View没有加载在布局上，还想测量View的宽和高

//先用layoutinflater搞成一个view然后再调用方法测量
MarkMapAnchorBinding markMapAnchorBinding = MarkMapAnchorBinding.inflate(getLayoutInflater());
getHeight(activity,binding.getRoot());

public static int getHeight(baseActivity context, View v){
        DisplayMetrics metric =new DisplayMetrics();
        context.getWindowManager().getDefaultDisplay().getMetrics(metric);
        int width = metric.widthPixels;
        int height = metric.heightPixels;

        int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
        int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.AT_MOST);

        v.measure(measuredWidth, measuredHeight);
        return v.getMeasuredHeight();
    }
