获取textview的宽度

今天用到了记录下
当TextView的属性是wrap_content时，如何获取其宽度，特别是在界面还没显示时，比如像在RecycleView中的情况？

TextView tv_name = findViewById(R.id.tv_name); tv_name .setText(str);
int spec=View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
tv_name.measure(spec,spec);
int measuredWidthTicketNum = tv_name.getMeasuredWidth();
