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();
}

如果您的應用程序崩潰，請分享堆棧跟蹤 – 0xDEADC0DE
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
