This worked for me  just put it into any layout you want to    lt FrameLayout     android layout width  32dp      android layout height  192dp  gt        lt SeekBar         android layout width  192dp          android layout height  32dp          android layout gravity  center          android rotation  270    gt    lt  FrameLayout gt

Here is a very good implementation of vertical seekbar  Have a look    http   560b sakura ne jp android VerticalSlidebarExample zip  And Here is my own implementation for Vertical and Inverted Seekbar based on this  https   github com AndroSelva Vertical-SeekBar-Android  protected void onDraw Canvas c        c rotate -90       c translate -getHeight   0        super onDraw c       Override public boolean onTouchEvent MotionEvent event        if   isEnabled              return false             switch  event getAction              case MotionEvent ACTION DOWN          case MotionEvent ACTION MOVE          case MotionEvent ACTION UP              int i 0              i getMax   -  int   getMax     event getY     getHeight                 setProgress i               Log i  Progress  getProgress                    onSizeChanged getWidth    getHeight    0  0               break           case MotionEvent ACTION CANCEL              break            return true

I tried in many different ways  but the one which worked for me was  Use Seekbar inside FrameLayout   lt FrameLayout     android id    id VolumeLayout      android layout width  match parent      android layout height  match parent      android layout above   id MuteButton      android layout below   id volumeText      android layout centerInParent  true  gt           lt SeekBar         android id    id volume          android layout width  500dp          android layout height  60dp          android layout gravity  center          android progress  50          android secondaryProgress  40          android progressDrawable   drawable seekbar volume          android secondaryProgressTint   color tint neutral          android thumbTint   color tint neutral        gt    And in Code   Setup Pre Draw callback on Seekbar  Where you can change the Width and height of the Seekbar I did this part in c   so Code i used was              var volumeSlider   view FindViewById lt SeekBar gt  Resource Id home link volume                var volumeFrameLayout   view FindViewById lt FrameLayout gt  Resource Id linkVolumeFrameLayout                void OnPreDrawVolume object sender  ViewTreeObserver PreDrawEventArgs e                                volumeSlider ViewTreeObserver PreDraw -  OnPreDrawVolume                  var h   volumeFrameLayout Height                  volumeSlider Rotation   270 0f                  volumeSlider LayoutParameters Width   h                  volumeSlider RequestLayout                               volumeSlider ViewTreeObserver PreDraw    OnPreDrawVolume    Here i Add listener to PreDraw Event and when its triggered  I remove the PreDraw so that it doesnt go into Infinite loop   So when Pre Draw gets executed  I fetch the Height of FrameLayout and assign it to Seekbar  And set the rotation of seekbar to 270  As my seekbar is inside frame Layout and its Gravity is set as Center  I dont need to worry about the Translation  As Seekbar always stay in middle of Frame Layout   Reason i remove EventHandler is because seekbar RequestLayout    Will make this event to be executed again

For API 11 and later  can use seekbar s XML attributes android rotation  270   for vertical effect    lt SeekBar android id    id seekBar1  android layout width  match parent  android layout height  wrap content  android rotation  270   gt   For older API level  ex API10   only use Selva s answer    https   github com AndroSelva Vertical-SeekBar-Android

When moving the thumb with an EditText  the Vertical Seekbar setProgress may not work  The following code can help        Override public synchronized void setProgress int progress        super setProgress progress       updateThumb       private void updateThumb         onSizeChanged getWidth    getHeight    0  0       This snippet code found here   https   stackoverflow com a 33064140 2447726

I used Selva s solution but had two kinds of issues    OnSeekbarChangeListener did not work properly Setting progress programmatically did not work properly    I fixed these two issues  You can find the solution  within my own project package  at  https   github com jeisfeld Augendiagnose blob master AugendiagnoseIdea augendiagnoseLib src main java de jeisfeld augendiagnoselib components VerticalSeekBar java

Note  it appears to me that if you change the width the thumb width does not change correctly  I didn t take the time to fix it right  i just fixed it for my case  Here is what i did  Couldn t figure out how to contact the original creator   public void setThumb Drawable thumb        if  thumb    null            thumb setCallback this               Assuming the thumb drawable is symmetric  set the thumb offset            such that the thumb will hang halfway off either edge of the            progress bar            This was orginally divided by 2  seems you have to adjust here when you adjust width          mThumbOffset    int thumb getIntrinsicHeight
