    private Dialog dialog;
    public void show(){
        dialog = new Dialog(oThis,R.style.ActionSheetDialogStyle);
        inflate = LayoutInflater.from(oThis).inflate(R.layout.fast_trade_view, null);
        dialog.setContentView(inflate);
        Window dialogWindow = dialog.getWindow();
        dialogWindow.setGravity( Gravity.BOTTOM);
