differenciate Swipe and tap getsures android

Question

I'm trying to make note app and have some problems : I have custom Edittext inside custom LinearLayout and trying to handle swipe on Edittext. I'm using this solution of swipe recognition OnSwipeTouchListener and it works perfect, until I tap on edittext (in witch case edittext doesn't get focus). I set OnSwipeTouchListener as edittext.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 onSingleTapConfirmed(MotionEvent e){ print(211212, "singleTap shemovida"); return false; } @Override public boolean onDown(MotionEvent e) { return true; } // 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; print(21512512, "fling"); 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; } } static void print(int line, String st){ PRINT.print("ONSwipeTouchListener", line, st); } public void onSwipeRight() { } public void onSwipeLeft() { } public void onSwipeUp() { } public void onSwipeDown() { }

and I set it to edittext

 void addTextView(){ _myText = new CustomEditText(getContext()); LinearLayout.LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); _myText.setLayoutParams(params); _myText.setId(getEditTextId()); addView(_myText); _myText.setOnTouchListener(new OnSwipeTouchListener(getContext()) { @Override public void onSwipeDown() { } @Override public void onSwipeLeft() { CustomEditTextWithCheckbox.this.onSwipeLeft(); } @Override public void onSwipeUp() { } @Override public void onSwipeRight() { CustomEditTextWithCheckbox.this.onSwipeRight(); } }); }

but as I guess in OnSwipeTouchListener.OnTouch always returns true and so edittext does not get focus. I have also tryed to change onTouch

 public boolean onTouch(final View view, final MotionEvent motionEvent) { gestureDetector.onTouchEvent(motionEvent); return false; }

and it works, but still problem is that on swipe edittext gets focus when i want to swipe, And I understand why its working like that. But i need that if user does not swipe than on touch should return false, else true. Can anyone help

I found a good solution for my question here u need to change a bit SwipeDismissTouchListener this way

public class SwipeDismissTouchListener implements View.OnTouchListener { private int mSlop; private int mMinFlingVelocity; private int mMaxFlingVelocity; private long mAnimationTime; // Fixed properties private CustomEditTextWithCheckbox mView; private DismissCallbacks mCallbacks; private int mViewWidth = 1; // 1 and not 0 to prevent dividing by zero // Transient properties private float mDownX; private float mDownY; private boolean mSwiping; private int mSwipingSlop; private VelocityTracker mVelocityTracker; private float mTranslationX; public interface DismissCallbacks { boolean canDismiss(); void onDismiss(View view); } public SwipeDismissTouchListener(CustomEditTextWithCheckbox view, DismissCallbacks callbacks) { ViewConfiguration vc = ViewConfiguration.get(view.getContext()); mSlop = vc.getScaledTouchSlop(); mMinFlingVelocity = vc.getScaledMinimumFlingVelocity() * 16; mMaxFlingVelocity = vc.getScaledMaximumFlingVelocity(); mAnimationTime = view.getContext().getResources().getInteger( android.R.integer.config_shortAnimTime); mView = view; mCallbacks = callbacks; } @Override public boolean onTouch(View view, MotionEvent motionEvent) { // offset because the view is translated during swipe motionEvent.offsetLocation(mTranslationX, 0); if (mViewWidth < 2) { mViewWidth = mView.getWidth(); } switch (motionEvent.getActionMasked()) { case MotionEvent.ACTION_DOWN: { // TODO: ensure this is a finger, and set a flag mDownX = motionEvent.getRawX(); mDownY = motionEvent.getRawY(); if (mCallbacks.canDismiss()) { mVelocityTracker = VelocityTracker.obtain(); mVelocityTracker.addMovement(motionEvent); } return false; } case MotionEvent.ACTION_UP: { if (mVelocityTracker == null) { break; } float deltaX = motionEvent.getRawX() - mDownX; mVelocityTracker.addMovement(motionEvent); mVelocityTracker.computeCurrentVelocity(1000); float velocityX = mVelocityTracker.getXVelocity(); float absVelocityX = Math.abs(velocityX); float absVelocityY = Math.abs(mVelocityTracker.getYVelocity()); boolean dismissRight = false; if (Math.abs(deltaX) > mViewWidth / 2 && mSwiping) { dismissRight = deltaX > 0; } else if (mMinFlingVelocity <= absVelocityX && absVelocityX <= mMaxFlingVelocity && absVelocityY < absVelocityX && absVelocityY < absVelocityX && mSwiping) { dismissRight = mVelocityTracker.getXVelocity() > 0; } if (dismissRight) { mView.onSwipeRight(); } else if (mSwiping) { mView.onSwipeLeft(); } mVelocityTracker.recycle(); mVelocityTracker = null; mTranslationX = 0; mDownX = 0; mDownY = 0; mSwiping = false; break; } case MotionEvent.ACTION_CANCEL: { if (mVelocityTracker == null) { break; } mVelocityTracker.recycle(); mVelocityTracker = null; mTranslationX = 0; mDownX = 0; mDownY = 0; mSwiping = false; break; } case MotionEvent.ACTION_MOVE: { if (mVelocityTracker == null) { break; } mVelocityTracker.addMovement(motionEvent); float deltaX = motionEvent.getRawX() - mDownX; float deltaY = motionEvent.getRawY() - mDownY; if (Math.abs(deltaX) > mSlop && Math.abs(deltaY) < Math.abs(deltaX) / 2) { mSwiping = true; mSwipingSlop = (deltaX > 0 ? mSlop : -mSlop); mView.getParent().requestDisallowInterceptTouchEvent(true); MotionEvent cancelEvent = MotionEvent.obtain(motionEvent); cancelEvent.setAction(MotionEvent.ACTION_CANCEL | (motionEvent.getActionIndex() << MotionEvent.ACTION_POINTER_INDEX_SHIFT)); mView.onTouchEvent(cancelEvent); cancelEvent.recycle(); } break; } } return false; } }

doint this way it works perfectly, hope it will be helpfull
