Android left to right swipe only

Question

I am a beginner in Android. I need to swipe only from left to right and to do not swipe from right to left. For this what I want to do? All the examples are showing both left to right and right to left?

What do you want to happen when you swipe ? Maybe you can post some of the examples you found and explain what you want to do differently... — Matthieu, Sep 24 '12 at 06:04

Take a look at the accepted solution here - Fling gesture detection on grid layout

The solution explains how to implement a simple gesture listener, and record left to right and right to left swipes. The relevant code from the example is in the GestureDetector onFling override method. Basically, if point 1 (e1) minus point 2 (e2) is greater than a set minimum swipe distance, then you know it's right to left. If point 2 (e2) minus point 1 (e1) was greater than the minimum swipe distance then it's left to right.

// 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();
}  
// left to right swipe
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();
}

Kyle, Thanks for your detailed answer. Now I understood about this. — RIJO R V, Sep 24 '12 at 06:32
