Dialog setting view cannot be centered. dialog setting view Center

Today, when I typed the code, I found that when I set my own view for dialog, I couldn't center the display. It was always printed above the dialog. The Code is as follows:

AlertDialog.Builder builder = new AlertDialog.Builder(this);        builder.setView(R.layout.quick_login_dialog);        builder.setCancelable(false);        AlertDialog alertDialog = builder.create();        alertDialog.show();        int width = DImenUtil.dip2px(this, 150);        int height = DImenUtil.dip2px(this, 130);        alertDialog.getWindow().setLayout(width,height);        alertDialog.getWindow().setBackgroundDrawableResource(R.drawable.quick_login_background);

The xml Code is as follows:

When dialog parses xml, it only recognizes the second-level layout. The second-level layout height changes, and the overall layout height changes, that is, we should regard the Layer 2 Layout as the root layout. The modified xml is as follows:

That is to say, we need to nest another layer and use the nested sub-layout as the root layout. The first layer does not matter because it is useless.
