how to use both Ontouch and Onclick for an ImageButton?
To have Click Listener
, DoubleClick Listener
, OnLongPress Listener
, Swipe Left
, Swipe Right
, Swipe Up
, Swipe Down
on Single View
you need to setOnTouchListener
. i.e,
view.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {
@Override
public void onClick() {
super.onClick();
// your on click here
}
@Override
public void onDoubleClick() {
super.onDoubleClick();
// your on onDoubleClick here
}
@Override
public void onLongClick() {
super.onLongClick();
// your on onLongClick here
}
@Override
public void onSwipeUp() {
super.onSwipeUp();
// your swipe up here
}
@Override
public void onSwipeDown() {
super.onSwipeDown();
// your swipe down here.
}
@Override
public void onSwipeLeft() {
super.onSwipeLeft();
// your swipe left here.
}
@Override
public void onSwipeRight() {
super.onSwipeRight();
// your swipe right here.
}
});
}
For this you need OnSwipeTouchListener
class that implements OnTouchListener
.
public class OnSwipeTouchListener implements View.OnTouchListener {
private GestureDetector gestureDetector;
public OnSwipeTouchListener(Context c) {
gestureDetector = new GestureDetector(c, new GestureListener());
}
public boolean onTouch(final View view, final MotionEvent motionEvent) {
return gestureDetector.onTouchEvent(motionEvent);
}
private final class GestureListener extends GestureDetector.SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
@Override
public boolean onDown(MotionEvent e) {
return true;
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
onClick();
return super.onSingleTapUp(e);
}
@Override
public boolean onDoubleTap(MotionEvent e) {
onDoubleClick();
return super.onDoubleTap(e);
}
@Override
public void onLongPress(MotionEvent e) {
onLongClick();
super.onLongPress(e);
}
// Determines the fling velocity and then fires the appropriate swipe event accordingly
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
}
} else {
if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
onSwipeDown();
} else {
onSwipeUp();
}
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
return result;
}
}
public void onSwipeRight() {
}
public void onSwipeLeft() {
}
public void onSwipeUp() {
}
public void onSwipeDown() {
}
public void onClick() {
}
public void onDoubleClick() {
}
public void onLongClick() {
}
}
Try this, It may help you
No need to set onClick()
method onTouch()
will handle both the case.
