每當它嘗試創建線條時,它都會崩潰。我想使用PathOverlay,但它已被棄用。我想創建一條線。Android應用程序每次創建折線時都會崩潰

public void drawLine(){ 
    List<GeoPoint> track = new ArrayList<>(); 
    track.add(new GeoPoint(14.4889,121.0325)); 
    track.add(new GeoPoint(14.4906,121.0353)); 

    Polyline roadOverlay = new Polyline(map.getContext()); 
    roadOverlay.setPoints(track); 
    map.getOverlays().add(roadOverlay); 
    map.invalidate(); 
}

我認爲這會有幫助嗎?我的osmdroid瓷磚在我的手機存儲:

如果您的應用程序崩潰,請分享堆棧跟蹤 – 0xDEADC0DE

+0

檢查map是否爲空* – kId

我不知道在哪裏可以找到堆棧跟蹤,但是我編輯它以便在Gradle控制檯上查看消息。我在我的android手機上運行該程序。如果我刪除了drawLine(),它正在運行並且沒有錯誤。 – Temmie

嘗試刪除map.invalidate(); ..我猜它不需要onCreate作爲視圖將在onCreate存在後作出。
