高德地圖---路徑規劃---語音導航的開發
阿新 • • 發佈：2018-11-13
第一步匯入高德地圖導航開發包及對應的功能類
第二步路徑規劃的類繼承導航的介面
Activity_NaviChoose extends Activity implements OnRouteSearchListener,AMapNaviListener
OnRouteSearchListener路徑規劃的介面
AMapNaviListener導航的介面
第三步路徑規劃
自駕路徑規劃
/**
* 自駕路徑規劃
*/
public void dringRoute() {
Log.e("route", "--------------dringRoute---------------" 步行路徑規劃
/**
* 步行路徑規劃
*/
public void warkRoute() {
Log.e("route", "--------------warkRoute---------------");
RouteSearch routeSerch=new RouteSearch(Activity_NaviChoose.this);
routeSerch.setRouteSearchListener(this);
LatLonPoint start_lat=new LatLonPoint(la_start, ln_start); //定位本地座標
LatLonPoint end_lat=new LatLonPoint(la_end,ln_end);
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
start_lat, end_lat);
WalkRouteQuery query=new WalkRouteQuery(fromAndTo, RouteSearch.WalkDefault);
routeSerch.calculateWalkRouteAsyn(query);
}公交路徑規劃
public void busRoute() {
RouteSearch routeSerch=new RouteSearch(Activity_NaviChoose.this);
routeSerch.setRouteSearchListener(this);
LatLonPoint start_lat=new LatLonPoint(la_start, ln_start); //定位本地座標
LatLonPoint end_lat=new LatLonPoint(la_end,ln_end);
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
start_lat, end_lat);
//是否計算夜班車，預設為不計算。0：不計算，1：計算。可選
BusRouteQuery query=new BusRouteQuery(fromAndTo, RouteSearch.BusDefault, "北京", 0);
routeSerch.calculateBusRouteAsyn(query);
}第四步 新增路徑規劃回撥方法–重寫介面OnRouteSearchListener的方法
自駕回調
@Override
public void onDriveRouteSearched(DriveRouteResult result, int rCode) {
Log.e("route", "--------------onDriveRouteSearched---------------");
if (rCode == 0) {
if (result != null && result.getPaths() != null
&& result.getPaths().size() > 0) {
DriveRouteResult driveRouteResult = result;
DrivePath drivePath = driveRouteResult.getPaths().get(0);
aMap.clear();// 清理地圖上的所有覆蓋物
DrivingRouteOverlay drivingRouteOverlay = new DrivingRouteOverlay(
this, aMap, drivePath, driveRouteResult.getStartPos(),
driveRouteResult.getTargetPos());
drivingRouteOverlay.removeFromMap();
drivingRouteOverlay.addToMap();
drivingRouteOverlay.zoomToSpan();
CodeToString(new LatLng(la_start, ln_start));
CodeToString(new LatLng(la_end, ln_end));
} else {
Toast.makeText(getApplicationContext(), "對不起 沒有搜尋到相關資料", 0).show();
}
} else if (rCode == 27) {
Toast.makeText(getApplicationContext(), "搜尋失敗 請檢查網路連線", 0).show();
} else if (rCode == 32) {
Toast.makeText(getApplicationContext(), "驗證無效", 0).show();
} else {
Toast.makeText(getApplicationContext()," 未知錯誤 請稍後重試 錯誤碼為"+rCode, 0).show();
}
}步行回撥
@Override
public void onWalkRouteSearched(WalkRouteResult result, int rCode) {
Log.e("route", "--------------onWalkRouteSearched---------------");
if (rCode == 0) {
if (result != null && result.getPaths() != null
&& result.getPaths().size() > 0) {
WalkRouteResult walkRouteResult = result;
WalkPath walkPath = walkRouteResult.getPaths().get(0);
aMap.clear();// 清理地圖上的所有覆蓋物
WalkRouteOverlay walkRouteOverlay = new WalkRouteOverlay(this,
aMap, walkPath, walkRouteResult.getStartPos(),
walkRouteResult.getTargetPos());
walkRouteOverlay.removeFromMap();
walkRouteOverlay.addToMap();
walkRouteOverlay.zoomToSpan();
CodeToString(new LatLng(la_start, ln_start));
CodeToString(new LatLng(la_end, ln_end));
} else {
Toast.makeText(getApplicationContext(), "對不起 沒有搜尋到相關資料", 0).show();
}
} else if (rCode == 27) {
Toast.makeText(getApplicationContext(), "搜尋失敗 請檢查網路連線", 0).show();
} else if (rCode == 32) {
Toast.makeText(getApplicationContext(), "驗證無效", 0).show();
} else {
Toast.makeText(getApplicationContext()," 未知錯誤 請稍後重試 錯誤碼為"+rCode, 0).show();
}
}公交回調
@Override
public void onBusRouteSearched(BusRouteResult result, int rCode) {
Log.e("route", "--------------onBusRouteSearched---------------");
if (rCode == 0) {
if (result != null && result.getPaths() != null
&& result.getPaths().size() > 0) {
BusRouteResult busRouteResult = result;
BusPath busPath = busRouteResult.getPaths().get(0);
//獲取公交換乘路段列表
