谷歌地圖折線不工作在Android版本5.0（棒棒糖）

我想繪製折線爲googlemap，它工作正常到Android版本4.4（kitkat），但它不工作在Android 5.0（棒棒糖）。還有什麼做棒棒糖的工作。請你幫我鋤解決這個問題，這是我的谷歌地圖代碼谷歌地圖折線不工作在Android版本5.0（棒棒糖）

請描述你的問題 – Xcihnegn 2015-02-23 08:59:07

@Xingchen我顯示谷歌地圖與標記和折線它工作正常到Android 4.4，但Android 5.0聚線不來。多行意味着，例如，我想從當前位置（gps）到目的地位置繪製線，因爲我使用多行線，這是工作達4.4，但不工作在5.0這是我的問題 – 2015-02-23 10:33:52

你的意思是折線不顯示沒有任何錯誤？ – Xcihnegn 2015-02-23 10:36:45

嘗試修改後的代碼爲您onPostExecute：

@Override 
protected void onPostExecute(List<List<HashMap<String, String>>> result) { 
     ArrayList<LatLng> points = null; 
     //PolylineOptions lineOptions = null; 

     //MarkerOptions markerOptions = new MarkerOptions(); 

     points = new ArrayList<LatLng>(); 

     // Traversing through all the routes 
     for(int i=0;i<result.size();i++){ 
      //points = new ArrayList<LatLng>(); 
      //lineOptions = new PolylineOptions();    

      // Fetching i-th route 
      List<HashMap<String, String>> path = result.get(i); 

      // Fetching all the points in i-th route 
      for(int j=0;j<path.size();j++){ 
       HashMap<String,String> point = path.get(j);     

       double lat = Double.parseDouble(point.get("lat")); 
       double lng = Double.parseDouble(point.get("lng")); 
       LatLng position = new LatLng(lat, lng); 

       points.add(position);      
      } 

      // Adding all the points in the route to LineOptions 
      //lineOptions.addAll(points); 
      //lineOptions.width(4); 
      //lineOptions.color(Color.BLUE); 

     } 

     // Drawing polyline in the Google Map for the i-th route 
     //map.addPolyline(lineOptions); 

     lineOptions.addAll(points); 
     lineOptions.width(4); 
     lineOptions.color(Color.BLUE); 
     line = map.addPolyline(lineOptions); 
    }

我之前points例如for循環動了你的列表，並且還在for循環之後的lineOptions。

希望得到這個幫助。

雅這是工作很好，非常感謝，但請你解釋這個問題的原因。我需要知道爲什麼以前它不工作，現在它是如何工作的 – 2015-02-23 12:50:50

現在Google又發佈了一個新API，但他們沒有正確更新文檔。要連接到API，您需要創建一個Google Play服務API客戶端實例。

mGoogleApiClient = new GoogleApiClient.Builder(this) 
    .addConnectionCallbacks(this) 
    .addOnConnectionFailedListener(this) 
    .addApi(LocationServices.API) 
    .build();

連接到Google Play服務和位置服務API後，您可以獲取用戶設備的最後一個已知位置。當您的應用程序連接到這些應用程序時，您可以使用融合位置提供程序的getLastLocation（）方法來檢索設備位置。要做到這一點，你必須在你的類/活動

implements 
    ConnectionCallbacks, OnConnectionFailedListener

然後實現這個接口，你可以發現這個實現的方法

@Override 
    public void onConnected(Bundle bundle) { 
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
       mGoogleApiClient); 
     if (mLastLocation != null) { 
      mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude())); 
      mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude())); 
     } 
    } 

    @Override 
    public void onConnectionSuspended(int i) { 

    } 

    @Override 
    public void onConnectionFailed(ConnectionResult connectionResult) { 

    }
