Question

我正在尝试将ListArray coords中的值添加到ListArray linhasCoords，但linhasCoords并未获取所有值。

我的观点是，对于每个ID，保存所有坐标Lat和Long。

public HashMap<Integer, ArrayList<LatLong>> load_RoadAxis() {


        HashMap<Integer,ArrayList<LatLong>> linhasCoords = new HashMap<Integer, ArrayList<LatLong>>();

        ArrayList<LatLong> coords = new ArrayList<LatLong>();

                int idAtual = 0;
                int idAnterior = 1;

        String query = "SELECT y, x, linha2 FROM trechos_pontos WHERE linha2 <5 ORDER BY linha2, path ";
        try {
                Stmt stmt = db.prepare(query);
                while (stmt.step()) {

                        Double x = stmt.column_double(0);
                        Double y = stmt.column_double(1);
                        //Log.d("TRECHOS", "idAtual: " + idAtual + "X: " + x.toString() + "  Y: " + y.toString());
                        idAtual = stmt.column_int(2);

                        Log.d("TRECHOS", "idAtual: " + idAtual + "  idAnterior: " + idAnterior);

                if (idAtual == idAnterior) {

                        coords.add(new LatLong(x,y));
                        Log.d("TRECHOS", " Coords: " + coords);

                } else {

                        linhasCoords.put(idAnterior,coords);

                        idAnterior = idAtual;

                        coords.clear();
                        coords.add(new LatLong(x,y));
                        Log.d("TRECHOS", " LinhasCoords: " + linhasCoords);
                }      
                }
                stmt.close();
            } catch (Exception e) {
                e.printStackTrace();
                Log.d("TRECHOS", "A consulta dos trechos falhou");
            }

        //Log.d("TRECHOS", linhasCoords.toString());
                return linhasCoords;
        }

您可以看到linhasCoords在generated之前没有所有值及其coords，我也不知道为什么。

Answer 1

 if (idAtual == idAnterior) {



                    coords.add(new LatLong(x,y));

                    Log.d("TRECHOS", " Coords: " + coords);



            } else {



                    linhasCoords.put(idAnterior,coords);



                    idAnterior = idAtual;



                    coords.clear();

                    coords.add(new LatLong(x,y));

                    Log.d("TRECHOS", " LinhasCoords: " + linhasCoords);

            }

因此，如果idAtual等于idAnterior，它将不会被添加到linhasCoords，只会添加到coords。替换为：

 if (idAtual == idAnterior) {

                    linhasCoords.put(idAnterior,coords);

                    coords.add(new LatLong(x,y));

                    Log.d("TRECHOS", " Coords: " + coords);



            } else {



                    linhasCoords.put(idAnterior,coords);



                    idAnterior = idAtual;



                    coords.clear();

                    coords.add(new LatLong(x,y));

                    Log.d("TRECHOS", " LinhasCoords: " + linhasCoords);

            }

将列表中的值添加到另一个列表中
