我必须从sqlite表中检索所有行，然后通过PHP Webservice将它们插入mysql，但仅插入了第一行。如何在Android中的Mysql表中同时插入多行？

代码以检索sqlite数据

  public String getName(){
    SQLiteDatabase db=getReadableDatabase();
    Cursor cursor = db.rawQuery("SELECT NOMBRE FROM BEBIDAS",null);
    if(cursor.moveToFirst()){
        return cursor.getString(0);
    }
    return "";
}
public int getPrecio(){
    SQLiteDatabase db=getReadableDatabase();
    Cursor cursor = db.rawQuery("SELECT PRECIO FROM BEBIDAS",null);
    if(cursor.moveToFirst()){
        return cursor.getInt(0);
    }
    return 0;
}
public int getCantidad(){
    SQLiteDatabase db=getReadableDatabase();
    Cursor cursor = db.rawQuery("SELECT CANTIDAD FROM BEBIDAS",null);
    if(cursor.moveToFirst()){
        return cursor.getInt(0);
    }
    return 0;
}

Volley请求将详细信息传递给Web服务

private void insertData(String URL){
    StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            if(response.isEmpty()){
                Intent confirm = new Intent(Pagos_Lugares.this, elegirPrefer.class);
                startActivity(confirm);
            }else{
                Toast.makeText(Pagos_Lugares.this,"Error",Toast.LENGTH_SHORT).show();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getApplicationContext(), error.toString(), Toast.LENGTH_SHORT).show();
        }
    }){
        @Override
        protected Map<String,String> getParams() throws AuthFailureError {
            CafeteriaDB cafe= new CafeteriaDB(getApplicationContext());
            Map<String,String> parametros = new HashMap<String,String>();
            parametros.put("nombre",cafe.getName());
            parametros.put("precio",String.valueOf(cafe.getPrecio()));
            parametros.put("cantidad",String.valueOf(cafe.getCantidad()));
            return parametros;
        }
    };
    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);
}

网络服务-php代码在下面给出

<?php
include 'conexion.php';
$nombre=$_POST['nombre'];
$precio=$_POST['precio'];
$cantidad=$_POST['cantidad'];

$consulta="INSERT INTO ordenes_bebidas VALUES('".$nombre."','".$precio."','".$cantidad."')";

mysqli_query($conexion,$consulta) or die (mysqli_error());
mysqli_close($conexion);
?>

谢谢
