How to set seekbar min and max value

Question

I have a seekbar and trying to set the value from 60 to 180 for one and 40 to 190 for the second one in step of 1   sb1    SeekBar  findViewById R id progresss           sb1 setOnSeekBarChangeListener new OnSeekBarChangeListener                          Override                    public void onStopTrackingTouch SeekBar seekBar                             TODO Auto-generated method stub                   int inVal   Integer parseInt String valueOf seekBar getProgress                        inVal    70                    Toast makeText getApplicationContext    String valueOf inVal  Toast LENGTH LONG  show                                       Override                    public void onStartTrackingTouch SeekBar seekBar                            TODO Auto-generated method stub                                          Override                    public void onProgressChanged SeekBar seekBar  int progress boolean fromUser                            TODO Auto-generated method stub                 progress    70                  Toast makeText getApplicationContext    String valueOf progress  Toast LENGTH LONG  show                                        is not working  Any idea how to fix it

Min-value will always start at zero and its nothing you can do about it. But you can change its value when user start scrolling it around.

Here I set the max-value as 64. This calculations are simple: I want the user to pick a time from 15min to 16 hours, and he picks one of every 15min to 16 hours, clear? I know, very simple :)

    SeekBar seekBar = (SeekBar) dialog.findViewById(R.id.seekBar);
    seekBar.setMax(64);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        float b;

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            float des = (float) progress / 4;
            b = des;
            hours.setText(des + " hours");
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {


        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            hoursSelected = b;
        }
    });

The easiest way to set a min and max value to a seekbar for me  if you want values min 60 to max 180  this is equal to min 0 max 120  So in your seekbar xml set property   android max  120    min will be always 0   Now you only need to do what your are doing  add the amount to get your translated value in any change  in this case  60       seekBar setOnSeekBarChangeListener new SeekBar OnSeekBarChangeListener              Override         public void onProgressChanged SeekBar seekBar  int progress  boolean fromUser                int translatedProgress   progress   60                      Override         public void onStartTrackingTouch SeekBar seekBar                        Override         public void onStopTrackingTouch SeekBar seekBar                        Be careful with the seekbar property android progress  if you change the range you must recalculate your initial progress  If you want 50   max 2  in my example 120 2   60

Another solution to handle this case is creating a customized Seekbar  to get ride of converting the real value and SeekBar progress every time   import android content Context import android util AttributeSet import android widget SeekBar        Require SeekBar with range  Min  Max  and INCREMENT value     However  Android Seekbar starts from 0 and increment is 1 by default  Android supports min attr on API 26     To make a increment  amp  range Seekbar  we can do the following conversion            seekbar setMax  Max - Min    Increment         seekbar setProgress  actualValue - Min    Increment         seekbar getProgress   Min    progress   Increment        The RangeSeekBar is responsible for handling all these logic inside the class   data class Range val min  Int  val max  Int  private val defaultIncrement  Int        val increment   if   max - min   lt  defaultIncrement  1 else defaultIncrement     internal fun Range toSeekbarMaximum    Int    max - min    increment   class RangeSeekBar  SeekBar  SeekBar OnSeekBarChangeListener        constructor context  Context    super context      constructor context  Context  attrs  AttributeSet    super context  attrs       var range  Range   Range 0  100  1          set value                field   value             max   value toSeekbarMaximum                  var value  Int   0         get     range min   progress   range increment         set value                progress    value - range min    range increment             field   value                var onSeekBarChangeListenerDelegate  OnSeekBarChangeListener    this      override fun setOnSeekBarChangeListener l  OnSeekBarChangeListener             onSeekBarChangeListenerDelegate   l         super setOnSeekBarChangeListener this             override fun onProgressChanged seekBar  SeekBar   progress  Int  fromUser  Boolean            onSeekBarChangeListenerDelegate  onProgressChanged seekBar  value  fromUser             override fun onStartTrackingTouch seekBar  SeekBar             onSeekBarChangeListenerDelegate  onStartTrackingTouch seekBar             override fun onStopTrackingTouch seekBar  SeekBar             onSeekBarChangeListenerDelegate  onStopTrackingTouch seekBar            Then in your fragment           init     range seekbar range   Range 10  110  10      range seekbar value   20         observe value changes     range seekbar userChanges   skipInitialValue   subscribe           println  current value  it           Keywords  Kotlin  range SeekBar  Rx

Seek  Bar has methods for setting max values but not for setting min value here i write a code for setting minimum seek bar value when we add this code then your seek bar values not less then mim value try this its work fine for me       This methods call after seek bar value change                            public void onProgressChanged SeekBar seekBar  int progress                  boolean fromUser                   Check the current seekbar value is greather than min value               if  progress  lt  MIN VALUE                       if seek bar value is lesser than min value then set min value to seek bar                    seekBar setProgress MIN VALUE

You can set max value for your seekbar by using this code      sb1 setMax 100    This will set the max value for your seekbar  But you cannot set the minimum value but yes you can do some arithmetic to adjust value  Use arithmetic to adjust your application-required value  For example  suppose you have data values from -50 to 100 you want to display on the SeekBar  Set the SeekBar s maximum to be 150  100- -50    then subtract 50 from the raw value to get the number you should use when setting the bar position  You can get more info via this link

Set seekbar max and min value   seekbar have method that setmax int position  and setProgress int position    thanks

There is no option to set a min or max value in seekbar   so you can use a formula here to scale your value   Desired value     progress     Max value - Min value    100     Min value   I have tested this formula in many examples  In your example   if the progressBar is the middle i e  progress   50   and your Min val and Max val are 60 and 180 respectively  then this formula will give you the Desired value  120

You cannot set the min value of a SeekBar  always 0  and you cannot set the step value of a SeekBar  always 1    To set the value from 60 to 180 with a step of 1   int step   1  int max   180  int min   60      Ex       If you want values from 3 to 5 with a step of 0 1  3  3 1  3 2       5     this means that you have 21 possible values in the seekbar     So the range of the seek bar will be  0    5-3  0 1   20   seekbar setMax   max - min    step      seekbar setOnSeekBarChangeListener      new OnSeekBarChangeListener                  Override         public void onStopTrackingTouch SeekBar seekBar               Override         public void onStartTrackingTouch SeekBar seekBar               Override         public void onProgressChanged SeekBar seekBar  int progress               boolean fromUser                            Ex                  And finally when you want to retrieve the value in the range you                wanted in the first place - gt   3-5                                if progress   13 - gt  value   3    13   0 1    4 3             double value   min    progress   step                         I put another example within the code so that you understand the math
