                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                Gravity.CENTER);
        View toastView = toast.getView();
        toastView.setLayoutParams(layoutParams);
        toast.setGravity(Gravity.CENTER, 0, 0); //居中显示
        toast.show();
