我有这段代码，当我使用两者中的任何一个（getString（1），getString（3），getString（4））时似乎都很好但是当我使用它们中的三个并将它们分配到一个变量，我的应用程序似乎崩溃。
String replaceNodeFormat = joinNodes_all.replace(",,", ","); // ,1-5,,5-6,,6-7, => ,1-5,5-6,6-7,
cursor = db.rawQuery("SELECT * FROM angkutan_umum where simpul like '%" + replaceNodeFormat + "%'", null);
cursor.moveToFirst();
cursor.moveToPosition(0);
// ada 1 angkot yg melewati jalur dari awal sampek akhir
if(cursor.getCount() > 0){
String transpoName = cursor.getString(1).toString();
String type = cursor.getString(3).toString();
// get coordinate
cursor = db.rawQuery("SELECT jalur FROM graph where simpul_awal = '" + initialNodeDijkstra + "'", null);
cursor.moveToFirst();
String json_coordinate = cursor.getString(0).toString();
// manipulating JSON
JSONObject jObject = new JSONObject(json_coordinate);
JSONArray jArrCoordinates = jObject.getJSONArray("coordinates");
JSONArray latlngs = jArrCoordinates.getJSONArray(0);
// first latlng
Double lats = latlngs.getDouble(0);
Double lngs = latlngs.getDouble(1);
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(lats, lngs))
.title(type)
.snippet(transpoName)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.car))).showInfoWindow();
transpoType = type;
// die()\
return;
}
任何帮助将不胜感激，提前谢谢！
