I understand calling onTouchEvent from views to get the location of the last touch as a motion event. How the heck can I tell that a figure is down on the screen and has not been lifted and when the finger is lifted?
For instance there is onKeyDown and onKeyUp for use when you are dealing with keyboard input. So how can I find out when on fingureUp happens?

I have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?
is there any application to get screen off by fast finger touch?

View 3 Replies View RelatedI found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?

View 1 Replies View RelatedI've noticed that I'm getting little tingling shocks to my right index finger whenever I touch the Evo's screen.What's even stranger is that I don't feel the sensation on any other fingers on either hand. Has anyone else had a similar experience with their evo screen and finger feeling little shocks?I'm not imagining this, and I'm wondering why the heck it's just my index finger?!? Maybe it's just more sensitive, but who knows.I would assume that the capacitive touchscreen technology is the culprit. I can live with the slight tingling, I just don't know why it's only on 1 finger!
View 8 Replies View RelatedAnyone else notice when you're on a phone call if you move your finger near the little dot to the left of the verizon logo the screen will turn off? It's annoying when multitasking because that functionality remains regardless of whether the phone call is the active screen or not. If you are watching the Google Navigation screen and you're on a call, move your finger near the little dot next to the verizon logo and the screen turns off.
View 3 Replies View RelatedI have got one big problem with the touch input of my Hero. The screen is too sensitive. I can navigate on the screen while my finger is about 5 cm away from it. I can choose what I want, but the screen takes the right horizontal position of my finger, but not the vertical. Anything I want to take, the screen takes the one on the bottom of the screen. The same when I want to write a message or something like this. I choose the "W" or "E", but the screen takes the "X" or "C". If the display goes on Standby and I wake it again, everything is good for a few seconds, but than the same mistake comes again. I already tried to wipe and install a new MCR, but nothing helps. I think, but I am not sure, that I have that problem after I have installed the htc keyboard on android 2.1, as I tried it for a few hours.

View 12 Replies View RelatedI can't find a tutorial on Google for my problem. I'm french and i don't find the best "google keywords" for to describe my goal. I decided to ask the question here.
I want to do an animation between views like on the Home or on the Calendar in week mode. I want the switch between the views follows the finger. As I have not released the pressure, I see a part of the current view an a part of the next view.
Currently, I use a AnimatorView and 2 gestures. But the change happens when the pressure is released, and it's not good.
Can someone explain to me how to do or where to find a tutorial that explain? ps : please, don't laugh about my english, it's worst when I speak with my very french accent :P

View 3 Replies View RelatedI was checking the possibility to allow painting on the screen of a surface (i.e. API demo Fingerpainting example), however when I checked it, this technic apparently only allows painting with the tip of your finger, if you try to use any other object (pencil, thick pen, etc.) it does not draw anything on the surface. Am I missing something here? Is there a way to allow other objects to draw things on a surface? Is this achievable and how should I proceed?

View 2 Replies View RelatedI have a ListView. When I click a row Item (which are just TextView instances) I want them to remain hilighted (default orange color). The default behavior is that they flash orange.
Strangely, if I use the key pad (arrow up/down) to move between items, it has the exact behavior I want. Why is the logic different between using the keypad or with finger tapping?
How can I make the ListView immediately stop scrolling on a finger down event? It keeps scrolling if I give it a big swipe and doesn't stop immediately if my finger is pressed down again. Any idea?

just downloaded, havent played yet, but if its like the Iphone one, very simple amusing game.
I'm having a conceptual problem with a simple application.
I have an empty FrameLayout and I want for a certain event to being continuously repeated until the finger leaves the display.
If I apply:
### code ###
frameLayout.setOnTouchListener(new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { myEvent(); return false; }});
With Android 4.1.1 I had a browser with 1-finger-zoom...will say, I could swipe left or right on the side of the screen to zoom in and out.
Now with 4.1.2 this feature isn't there any longer...
Any way to get this version of browser back? An app to flash or something like that?

View 3 Replies View RelatedI've got a view where I override onTouchEvent to detect touching the view with a finger and also to detect lifting the finger from the view. I'm getting the ACTION_DOWN event but not the ACTION_UP event. In fact, onTouchEvent isn't getting called when I life my finger. Could it be that the finger-down and then finger-up is considered a click event and so onTouchEvent is not called? If so, what use is ACTION_UP?
View 15 Replies View RelatedIn the Android API examples there is a Snake game. This game uses a class called SnakeView, which inherits from TileView.
I am doing something very similar to this. I am inheriting from TileView to create a class (SkyView), which will become a square board for a board game (similar to the board for Checkers).
However, I would like for my game board to be 400x400 pixels in size, which will be bigger than the screens of some Android devices (such as the G1). And I would like for the user to be able to freely scroll and drag the board around with their finger (both horizontal and vertical scrolling/dragging).
Can someone please point me in the correct direction for implementing this? The board must be no smaller than 400x400px in size. And however much of the board that can be displayed at once on the screen, should be displayed at once.
Should I wrap my SkyView widget in an AbsoluteLayout and use Scrollbars? If so, what Scrollbar properties to I need to use? I played around with Scrollbars in both directions but couldn't get it to work. Is there another view layout I should put it inside? Code examples would be nice! Thanks for the help. I am at a loss with this one.
