I wrote a simple class that makes it easy to detect the swipe events - TOP, RIGHT, BOTTOM, LEFT.

1: Detect single swipe event

// Detect and consume specific events
// {Available methods} - detectTop, detectRight, detectBottom, detectLeft
SwipeEvents.detectTop(swipeElement, new SwipeEvents.SwipeSingleCallback() {
    @Override
    public void onSwipe() {
        showToast("Swiped - detectTop");
    }
});

2: Detect any of the swipe events with one callback.

SwipeEvents.detect( swipeElement, new SwipeEvents.SwipeCallback() {
    @Override
    public void onSwipeTop() {
        //Swiped top
    }

    @Override
    public void onSwipeRight() {
        //Swiped right
    }

    @Override
    public void onSwipeBottom() {
        //Swiped bottom
    }

    @Override
    public void onSwipeLeft() {
        //Swiped left
    }
});

Here is a blog post with the explanation on how to use: http://bmutinda.com/android-detect-swipe-events/

I have also created a Gist for the code snippets available here: https://gist.github.com/bmutinda/9578f70f1df9bd0687b8

Thanks.

Short and easy version   1  First create this abstract class  public abstract class HorizontalSwipeListener implements View OnTouchListener        private float firstX      private int minDistance       HorizontalSwipeListener int minDistance            this minDistance   minDistance             abstract void onSwipeRight         abstract void onSwipeLeft          Override     public boolean onTouch View view  MotionEvent event             switch  event getAction                  case MotionEvent ACTION DOWN                  firstX   event getX                    return true              case MotionEvent ACTION UP                  float secondX   event getX                    if  Math abs secondX - firstX   gt  minDistance                        if  secondX  gt  firstX                            onSwipeLeft                          else                           onSwipeRight                                                            return true                    return view performClick               2 Then create a concrete class implementing what you need   public class SwipeListener extends HorizontalSwipeListener        public SwipeListener             super 200               Override     void onSwipeRight             System out println  right                Override     void onSwipeLeft             System out println  left

After a full day working on this feature finally able to get the right answer      First  create the following classes    import android util Log  import android view MotionEvent  import android view View          Created by hoshyar on 1 19 17       public class SwipeDetector implements View OnTouchListener        public static enum Action           LR     Left to Right         RL     Right to Left         TB     Top to bottom         BT     Bottom to Top         None    when no action was detected            private static final String logTag    Swipe       private static final int MIN DISTANCE   100      private float downX  downY  upX  upY      private Action mSwipeDetected   Action None       public boolean swipeDetected             return mSwipeDetected    Action None             public Action getAction             return mSwipeDetected              Override     public boolean onTouch View v  MotionEvent event            switch  event getAction                  case MotionEvent ACTION DOWN                  downX   event getX                    downY   event getY                    mSwipeDetected   Action None                  return false               case MotionEvent ACTION MOVE                  upX   event getX                    upY   event getY                     float deltaX   downX - upX                  float deltaY   downY - upY                  Log i logTag String valueOf deltaX                    Log i logTag String valueOf deltaX                     if  deltaY gt 0  amp  amp  deltaY lt 10  amp  amp  deltaX lt 0    deltaY  0  amp  amp  deltaX gt -15  amp  amp  deltaX lt 0                       Log i logTag  to right                     if  deltaY gt  0  amp  amp  deltaY lt 10  amp  amp  deltaX gt 0    deltaY lt 0  amp  amp  deltaX gt 15  amp  amp  deltaX lt 40                   Log i logTag  to left                                       if  Math abs deltaX   gt  MIN DISTANCE                           left or right                     if  deltaX  lt  0                            mSwipeDetected   Action LR                          return false                                            if  deltaX  gt  0                              mSwipeDetected   Action RL                          return false                                          else if  Math abs deltaY   gt  MIN DISTANCE                          if  deltaY  lt  0                            Log i logTag  to bottom                            mSwipeDetected   Action TB                          return false                                            if  deltaY  gt  0                            Log i logTag  to up                            mSwipeDetected   Action BT                          return false                                                          return true                    return false               Finally on the object that you want to apply    My example    SwipeDetector swipeDetector   new SwipeDetector    listView setOnTouchListener swipeDetector     Good luck

