override fun playEnd() {
            Log.i(BaiduMapNavigator::class.java.simpleName, "status: 播报导航结束...")
        }
    }

    /**

    class TTSCallbackHandler(val context: Context) : Handler() {

        override fun handleMessage(msg: Message) {
            val type = msg.what
            when (type) {
                BaiduNaviManager.TTSPlayMsgType.PLAY_START_MSG -> {
                    Log.i(BaiduMapNavigator::class.java.simpleName, "开始播报导航...")
                }// showToastMsg("Handler : TTS play start");
                BaiduNaviManager.TTSPlayMsgType.PLAY_END_MSG -> {
                    Log.i(BaiduMapNavigator::class.java.simpleName, "播报导航结束...")
                }// showToastMsg("Handler : TTS play end");
                else -> {
                }
            }
        }

    }

}

万事俱备只欠东风,那么该怎么调用呢?

java:

BaiduMapNavigator.getInstance(Activity activity).initNavigator(Context context, String startNaviName, String endNaviName, LatLng[] naviLatLng);

kotlin:

BaiduMapNavigator.getInstance(activity: Activity).initNavigator(context: Context, startNaviName: String, endNaviName: String,  naviLatLng: Array);

功成身退,成败得失

集成第三方SDK其实并不麻烦,麻烦的是第三方提供的文档有时候是有误的或者表述并不明了,亦或者已经过时。这就很需要我们去查看Demo,归纳出我们自己需要的代码精华。集成这次百度导航中,最让我困惑的是arm64-v8a架构的设备找不到libgnustl_shared.so的位置,armeabi-v7a表现正常!
