I am able to create and drag and drop activity successfully but the only problem I faced is if I drag the view more than about 30 times, the drag event will stop to initiate and I am unable to drag anything. What is the causes?I am using onTouch() to drag the view.

View 4 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.
I am trying to use "setClickable(false)" + "setLongClickable(false)" + "setFocusableInTouchMode(false)" to disable Touch Event for every views but failed. When mouse clicks, OnTouchEvent() of some view will still be called. What I want is only to disable Touch event because my application need not Touch and Touch event will disturb the running of app. Is there any way to disable Touch ?

View 2 Replies View RelatedI need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.
Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for example)?

View 3 Replies View RelatedI'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that.
At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in.
Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this.
Here is my problem : I have a view containing a listView. And each row of this listview is composed of a linearLayout, itself composed of three textview and a gridView. Here is a summary of my layout for one row:
......
I want to perform an action when the user click anywere on an item of the listview. So I try these two approaches on the listview : - myActivity.getListView().setOnTouchListener(new View.OnTouchListener () {...}) - myActivity.getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() { ...}) And here is the trouble : - when I click on the textview, it nearly works : the touch listener is called, but not the clicklistener - when I click on the gridView it doesn't work....the event is just dispatched to the element of the gridView.............
I have created a list activity where i have placed some items and i am using OnListItemClick to get the desired actions through D-pad and KeyLeft and KeyRight Buttons, In Emulator TouchEvent is not working , I want to know whether it works in real Handsets? How can i enable the TOuchEvent? also Can anyone please help me out in this.
View 2 Replies View RelatedI'd like to receive a TouchEvent in my Android application any time the screen is touched. Even if my application is not in focus.Is there an general even listener or intent filter I can write to achieve this? The goal is to write system wide gesture engine. So for example, if the user swiped up and then down, a certain application would be launched regardless of where the user is.
View 2 Replies View RelatedI'm working on a simple game: when you press a button on the screen, a character will run to certain direction. It's easy to support keyboard input. But, some phone doesn't go with a keyboard or even no a track ball. So I decided to draw a virtual "run" key on the screen (with opengl). When the user press the virtual key, I apply a velocity to the character. And when the user release the key, I disable the velocity to stop the character but there seems to be some touch event noisy. If my finger cannot press still, I will see millions of touch down and touch up events, instead of a single long pressing.
And occasionally, my program captured the touch down event when I touch the screen, but didn't capture touch up event. So my character will keep moving, even no finger is on the screen. I'm wondering if there is some way to reduce the touch event noisy and tell if the user is currently pressing on the screen, instead of only getting an event when touch up and down happen. It seems the system UI can detect long pressing, for example when you put a finger on one item of the list view widget, the entire item turns to orange. I just don't know how to detect pressing in my opengl game.
I like to know using which version of Android SDK we can develop multi touch handling. Does Android SDK 1.6 support multi touch? If yes, can i get some sample code, where i can have multiple imagebuttons placed on screen and clicking on all the imagebuttons at a time should detect multiple touch events?
View 2 Replies View RelatedAre following touch events supported by android platform or we have to implement them?
Touch event - Used to focus an item Tap - Execute action when finger is released Tap and hold - Long tap for some timeout Double tap - Tap twice without much delay Flick - Touch, hold, move and release quick Drag n drop - Touch, hold and drag Touch and move - Touch, hold, move and release in straight line
I can override onTouchEvent, but there is no x and y coordinates to set in the EditText or usual View.

View 1 Replies View RelatedAs a work around to the issue where a list item isn't focusable if it has a focusable child item (a comment by Romain Guy was that this was intended behavior, for accessibility reasons) I simply filled the listItem with two children, each of which is focusable - There's nowhere to directly touch on the listItem anymore, just it's children.
For the most part this is a useable workaround, effectively invisible to the user, except for one thing- Although you can scroll by swiping without issue, touching to *stop* the scroll no longer works- I imagine because the child item is capturing the touch event and not passing it to the parent listitem, at least while the scroll is in effect.
Is there a known workaround for this? Perhaps someway to "pass the baton" of the touch event back up to the parent listItem, or a way to change my design?
BTW- I know there's some built-in functonality for single/multiple choice listviews (checkbox listviews) - That doesn't actually help in my case. The app is a contact list, and the row children are a relativelayout (populated with contact info) and a clickable phone icon (a one-touch dial for the contact), which needs to be visible or invisible depending on whether the stored contact has a phone number.

Imagine I've drawn a cube. I want that user can push his finger over the cube and can rotate the cube and move it around the screen.
Is there any way to do that?
How can assign an event listener to touch and move events only when the user touch the cube?
UPDATE I want something like this: Rotate cube with fingers.
Just want to start out by saying this seems like a great site, hope you guys can help! I'm trying to use the structure laid out in LunarLander to create a simple game in which the user can drag some bitmaps around on the screen (the actual game is more complex, but that's not important).
