So I have a layout that is made of GridView
and I want to add an OnTouchListener
to handle the event when the user swipes left or right, so I made a class that implements OnTouchListener
it's called OnSwipeTouchListener
and it's working really good but the problem is my gridView, the scroll is working fine and everything but when I click on an item it automatically chooses the first item in the row. any idea on how to fix this or another way to detect a left or right swipe and makes the gridview work fine, thanks.
PS: the gridView works fine when I remove the onTouchListener.
The OnSwipeTouchListner:
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector;
public OnSwipeTouchListener(Context context) {
gestureDetector = new GestureDetector(context, new GestureListener());
}
public void onSwipeLeft() {
}
public void onSwipeRight() {
}
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_DISTANCE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
@Override
public boolean onDown(MotionEvent e) {
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
float distanceX = e2.getX() - e1.getX();
float distanceY = e2.getY() - e1.getY();
if (Math.abs(distanceX) > Math.abs(distanceY) && Math.abs(distanceX) > SWIPE_DISTANCE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (distanceX > 0)
onSwipeRight();
else
onSwipeLeft();
return true;
}
return false;
}
}
}
calling it in the main activity:
gridView.setOnTouchListener(new OnSwipeTouchListener(this){
public void onSwipeRight() {
}
public void onSwipeLeft() {
}
});
Try using setOnItemClickListener
gridView.setOnItemClickListener(
new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View view, int arg2, long arg3) {
}
});
);
