Answer 1

Nothing here worked for me, so I've came with a bit different solution. I noticed that everything is working well until I try to change maximal value (calling setMax with different value).

My code:

class FixedSeekBar : SeekBar {

    constructor(context: Context) : super(context)
    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)
    constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    companion object {
        private const val PROGRESS_MAX = 1000000.toDouble()
    }

    private var mLastMaxValue: Int = 100

    override fun setMax(max: Int) {
        mLastMaxValue = max
        super.setMax(PROGRESS_MAX.toInt())
    }

    fun setProgressFixed(progress: Int) {
        setProgress((PROGRESS_MAX / mLastMaxValue * progress).toInt())
    }

    fun getProgressFixed(): Int {
        return (getProgress() / PROGRESS_MAX * mLastMaxValue).toInt()
    }

}

This works perfectly for me. I can call setMax as usually and I just need to replace getProgress and setProgress with getProgressFixed and setProgressFixed.

Do not override setProgress and getProgress. They are called internally.

My solution doesn't count with setMin. If you need it, change the code accordingly.