I want to add on to the accepted answer which works partially  but is missing the time variable  that makes it perfect   Simplest left to right swipe detector with a time variable   In your activity class add following attributes   private float x1 x2  private long startClickTime  static final int MIN DISTANCE   150  static final int MAX SWIPE TIME   200    and override onTouchEvent    method        Override     public boolean onTouchEvent MotionEvent event                switch event getAction                          case MotionEvent ACTION DOWN                  startClickTime   Calendar getInstance   getTimeInMillis                    x1   event getX                    break              case MotionEvent ACTION UP                  long clickDuration   Calendar getInstance   getTimeInMillis   - startClickTime                  x2   event getX                    float deltaX   x2 - x1                  if  Math abs deltaX   gt  MIN DISTANCE  amp  amp  clickDuration  lt  MAX SWIPE TIME                                        Toast makeText this   left2right swipe   Toast LENGTH SHORT  show                                       else                                          consider as something else - a screen tap for example                                   break                    return super onTouchEvent event

Swipe events are a kind of onTouch events  Simply simplifying  Gal Rom  s answer  just keep track of the vertical an horizontal deltas  and with a little math you can determine what kind of swipe a touchEvent was   Again  let me stress that this was OBSENELY based to a previous answer  but the simplicity may appeal to novices   The idea is to extend an OnTouchListener  detect what kind of swipe  touch  just happened and call specific methods for each kind   public class SwipeListener implements View OnTouchListener       private int min distance   100      private float downX  downY  upX  upY      View v        Override     public boolean onTouch View v  MotionEvent event            this v   v          switch event getAction         Check vertical and horizontal touches             case MotionEvent ACTION DOWN                    downX   event getX                    downY   event getY                    return true                            case MotionEvent ACTION UP                    upX   event getX                    upY   event getY                     float deltaX   downX - upX                  float deltaY   downY - upY                     HORIZONTAL SCROLL                 if  Math abs deltaX   gt  Math abs deltaY                         if  Math abs deltaX   gt  min distance                               left or right                         if  deltaX  lt  0                                this onLeftToRightSwipe                                return true                                                    if  deltaX  gt  0                                this onRightToLeftSwipe                                return true                                                  else                             not long enough swipe                            return false                                                            VERTICAL SCROLL                 else                       if  Math abs deltaY   gt  min distance                               top or down                         if  deltaY  lt  0                                this onTopToBottomSwipe                                return true                                                    if  deltaY  gt  0                                this onBottomToTopSwipe                                return true                                                  else                             not long enough swipe                            return false                                                          return false                                  return false             public void onLeftToRightSwipe            Toast makeText v getContext    left to right                                            Toast LENGTH SHORT  show               public void onRightToLeftSwipe             Toast makeText v getContext    right to left                                        Toast LENGTH SHORT  show               public void onTopToBottomSwipe             Toast makeText v getContext    top to bottom                                         Toast LENGTH SHORT  show               public void onBottomToTopSwipe             Toast makeText v getContext    bottom to top                                        Toast LENGTH SHORT  show

