Android 如何设置自定义dialog的大小

final View inflate = LayoutInflater.from(StationManagementActivity.this).inflate(R.layout.qrcode, null);
final LinearLayout ll_dialog_id = (LinearLayout) inflate.findViewById(R.id.dialog_id);
ImageView qrcode = (ImageView) inflate.findViewById(R.id.iv_qrcode);
final ImageView guanbi = (ImageView) inflate.findViewById(R.id.iv_guanbi);
final Dialog dialog = new AlertDialog
        .Builder(StationManagementActivity.this)
        .setView(inflate)
        .show();
final WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = 800;
params.height = 1200;
dialog.getWindow().setAttributes(params);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
Glide.with(StationManagementActivity.this).load(list.get(position).getDwhat()).into(qrcode);
Animation animation = AnimationUtils.loadAnimation(StationManagementActivity.this, R.anim.scale);
inflate.setAnimation(animation);
animation.start();
