在activity中：

<路径.VerticalSeekBar
                android:id="@+id/seekBar"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>

在代码中

    binding.seekBar.apply {
            setMaxProgress(100f)
            progress = 50f
            setOnProgressChangedListener {
               
            }
        }