This is a cute class I use   in cases I want to catch event on a View  if it is a ViewGroup  I use the second implementation    import android util Log  import android view MotionEvent  import android view View   public class SwipeDetector implements View OnTouchListener       private int min distance   100      private float downX  downY  upX  upY      private View v       private onSwipeEvent swipeEventListener         public SwipeDetector View v           this v v          v setOnTouchListener this              public void setOnSwipeListener onSwipeEvent listener                try              swipeEventListener listener                    catch ClassCastException e                        Log e  ClassCastException   please pass SwipeDetector onSwipeEvent Interface instance  e                         public void onRightToLeftSwipe            if swipeEventListener  null              swipeEventListener SwipeEventDetected v SwipeTypeEnum RIGHT TO LEFT           else             Log e  SwipeDetector error   please pass SwipeDetector onSwipeEvent Interface instance               public void onLeftToRightSwipe            if swipeEventListener  null              swipeEventListener SwipeEventDetected v SwipeTypeEnum LEFT TO RIGHT           else             Log e  SwipeDetector error   please pass SwipeDetector onSwipeEvent Interface instance               public void onTopToBottomSwipe            if swipeEventListener  null              swipeEventListener SwipeEventDetected v SwipeTypeEnum TOP TO BOTTOM           else             Log e  SwipeDetector error   please pass SwipeDetector onSwipeEvent Interface instance               public void onBottomToTopSwipe            if swipeEventListener  null              swipeEventListener SwipeEventDetected v SwipeTypeEnum BOTTOM TO TOP           else             Log e  SwipeDetector error   please pass SwipeDetector onSwipeEvent Interface instance               public boolean onTouch View v  MotionEvent event            switch event getAction             case MotionEvent ACTION DOWN                downX   event getX                downY   event getY                return true                    case MotionEvent ACTION UP                upX   event getX                upY   event getY                 float deltaX   downX -

I think what you want is called a fling  The MotionEvents can be used to determine the direction of the fling   public class MainActivity extends Activity implements  GestureDetector OnGestureListener        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout stellar layout           mDetector   new GestureDetectorCompat this  this               Override     public boolean onFling MotionEvent event1  MotionEvent event2                             float velocityX  float velocityY            Log d tag   onFling  n     event1 toString      n     event2 toString                prints the following             MotionEvent   action ACTION DOWN  id 0  0  x 0  297 0  y 0  672 0  toolType 0  TOOL TYPE FINGER  buttonState 0  metaState 0  flags 0x0  edgeFlags 0x0  pointerCount 1  historySize 0  eventTime 488341979  downTime 488341979  deviceId 6  source 0x1002               MotionEvent   action ACTION UP  id 0  0  x 0  560 0  y 0  583 0  toolType 0  TOOL TYPE FINGER  buttonState 0  metaState 0  flags 0x0  edgeFlags 0x0  pointerCount 1  historySize 0  eventTime 488342047  downTime 488341979  deviceId 6  source 0x1002                      return true             http   developer android com training gestures detector html

