The onTouchEvents() for nested view groups can be managed by the boolean onInterceptTouchEvent. The default value for the OnInterceptTouchEvent is false. The parent’s onTouchEvent is received before the child’s. If the OnInterceptTouchEvent returns false, it sends the motion event down the chain to the child’s OnTouchEvent handler. If it returns true the parent’s will handle … Read more
Done it finally by myself. Draw everything by applying this formula to (px,py) coordinates: float px = ev.getX() / mScaleFactor + rect.left; float py = ev.getY() / mScaleFactor + rect.top; rect = canvas.getClipBounds(); //Get them in on Draw function and apply above formula before drawing
Try using new Google Map API v2. It’s easy to use and you can add a marker on tap like this: map.setOnMapClickListener(new GoogleMap.OnMapClickListener() { @Override public void onMapClick(LatLng point) { allPoints.add(point); map.clear(); map.addMarker(new MarkerOptions().position(point)); } }); or in Kotlin: map.setOnMapClickListener { allPoints.add(it) map.clear() map.addMarker(MarkerOptions().position(it)) } Note that you might want to remember all your added … Read more
Check it out: UILabel *label = … label.userInteractionEnabled = YES; UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelTap)]; [label addGestureRecognizer:tapGesture]; The trick is to enable user interaction.
I think your best bet is to use a combination of the onLongClickListener() and onTouchListener() for that button. You’ll need to catch certain events on the touch listener since it will trigger for every touch event. Try something like the following: class Blah extends Activity { private Button mSpeak; private boolean isSpeakButtonLongPressed = false; @Override … Read more
Here’s another solution that is very simple and doesn’t require you to worry about the finger being moved. If you are basing a click as simply the distance moved then how can you differentiate a click and a long click. You could put more smarts into this and include the distance moved, but i’m yet … Read more
It turns out that [buttonObj sendActionsForControlEvents:UIControlEventTouchUpInside]; got me exactly what I needed, in this case. EDIT: Don’t forget to do this in the main thread, to get results similar to a user-press. For Swift 3: buttonObj.sendActions(for: .touchUpInside)
var touchmoved; $(‘button’).on(‘touchend’, function(e){ if(touchmoved != true){ // button click action } }).on(‘touchmove’, function(e){ touchmoved = true; }).on(‘touchstart’, function(){ touchmoved = false; });
This example shows how to add a gesture detector to a view. The layout is just a single View inside of an Activity. You can use the same method to add a gesture detector to any type of view. We will add the gesture detector to the green View. MainActivity.java The basic idea is to … Read more
Found this documentation that pretty much states that it’s not possible to do both: Android : Multi touch and TYPE_SYSTEM_OVERLAY They discuss workarounds but I don’t think any of them will actually work for exactly what I’m trying to do. Both given the events to the underlying app, and being able to snoop them to … Read more
