Create Simple gesture for swipe left to right and right to left

Question

I want to create simple swipe gestures between two activity ,i have searched a lot got something like below.But my doubt is how could i swipe the activity or view using swipe gesture!!

class MyGestureDetector extends SimpleOnGestureListener {
        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            try {
                if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
                    return false;
                // right to left swipe
                if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    Toast.makeText(SelectFilterActivity.this, "Left Swipe", Toast.LENGTH_SHORT).show();
                }  else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    Toast.makeText(SelectFilterActivity.this, "Right Swipe", Toast.LENGTH_SHORT).show();
                }
            } catch (Exception e) {
                // nothing
            }
            return false;
        }

Hope anybody will help me out @Thanks!

Have you tried with viewpager ..do you mean you want two pages in a singlescreen..here by using viewpager by left and right swipe you can show pages whats wrong in it. — Abhijit Chakra, Apr 05 '13 at 10:02
Abhijit i have done it using view pager but getting continuous pages one after another using swipe.BUT in my case i dont need continuous swipe if i swipe left the the left view should open and swipe right the right view activity should show.. — , Apr 05 '13 at 10:07

Try this code now..

page = (LinearLayout) findViewById(R.id.flipper);

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    super.dispatchTouchEvent(event);
    return gestureDetector.onTouchEvent(event);
}

SimpleOnGestureListener simpleOnGestureListener = new SimpleOnGestureListener() {

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {

        float sensitvity = 50;
        if ((e1.getX() - e2.getX()) > sensitvity) {
            SwipeLeft();
        } else if ((e2.getX() - e1.getX()) > sensitvity) {
            SwipeRight();
        }

        return true;
    }

};

 GestureDetector gestureDetector = new GestureDetector(
        simpleOnGestureListener);



private void SwipeLeft() {

     page.setInAnimation(animFlipInForeward);
      page.setOutAnimation(animFlipOutForeward);
      page.showNext();

}


 private void SwipeRight() { 

     page.setInAnimation(animFlipInBackward);
     page.setOutAnimation(animFlipOutBackward);
     page.showPrevious();

}

implement your activity with OnGestureListener

 yourview.setOnTouchListener(touchListener);

implement touchListener as shown below

 OnTouchListener touchListener = new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                gestureScanner.onTouchEvent(event);
                return false;
            }
        };

onFling method for swipe.

  public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
                    float velocityY) {
                try {
//                  if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
//                      return false;
                    // right to left swipe
                     if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE  && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                         viewFlipper.setInAnimation(animFlipInPrevious);
                         viewFlipper.setOutAnimation(animFlipOutPrevious);
                         Globle.falg =false;
                    if (count != 2) {
                        if (count == 2) {
                            count = 0;
                        } else {
                            count = count + 1;
                        }
                        if (currentView == 0) {
                            viewFlipper.showNext();
                            currentView = 1;
                        } else if (currentView == 1) {
                            viewFlipper.showNext();
                            currentView = 2;
                        } else {
                            currentView = 0;
                            viewFlipper.showNext();
                        }
                    }
                    count = viewFlipper.getDisplayedChild();
                    } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE  && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                        viewFlipper.setInAnimation(animFlipInNext);
                        viewFlipper.setOutAnimation(animFlipOutNext);
                        Globle.falg =false;
                    if (count != 0) {
                        if (count == 0) {
                            count = 2;
                        } else {
                            count = count - 1;
                        }
                        if (currentView == 2) {
                            currentView = 1;
                            viewFlipper.showPrevious();
                        } else if (currentView == 1) {
                            currentView = 0;
                            viewFlipper.showPrevious();
                        } else {
                            currentView = 2;
                            viewFlipper.showPrevious();
                        }
                    }
                    count = viewFlipper.getDisplayedChild();
                }
                } catch (Exception e) {
                    // nothing
                }
                return false;
            }
        }

as above code you can change your view and here in my case there is three view but you need only two so change above count value. hop this is helpful to you.