the best answer is  Gal Rom  s  there is more information about it  touch event return s to child views first  and if you define onClick or onTouch listener for them  parnt view  for example fragment  will not receive any touch listener  So if you want define swipe listener for fragment in this situation  you must implement it in a new class       package com neganet QRelations fragments   import android content Context  import android util AttributeSet  import android view MotionEvent  import android widget FrameLayout   public class SwipeListenerFragment extends FrameLayout       private float x1 x2      static final int MIN DISTANCE 150      private onSwipeEventDetected mSwipeDetectedListener        public SwipeListenerFragment Context context            super context              public SwipeListenerFragment Context context  AttributeSet attrs            super context  attrs              public SwipeListenerFragment Context context  AttributeSet attrs  int defStyleAttr            super context  attrs  defStyleAttr               Override     public boolean onInterceptTouchEvent MotionEvent ev            boolean result false          switch ev getAction                          case MotionEvent ACTION DOWN                  x1   ev getX                    break              case MotionEvent ACTION UP                  x2   ev getX                    float deltaX   x2 - x1                  if  Math abs deltaX   gt  MIN DISTANCE                                        if deltaX lt 0                                                result true                          if mSwipeDetectedListener  null                              mSwipeDetectedListener swipeLeftDetected                          else if deltaX gt 0                           result true                          if mSwipeDetectedListener  null                              mSwipeDetectedListener swipeRightDetected                                                            break                    return result             public interface onSwipeEventDetected               public void swipeLeftDetected            public void swipeRightDetected                public void registerToSwipeEvents onSwipeEventDetected listener                this mSwipeDetectedListener listener            I changed  Gal Rom  s class  So it can detect both right and left swipe and specially it returns onInterceptTouchEvent true after detect  its important because if we dont do it some times child views maybe receive event and both of Swipe for fragment and onClick for child view  for example  runs and cause some issues   after making this class  you must change your fragment xml file        lt com neganet QRelations fragments SwipeListenerFragment xmlns android  http   schemas android com apk res android      xmlns tools  http   schemas android com tools  android layout width  match parent      android id    id main list layout      android clickable  true      android focusable  true      android focusableInTouchMode  true      android layout height  match parent  tools context  com neganet QRelations fragments mainList      android background   color main frag back  gt        lt  -- TODO  Update blank fragment layout -- gt       lt android support v7 widget RecyclerView         android id    id farazList          android scrollbars  horizontal          android layout width  match parent          android layout height  match parent          android layout gravity  left center vertical    gt   lt  com neganet QRelations fragments SwipeListenerFragment gt    you see that begin tag is the class that we made  now in fragment class               View view inflater inflate R layout fragment main list  container  false           SwipeListenerFragment tdView  SwipeListenerFragment  view          tdView registerToSwipeEvents this     and then Implement SwipeListenerFragment onSwipeEventDetected in it            Override     public void swipeLeftDetected             Toast makeText getActivity     left   Toast LENGTH SHORT  show                Override     public void swipeRightDetected             Toast makeText getActivity     right   Toast LENGTH SHORT  show            It s a little complicated but works perfect

Left to Right and Right to Left Swipe Detector  Firstly  declare two variable of float datatype    private float x1  x2    Secondly  wireup your xml view in java  Like I have ImageView  ImageView img    ImageView  findViewById R id imageView     Thirdly  setOnTouchListener on your ImageView   img setOnTouchListener                      new View OnTouchListener                          Override                     public boolean onTouch View v  MotionEvent event                               TODO Auto-generated method stub                         switch  event getAction                              case MotionEvent ACTION DOWN                              x1   event getX                                break                          case MotionEvent ACTION UP                              x2   event getX                                float deltaX   x2 - x1                              if  deltaX  lt  0                                    Toast makeText MainActivity this                                           Right to Left swipe                                           Toast LENGTH SHORT  show                                 else if deltaX  gt 0                                   Toast makeText MainActivity this                                           Left to Right swipe                                           Toast LENGTH SHORT  show                                                              break                                                     return false

You should be extend a class from View OnTouchListener and handle the onTouch method by overriding it   interface SwipeListener       fun onSwipeLeft       fun onSwipeRight      class SwipeGestureListener internal constructor      private val listener  SwipeListener      private val minDistance  Int   DEFAULT SWIPE MIN DISTANCE     View OnTouchListener       companion object           const val DEFAULT SWIPE MIN DISTANCE   200            private var anchorX   0F      override fun onTouch view  View  event  MotionEvent   Boolean           when  event action                MotionEvent ACTION DOWN - gt                    anchorX   event x                 return true                           MotionEvent ACTION UP - gt                    if  abs event x - anchorX   gt  minDistance                        if  event x  gt  anchorX                            listener onSwipeRight                         else                           listener onSwipeLeft                                                           return true                                 return view performClick             You can just easily implement it like this in your Activity or Fragment   class MainActivity   AppCompatActivity    SwipeListener       override fun onCreate savedInstanceState  Bundle             super onCreate savedInstanceState          setContentView R layout activity main          viewGroup setOnTouchListener SwipeGestureListener this              override fun onSwipeLeft             Toast makeText this   Swipe Left   Toast LENGTH SHORT  show              override fun onSwipeRight             Toast makeText this   Swipe Right   Toast LENGTH SHORT  show
