将TextView与progressbar的进度对齐 [英] Align TextView with the progress of progressbar

问题描述

如何将 TextView 与水平的 ProgressBar 的进度对齐.我想在 ProgressBar 的进度位置正上方放置一个 TextView .进度可能会更改.另外，我希望将 TextView 保留在一行中，尽管文本长度可能会更改.

How can I align a TextView with the progress of a horizontal ProgressBar. I want to put a TextView right above the progress position of the ProgressBar. The progress might be changed. Also, I want the TextView to be kept in one line, although the text length might be changed.

推荐答案

从progressBar计算拇指的x位置并将其应用于textview

Calculate the x position of thumb from progressBar and apply it to textview

 var xPosition=  (((seekBar.right - seekBar.left) / seekBar.max) * seekBar.progress ) + seekBar.left

 progressTextView.translationX = xPosition.toFloat() - (progressTextView.width/2)