List<BusStep> steps = busPath.getSteps();
StringBuffer showBusLine = showBusLine(steps);
String string = showBusLine.toString().substring(0, showBusLine.toString().length()-6);
saveNaviLine(string,"gj");
Log.e("公交線路", string);
aMap.clear();// 清理地圖上的所有覆蓋物
BusRouteOverlay routeOverlay = new BusRouteOverlay(this, aMap,
busPath,busRouteResult.getStartPos(),
busRouteResult.getTargetPos()
);
routeOverlay.removeFromMap();
routeOverlay.addToMap();
routeOverlay.zoomToSpan();
} else {
Toast.makeText(getApplicationContext(), "對不起 沒有搜尋到相關資料", 0).show();
}
} else if (rCode == 27) {
Toast.makeText(getApplicationContext(), "搜尋失敗 請檢查網路連線", 0).show();
} else if (rCode == 32) {
Toast.makeText(getApplicationContext(), "驗證無效", 0).show();
} else {
Toast.makeText(getApplicationContext()," 未知錯誤 請稍後重試 錯誤碼為"+rCode, 0).show();
}
}其中公交可以獲取站點的資訊
/**
* @param steps
* 分析公交線路
*/
private StringBuffer showBusLine(List<BusStep> steps) {
sb.delete(0,sb.length());
Log.e("公交路段數量", "----------------------"+steps.size());
for(int i=0;i<steps.size();i++){
BusStep busStep = steps.get(i);
RouteBusLineItem busLine = busStep.getBusLine(); //獲取公交導航資訊
//System.out.println("-------------------"+busLine.toString()); 地鐵1號線(四惠東--蘋果園) 05:05-23:15
if(busLine!=null && !busLine.equals(null)){
Log.e("公交站名稱", "--------------"+busLine.getBusLineName());
BusStationItem arrivalBusStation = busLine.getArrivalBusStation();//到達站
BusStationItem departureBusStation = busLine.getDepartureBusStation();//出發站
String busStationName = arrivalBusStation.getBusStationName();//到達站公交站名稱
String busStationName2 = departureBusStation.getBusStationName();//出發站公交站名稱
Log.e("公交",busLine.getBusLineName()+"到達"+busStationName);
//Log.e("站名","到達站公交站名稱"+busStationName+"出發站公交站名稱"+busStationName2);
sb.append(busLine.getBusLineName()+"到達"+busStationName+"--換乘--");
}else{
Log.e("null", "------------busStep.getBusLine().equals(null)---------------------");
}
}
return sb;
}第五步 新增自駕和步行的導航
第一步 註冊導航和語音
可以在oncreate()方法中註冊
//語音播報開始
TTSController ttsManager = TTSController.getInstance(this);// 初始化語音模組
ttsManager.init();
AMapNavi.getInstance(this).setAMapNaviListener(ttsManager);// 設定語音模組播報
TTSController.getInstance(this).startSpeaking();
//導航註冊
AMapNavi.getInstance(this).setAMapNaviListener(this);第二部 開啟導航的方法
/**
* 開啟導航的方法
*/
public void StartNavi(int i) {
Log.e("navi", "-----------StartNavi-------------");
//起點終點
NaviLatLng mNaviStart = new NaviLatLng(la_start, ln_start);
NaviLatLng mNaviEnd = new NaviLatLng(la_end,ln_end);
//起點終點列表
ArrayList<NaviLatLng> mStartPoints = new ArrayList<NaviLatLng>();
ArrayList<NaviLatLng> mEndPoints = new ArrayList<NaviLatLng>();
mStartPoints.add(mNaviStart);
mEndPoints.add(mNaviEnd);
if(i==1){ //自駕 起點 終點 途經點 模式：最快 最省錢等
AMapNavi.getInstance(this).setAMapNaviListener(this);
AMapNavi.getInstance(this).calculateDriveRoute(mStartPoints,
mEndPoints, null, AMapNavi.DrivingDefault);
}else{ //步行
AMapNavi.getInstance(this).calculateWalkRoute(mNaviStart, mNaviEnd);
}
}第三步 導航的回撥，重寫導航介面AMapNaviListener的方法
其中這個方法標誌著導航成功呼叫導航頁面
@Override
public void onCalculateRouteSuccess() {
Log.e("Navi", "-------onCalculateRouteSuccess--------------------");
Intent intent = new Intent(Activity_NaviChoose.this,
SimpleNaviActivity.class); //導航頁面
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
Bundle bundle=new Bundle();
bundle.putInt(Utils.ACTIVITYINDEX, Utils.SIMPLEGPSNAVI);
bundle.putBoolean(Utils.ISEMULATOR, false);
intent.putExtras(bundle);
startActivity(intent);
}新增導航頁面佈局及相關引數
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.amap.api.navi.AMapNaviView
android:id="@+id/simplenavimap"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>

<string name="preference_key_tts_speed">tts_speed</string>
<string name="preference_title_tts_speed">語速</string>

<string name="preference_title_tts_pitch">語調</string>
<string name="preference_default_tts_pitch">50</string>
<string name="app_id">5613985e</string>最後處理一下導航頁面類的返回按鈕跳轉回哪個頁面即可
