public ReadTopUtilsDialog(@NonNull Context context, View contentView) {
        super(context, R.style.ActionSheetDialogStyle);
        this.contentView = contentView;
        Window window = this.getWindow();
        // 设置dialog 显示的位置 默认center 显示再屏幕中间  现设置显示再顶部
        window.setGravity(Gravity.TOP);
        // 设置dialog 进出场动画  
        window.setWindowAnimations(R.style.ReadTopUtilsDialog);
        // 设置dialog 尺寸 和偏移
        window.getDecorView().setPadding(0, 0, 0, 0);
        WindowManager.LayoutParams lp = window.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        // 前2 个flag设置dialog 显示到状态栏    第三个设置点击dialog以外的蒙层 不抢夺焦点  响应点击事件
        lp.flags = WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
        lp.dimAmount = 0.0f;
        window.setAttributes(lp);
        // 设置点击蒙层不消失
        setCanceledOnTouchOutside(false);
    }

设置显示到状态栏在自定义dialog里设置 lp.flags = WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN 即可
